I already installed VS CODE on my Mac and did all the settings. I put codes in it, and it responded, "/bin/sh: python: command not found."
I tried all kinds of methods, but they didn't seem to help.
Here is a screenshot of the error.
Please help me.
Probably the path of the python interpreter is misconfigured.
You can open a terminal and write the following command: $ whereis python
If this command does not return anything, it is likely that python is not installed (or undefined in the var env 'path') on your Mac.
If you have a path to an interpreter, change the interpreter path used by vscode.
Go to the settings and edit the field : "python : interpreter path" with the right one.
Good day.
i have installed VSC and set up the necessary dependencies for python.
Using a simple hello world example, i can run the file using run and debug option.
I can also run it by manually typing python hello.py in the terminal.
However, when i use the run button (top right hand corner), i get an error.
Can i check how to solve this?
Thank you.
I usually use pycharm for coding.
My question is how I can replace execution by IDE to command prompt execution. IDE makes it easy to set all python environments.
Windows 10 / Anaconda 3 / Python 3.7
My goal is to execute python program by windows scheduler.
Please let me know how to execute it.
Thanks.
Just open a command prompt, and then type:
python path_to_your_code/your_code.py
If this gives you errors that numpy, pandas etc are not installed then it means that the interpreter being used by your IDE (where you did not get such errors) is not the same one pointed at by python in command line.
If you're using a virtual environment or a python installation other than the default one you can just replace the python with a full path to the python binary in the environment you are using. So assuming your IDE is using the Anaconda environment, try this from command line:
c:\Anaconda3\python.exe path_to_your_code\your_code.py
Adding c:\Anaconda3 to PATH will not help if you already have another version of Python installed elsewhere, it will just mean that you now have two python.exe files in your path and python will still point at the same one.
However if where python already returns the path above, it means that your IDE is not using this interpreter and you'll need to find which one it is using. You can check this by looking in the Project Interpreter options or by running this script
import sys
print(sys.executable)
My GUI script that is a PyQt5 file (.pyw extension) does work when running on my IDE with a build configuration that tells the compiler to run the script with python3:
And it also works when i tell to the regular terminal on Linux to run same script with python3 like this:
When runned with the default python (python2.7) on a regular terminal it tells: ImportError: No module named PyQt5.QtWidgets.
My code does it have these lines on the start to tell that is a python3 script like: #!/usr/bin/python3 or #!/usr/bin/env python3 (I have python3 installed).
When double clicked on the Linux Mint File Explorer the cursor turns crosshair and nothing happends, with the terminal option, same happends and a empty terminal shows. Im talking these options
I guess Linux Mint still runs the scripts with python2.7 even when I added the bash lines to tell
Someone knows why the lines:
#!/usr/bin/python3
#!/usr/bin/env python3
doesnt work when just double click?
I want to run the script from the Linux File Explorer without the need of an IDE or using the terminal.
Try chmod +x file.py and run it in terminal by using ./file.py also try lunching the file from a different path, like python3 ~/path/to/file.py and see if the error persists
I am using Python 3.5.2 version on Windows 7 and tried using python3 app.py. I am getting this error message:
'python3' is not recognized as an internal or external command,
operable program or batch file.
Is there any specific cause about why the python3 command is not working?
I also verified that the PATH is added to environment variables.
There is no python3.exe file, that is why it fails.
Try:
py
instead.
py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by
py -2 or
py -3
You can also try this:
Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37
In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.
Python3.exe is not defined in windows
Specify the path for required version of python when you need to used it by creating virtual environment for your project
Python 3
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
Python2
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
then activate the environment using
.\environment\Scripts\activate.ps1
Yes, I think for Windows users you need to change all the python3 calls to python to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:
cd C:\Python3
mklink python3.exe python.exe
Use a (soft) symbolic link in Linux:
cd /usr/bin/python3
ln -s python.exe python3.exe
In my case I have a git hook on commit, specified by admin. So it was not very convenient for me to change the script (with python3 calls).
And the simplest workaround was just to copy python.exe to python3.exe.
Now I could launch both python and python3.
If python2 is not installed on your computer, you can try with just python instead of python3
For Python 27
virtualenv -p C:\Python27\python.exe django_concurrent_env
For Pyton36
virtualenv -p C:\Python36\python.exe django_concurrent_env
Enter the command to start up the server in that directory:
py -3.7 -m http.server
I had a related issue after installing windows 11, where python3 in cmd would open the windows store. I was able to sort it out between this post and this other one. In short, I reinstalled python and made sure to add it to PATH. Then, in settings, Apps > Apps & Features > App Execution aliases. Here, all I had to do was make sure that every single python .exe (including idle and pip) were turned off EXCEPT FOR the python3.exe alias. Now it works like a charm.
FWIW:
The root of this issue is not with you or with python. Apparently, Microsoft wanted to make installing python easier for young kiddos getting interested in coding, so they automatically add an executable to PATH. For those of us that already have this executable, it can cause these issues.
Found out instead press the play button the top right and it should work in visual studios:
Do not disable according to first answer
Saying python3 in the command will not work by default.
After figuring out the problem with the modules (Solution): https://youtu.be/paRXeLurjE4
Summary:
To import python modules in case of problem to import modules:
Hover over python in search:
Click open in folder
Hover over and right click
click properties
copy everything in path before \python.exe
close those windows
For cmd (administrator):
cd --path that was copied--
then python -m pip install --upgrade pip
cd Scripts
pip install "Name of Package" such as pip install --module (package) --
Im on win10 and have 3.7, 3.8 and 3.10 installed.
For me "python" launches version 3.10 and does not accept commands (like -3.7), "py" launches newest version but does accept commands, and "python3" does nothing.
Uninstalled 3.10 and "python" now does nothing, and "py" launches 3.8.
I am unable to add a comment, but the mlink option presented in this answer above https://stackoverflow.com/a/55229666/8441472 by #Stanislav preserves cross-platform shebangs at the top of scripts (#!/usr/bin/env python3) and launches the right python.
(Even if you install python from python.org, Windows will direct you to the app marketplace nowadays if you type python3 on the command line. If you type python on the same cli it will launch the python.org version repl. It leads to scripts that generate no output, but more likely silently failed completely. I don't know ho common this is but have experienced it on a couple of different devices)
If you have this at the top of your script to ensure you launch python3 and don't feel like editing everything you own, it is not a bad approach at all... lol.
