I am trying to use Sublime text IDE for my Python projects. But after ensuring the build system, I am not able to run any program there. I am getting ModuleNotFoundError as soon as I import modules like NumPy, pandas.
Here is some useful information:
> import sys
> print (sys.executable)
/usr/local/bin/python3
The information on pip and Python are following
> which pip
/Users/harish/opt/anaconda3/bin/pip
> which python
/Users/harish/opt/anaconda3/bin/python
I have been using pip to install all the python modules.
I have searched extensively internet, I find no solution.
I am using MacBook Pro, macOS Catalonia. (my MPB is an old fart and Apple does not find it worthy to run BigSur)
As you can see from the outputs of sys.executable (run within Sublime) and which python (run in the shell), you are not using the same Python binary in both places. To set up Sublime to use the correct one where you installed your packages with pip, you'll need to create a new build system.
In Sublime, select Tools → Build System → New Build System… and change its contents to the following:
{
"cmd": [
"/Users/harish/opt/anaconda3/bin/python", "-u", "$file"
],
"working_dir": "$file_path",
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
Hit Save, which will automagically open up your Packages/User folder, and save it there as Python_Anaconda.sublime-build or something like that. Just don't name it Python.sublime-build, as a build system with that name already exists.
Now, select Tools → Build System → Python_Anaconda (or whatever you named it), and you should be able to run programs with the modules you installed previously.

I'm trying to convert a fairly simple Python program to an executable and couldn't find what I was looking for, so I have a few questions (I'm running Python 3.6):
The methods of doing this that I have found so far are as follows
downloading an old version of Python and using pyinstaller/py2exe
setting up a virtual environment in Python 3.6 that will allow me to do 1.
downloading a Python to C++ converter and using that.
Here is what I've tried/what problems I've run into.
I installed pyinstaller before the required download before it (pypi-something) so it did not work. After downloading the prerequisite file, pyinstaller still does not recognize it.
If I'm setting up a virtualenv in Python 2.7, do I actually need to have Python 2.7 installed?
similarly, the only python to C++ converters I see work only up until Python 3.5 - do I need to download and use this version if attempting this?
Steps to convert .py to .exe in Python 3.6
Install Python 3.6.
Install cx_Freeze, (open your command prompt and type pip install cx_Freeze.
Install idna, (open your command prompt and type pip install idna.
Write a .py program named myfirstprog.py.
Create a new python file named setup.py on the current directory of your script.
In the setup.py file, copy the code below and save it.
With shift pressed right click on the same directory, so you are able to open a command prompt window.
In the prompt, type python setup.py build
If your script is error free, then there will be no problem on creating application.
Check the newly created folder build. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.
See the original script in my blog.
setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable("myfirstprog.py", base=base)]
packages = ["idna"]
options = {
'build_exe': {
'packages':packages,
},
}
setup(
name = "<any name>",
options = options,
version = "<any number>",
description = '<any description>',
executables = executables
)
EDIT:
be sure that instead of myfirstprog.py you should put your .pyextension file name as created in step 4;
you should include each imported package in your .py into packages list (ex: packages = ["idna", "os","sys"])
any name, any number, any description in setup.py file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = '' )
the imported packages must be installed before you start step 8.
Python 3.6 is supported by PyInstaller.
Open a cmd window in your Python folder (open a command window and use cd or while holding shift, right click it on Windows Explorer and choose 'Open command window here'). Then just enter
pip install pyinstaller
And that's it.
The simplest way to use it is by entering on your command prompt
pyinstaller file_name.py
For more details on how to use it, take a look at this question.
There is an open source project called auto-py-to-exe on GitHub. Actually it also just uses PyInstaller internally but since it is has a simple GUI that controls PyInstaller it may be a comfortable alternative. It can also output a standalone file in contrast to other solutions. They also provide a video showing how to set it up.
GUI:
Output:
Alternatively use pyinstaller directly:
pip install pyinstaller
pyinstaller filename
I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.
Here's the pypi
https://pypi.python.org/pypi/cx_Freeze
The documentation shows that there is more than one way to do it, depending on your needs.
http://cx-freeze.readthedocs.io/en/latest/overview.html
I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.
How do I use cx_freeze?
Now you can convert it by using PyInstaller. It works with even Python 3.
Steps:
Fire up your PC
Open command prompt
Enter command pip install pyinstaller
When it is installed, use the command 'cd' to go to the working directory.
Run command pyinstaller <filename>
I've been using Nuitka and PyInstaller with my package, PySimpleGUI.
Nuitka
There were issues getting tkinter to compile with Nuikta. One of the project contributors developed a script that fixed the problem.
If you're not using tkinter it may "just work" for you. If you are using tkinter say so and I'll try to get the script and instructions published.
PyInstaller
I'm running 3.6 and PyInstaller is working great!
The command I use to create my exe file is:
pyinstaller -wF myfile.py
The -wF will create a single EXE file. Because all of my programs have a GUI and I do not want to command window to show, the -w option will hide the command window.
This is as close to getting what looks like a Winforms program to run that was written in Python.
[Update 20-Jul-2019]
There is PySimpleGUI GUI based solution that uses PyInstaller. It uses PySimpleGUI. It's called pysimplegui-exemaker and can be pip installed.
pip install PySimpleGUI-exemaker
To run it after installing:
python -m pysimplegui-exemaker.pysimplegui-exemaker
The best and easiest way is auto-py-to-exe for sure, and I have given all the steps and red flags below which will take you just 5 mins to get a final .exe file as you don't have to learn anything to use it.
1.) It may not work for python 3.9 on some devices I guess.
2.) While installing python, if you had selected 'add python 3.x to path', open command prompt from start menu and you will have to type pip install auto-py-to-exe to install it. You will have to press enter on command prompt to get the result of the line that you are typing.
3.) Once it is installed, on command prompt itself, you can simply type just auto-py-to-exe to open it. It will open a new window. It may take up to a minute the first time. Also, closing command prompt will close auto-py-to-exe also so don't close it till you have your .exe file ready.
4.) There will be buttons for everything you need to make a .exe file and the screenshot of it is shared below. Also, for the icon, you need a .ico file instead of an image so to convert it, you can use https://convertio.co/
5.) If your script uses external files, you can add them through auto-py-to-exe and in the script, you will have to do some changes to their path. First, you have to write import sys if not written already, second, you have to make a variable for eg, location=getattr(sys,"_MEIPASS",".")+"/", third, the location of example.png would be location+"/example.png" if it is not in any folder.
6.) If it is showing any error, it may probably be because of a module called setuptools not being at the latest version. To upgrade it to the latest version, on command prompt, you will have to write pip install --upgrade setuptools. Also, in the script, writing import setuptools may help. If the version of setuptools is more than 50.0.0 then everything should be fine.
7.) After all these steps, in auto-py-to-exe, when the conversion is complete, the .exe file will be in the folder that you would have chosen (by default, it is 'c:/users/name/output') or it would have been removed by your antivirus if you have one. Every antivirus has different methods to restore a file so just experiment if you don't know.
Here is how the simple GUI of auto-py-to-exe can be used to make a .exe file.
PyOxidizer can be an option here. It's pretty popular with 3.3k stars on Github. Its documentation says
PyOxidizer is capable of producing a single file executable - with a copy of Python and all its dependencies statically linked and all resources (like .pyc files) embedded in the executable. You can copy a single executable file to another machine and run a Python application contained within. It just works.
While I'm not sure if it is capable of producing .exe file PyOxidizer definitely helps with packaging and distribution.
Just installed Anaconda distribution and now any time I try to run python by double clicking a script, or executing it in the command prompt (I'm using windows 10) , it looks for libraries in the anaconda folder rather than my python folder, and then crashes. If I run via the command prompt, I'm able to see the error, which is:
File "C:\Users\bob\Anaconda3\lib\site-packages\pandas__init__.py",
line 19, in
"Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']
I've uninstalled and re-installed Python and numpy multiple times, but it's getting installed in the default python folder, and since I installed the anaconda distribution, the python launcher always looks in the Anaconda folder. I have to run modules from IDLE or not at all.
Is there any way to get Anaconda to play nice with the standard python installation? I'd really like to be able to quickly and easily double click python scripts to run them.
Anaconda comes with pip , you should not need a separate installation. If you need a library not available in anaconda then you would use pip. Both will store your downloaded packages in site-packages. In your scripts folder you should have [usually only one] reference to python. Generally I think anaconda is the preferred repository. I would consider removing " standard installation". If you need two for some reason make sure only one is in your environment variable path. Assuming you don't have the anaconda version in your path; go to the scripts folder ,in the cmd prompt and type
python myscript.py
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.
Really excited about using Typescript on the Mac however, even after a full day of troubleshooting, unable to get it to compile in SublimeText. Followed these directions (the first at the top) to install nodes and npm>
https://gist.github.com/isaacs/579814
Installed Typescript
sudo npm install -g typescript
Installed the syntax highlighting package for sublime
http://msopentech.com/blog/2012/10/01/sublime-text-vi-emacs-typescript-enabled/
Created a build file 'typescript.sublime-build as follows
{
"selector": "source.ts",
"cmd": ["tsc", "$file"],
"path": "/usr/local/bin",
"file_regex": "^(.+?) \\((\\d+),(\\d+)\\): (.+)$"
}
When I type $which node I get
/usr/local/bin/node
When I type $which tsc I get
/Users/<username>/local/bin/tsc
BUT, whenever I try to compile even the simplest .ts file in SublimeText the first effort message I get is
[Errno 2] No such file or directory
Can anyone suggest further troubleshooting steps?
I struggled with a little too. It seems the PATH is quite different when trying to run commands directly from the build system than the terminal, and this is a cause of problems.
What I did as a simple workaround was just set my command to run a Bash script, i.e. in the sublime.project file have the command as..
"cmd": ["./build.sh"]
.. and then in the build.sh script in my project folder simply run the compiler, i.e..
#! /bin/bash
tsc --target ES5 foo.ts
Obviously this assumes foo.ts pulls in all the other project files so they get compiled (or you could glob for the files on the command-line seeing as you're running a Bash command).
This might be a quick and simple solution for you.
You could do what my team mates do. Use Sublime Text for text editing with a grunt watch in the background compiling any files that change : https://github.com/basarat/grunt-ts
On OS X 10.7.2, I created a small build system in Sublime Text 2 that will compile my LESS files into CSS for me, but it seems to be having a problem.
{
"cmd": ["/usr/local/lib/node_modules/less/bin/lessc", "-x", "$file", "$file_path/$file_base_name.css"],
"selector": ["source.less"]
}
I've installed Node.js v0.6.6 using the standard OS X installer package, and installed less v1.1.6 using npm into the /usr/local/lib/node_modules folder. Switching to my build system works fine, but when I attempt to run the build I get the following error message:
[Finished]env: node: No such file or directory
Running the command from the terminal works perfectly fine, it's just Sublime that is taking issue.
Another way to solve this is to install LESS globally, as it looks like you've already done:
npm install -g less
Then pass shell=true as a variable in the build script:
{
"shell" : true,
"cmd": ["lessc", "-x", "$file", "$file_path/$file_base_name.css"],
"selector": "source.css.less"
}
That runs the lessc command in the terminal in a way you'd expect.
While I am still unsure as to why there is a difference between Sublime Text 2 and running the build system in the terminal, I fixed the issue I was encountering by explicitly adding the value of $PATH to my build system.
Acting on the documentation provided on the Sublime Text Help page, I set up my build system to be the following:
{
"cmd": ["/usr/local/lib/node_modules/less/bin/lessc", "-x", "$file", "$file_path/$file_base_name.css"],
"selector": "source.css.less",
"path": "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin: No such file or directory"
}
