My Flask App server is running but I have three imports that cannot be resolved.
I have tried:
reinstalling the imports individually
reinstalling requirements.txt
I configured VSCode Workspace with an extra path to my project folder (there is now a .vscode file within the root of my project folder where it was not before)
I have updated my venv path settings in VSCode
Here is my file structure:
- > .vscode
- > client *(React front end)*
- > data
- > server *(Python/Flask back end)*
- > app
- > venv
- config.py
- README.md
- requirements.txt *(this contains the 3 unresolved, along with several that are resolving)*
- .env
- .flaskenv
- .gitignore
- requirements.txt
Unfortunately none of these things have resolved my imports issue and my routes are still not working. Any ideas/suggestions?
Open the Command Palette (Ctrl+Shift+P), then select the Python: Select Interpreter. From the list, select the virtual environment in your project folder that starts with .env.
Run Terminal: Create New Integrated Terminal (Ctrl+Shift+` or from the Command Palette), which creates a terminal and automatically activates the virtual environment by running its activation script.
Install sqlalchemy and mongoengine with command pip install. Once installing them successfully, there will intellisense when you import them and no warnings shown.
Besides, the folder .vscode is to store Workspace settings as well as debugging and task configurations.
If you are using a virtual environment, and even after trying pip installing all the necessary libraries, you have to select the python interpreter that exists in the virtual environment folder.
(Ctrl+Shift+P) then search for "Python: Select Interpreter"
Click "Enter interpreter path" followed by "Find.."
Navigate to your project virtual environment folder
Go into "Scripts" folder and then select "python.exe" as the interpreter.
These steps allow you to select the right python interpreter associated with the project's virtual environment.
Open the Command Palette (Ctrl+Shift+P), then select Python: Clear Cache and Reload window.
Voila, all the import errors vanished.
I specified a path to the python interpreter I'm using within the settings.json file contained in the project repo's .vscode folder.
"python.pythonPath": "path-to-interpreter.python.exe"

I ran into this error after an upgrade of my local python version (brew -> manual install), even though the specified interpreter was already /usr/local/bin/python3.
CMD + Shift + P and re-selecting the [same] interpreter fixed the error.
In hindsight, I suspect that a restart of VSCode could have also fixed this. 🤷‍♂️
Perhaps VSCode is using the incorrect Python path for this reason. A base interpreter should be used instead of the vscode interpreter, if necessary.
After verifying my Python interpreter was sourced correctly in VS Code, I simply cleaned my env and reinstalled the project locally and the import errors disappeared. I personally had an odd VS Code/Pylance cache and reinstalling the dependencies and modules fixed it for me.
I was getting the very same error you have and none of the solutions presented here worked me.
I work on a windows machine. I use miniconda to manage my virtual environments. And when I'm coding I launch every program from the command prompt (cmd), including Vscode.
Even tough inside Vscode the python evironment was correctly settled I was getting the very same import error that you mention. The interesting part of it was that I wasn't having any problems to run the code, it was working as usuall. But when coding I wasn't able to see the functions related to the libraries with the import error.
The solution:
Activate the correct conda env for the project before launch Vscode from the command prompt.
Why does this happen?
I BELIVE that this happen because when you don't activate any conda env before launch Vscode. The base conda env is loaded as default. That generates the import conflict. (You can chek this out installing those packagues into the environment and running everything just as you have been doing)

My operation system is macOs Ventura
This problem happens as i think only with VSC, becuase opening same folder via PyCharm all is importing successfully.
[Screenshot of Error, pipenv --venv, pipenv --wheree and pipenv --graph]:(https://i.stack.imgur.com/PR3Vh.png
I have created directory (folder), created local virtual environment via pipenv install django and active its via pipenv shell. Imports working good ... but just in PyCharm.
I have tried to reinstall VSC — not helped.
I have assumed that in sys.path wasn’t written this path /Users/sheenaz/.local/share/virtualenvs/Polls-njzI0GZr/lib/python3.11/site-packages — it was.
I have tried to reinstall pipenv and django — not helped.
As you can see that interpretator has entered correctly, but still doesn’t work (modules not importing).
I want that my modules will able to importing, can sombedy help?
I know answer!
At first it's a problem not with VSC or pipenv, It's just a problem with Code Runner extension that I use.
So, by deafault Code Runner python executor map is python or python3, you need substitute this by your virual environment executor or inerpreter.
To fix this go to the settings.json or to VSC code and in settings search type Code-runner: Executor Map. Now you in settings.json either or again).
Search for key "code-runner.executorMap" in dict and as you have finded then search key "python" and by default you will get defeault value like "python" or "python3" maybe. You need to change this value to your python virtual environment executor map (interpreter).
In my instance it is the pipenv interpreter — /Users/sheenaz/.local/share/virtualenvs/PLPY-ELrCBZFZ/bin/python3
Install specific debugger in VSCode. In my situation, debugger for OpevCV:
Because in Pycharm you install package with everything needed, while in VSC you need to additionally install the debugger.
Same problem on MacOS Ventura, had no problem running the same environment on MacOS Monterey, where imports work. Here assumed it's a path issue, after solving dependencies
export PYTHONPATH=/path/to/dir:$PYTHONPATH
then activate imports, by specifying both interpreter and path in VSCode (I have anaconda on Ventura and Python through Brew on the Monterey setup). Both now work.
In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio
Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module
My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.
Download anaconda
https://anaconda.org/
once done installing anaconda...
Go into Settings -> Project Settings -> Project Interpreter.
Then navigate to the "Paths" tab and search for /anaconda/bin/python
click apply
This error suddenly came up when I created a new Django project. I used pip to install all the packages in the virtual environment.
I had exactly the same problem and there are several solutions out there, but only #Neha's answer has brought me to the point. The problem here is really simple. VS Code uses your "main" Python interpreter, whereas you should use the one in your virtual environment for Django.
In other words, I have my main Python installation here:
c:\users\yourName\appdata\local\programs\python\python39.
And my VS Code has pointed to exactly this interpreter. But my Django was installed in this path:
c:\users\yourName\source\vscode-repos\basic-app\backend-service\venvs\lib\site-packages.
In order to solve it click on the
VS Code bar with Python Interpreter, you will then see a pop-up window. Choose + Enter interpreter path... then Find.... It will open File Explorer for you. Go to your virtual environment folder, where you have your Django installed (in my case it the vscode-repos\basic-app\backend-service\venvs folder), inside of it go to the Scripts folder and pick python.exe, like this. And you are good to go!
Actually all of the answers were right , but what worked for me is:
Type pip show Django in vsc terminal
Go to the path of intallation mentioned there
It will be inside "lib" by default..go back to scripts
Inside the scripts , there will be python .exe app
Choose this as your interpreter (as per above answers)
Select the Python interpreter in which you have created the virtual environment. I had the same error and this solution worked.
Below is a screenshot that you can refer to.
If you are using VScode, click the python version on the bottom left corner and select the venv where you have installed the packages.
For anyone who can't see the virtual environment then click on the python version below right corner of vscode,click on Enter Interpretor Path,click find,chose the folder that you are working,click on virtual environment name ,then click bin and select python version and the warning will be gone.
In my case (on MacOS) the problem was caused by creating venv using default arguments.
I don't have Scripts directory, but I've got bin inside. The python3 -m venv my_venv command was creating symlinks to python and python3 executables which was confusing for the VSCode. After removing and creating again the venv with below command everything started to work
python3 -m venv --upgrade-deps --copies my_venv
Go to the Python(Extentions) below your screen Like this then select interpreter tab will pop up, then select C:\Python39\python.exe Like this.Hope it helps
What worked for me was to install django within my virtualenv. All other settings were correct in Visual Studio Code.
So I thought I installed anaconda and Django correctly but I guess I didn't because my django-admin commands don't work. As you can see here, I have the file paths for a couple Django files all screwed up:
/Users/user/anaconda3/bin/django-admin
/Users/user/anaconda3/bin/django-admin.py
/Users/user/anaconda3/lib/python3.8/site-packages/Django-3.1.5.dist-info/*
/Users/user/anaconda3/lib/python3.8/site-packages/django/*
This makes it so I can't run any django-admin commands that I need to run to start a new project in PyCharm.
You can try change the project structure in Pycharm settings
I found the issue--make sure that you install djangorestframework inside the virtual environment you are working in, not the base one.
I want to debug an application using Python and Flask in VSCode. I have installed Flask and the app runs perfectly fine through cmd. But, when I try to debug it through VSCode, it gives the following error:
cd 'c:\Users\Aditi\CleanHandymanApp';
${env:FLASK_APP}='NewApp'; ${env:PYTHONIOENCODING}='UTF-8';
${env:PYTHONUNBUFFERED}='1'; & 'C:\Users\Aditi\envs\CleanHandymanApp\Scripts\python.exe'
'c:\Users\Aditi\.vscode\extensions\ms-python.python-2018.10.1\pythonFiles\experimental\ptvsd_launcher.py' '--client' '--host'
'localhost' '--port' '63143' '-m' 'flask' 'run' '--no-debugger' '--no-reload'
No module named flask
Can you please help me.
This error message can occur if you installed the python3 version of flask but Visual Studio Code tries to run your project with python2.
Make sure to select the correct version of python in the editor. This can be done by running the command Python: Select Interpreter from the Command Palette (Ctrl+Shift+P).
Activate your virtualenv and run
pip3 install -r requirements.txt
to reinstall all packages inside the venv.
For some reason VS Code thought I was missing all my packages the first time I debugged even though the app was running fine locally.
Sometimes you can get this error if you loaded Flask into a folder which has sub-files. For instance, if you loaded flask into the parent folder with the virtual shell instance but you're running your code in the child file (let's say parent is called crypto_files and inside that is a python source code file called blockchain.py ), then in order to get flask to run properly you'd have to run the file like this:
python crypto_files/blockchain.py
This allows your machine to see Flask running inside crypto_files but also run blockchain.py .
OR, it's possibly you could just reload Flask into the sub(child)file... blockchain.py and then you'd run it from within the subfile.
This complication is mainly due to modern "virtual instances" and shells which are basically like creating a virtual computer-machine inside your ACTUAL hard machine. Flask does this to avoid running everywhere, and since Flask is modular it allows each of your projects to run different modular configurations of Flask to suit each project precisely. The alternative would be awful: you'd have to load the fattest version of Flask with dozens of add-ons for each project, and so all your git and all your projects would have tons of extra code. Flask is built to be very small at the core to avoid this problem (too verbose!).
If you have installed flask in virtual environment, you should have activated it first.
source /path to env dir/bin/activate #in linux
workon 'name of env' #windows
Another option is add sys.path.append('d:/programas/anaconda3/lib/site-packages') in c:\Users\Aditi.vscode\extensions\ms-python.python-2018.10.1\pythonFiles\experimental\ptvsd_launcher.py
Being that "d:/programas/anaconda3/lib/site-packages" should be modified by your local python packages.
Use this command in the terminal instead of selecting run code:
python3 "insert your file name here without the quotes"
e.g.: python3 example.py
I had a variant of the issue mentioned by #confusius. I had installed both Python 3.9 and Python 3.10. I had added Flask to Python 3.10. I had been using one vscode workspace which had selected Python 3.10. I started another project in a different vscode workspace and it had selected Python 3.9 by default, which I didn't notice because I thought it would select the same Python I had already selected in the other workspace.
