I have just started working on my new pc and just to get a feel for it I wanted first to start working on python files, so I started first by just wanting to run WSL on windows and it installed correctly but when I want to run any python using the run python file on the top right on VS code, this is what gets executed $ C:/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe f:/Projects/hello.py
And this is the error: -bash: C:/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe: No such file or directory
I have no idea what's causing it but when I run the file using 'Shift + Enter' which is: Python: Run Selection/Line in Python Terminal it seems to run the single line correctly but it gives me this error instead:
print("Hello, world")
-bash: syntax error near unexpected token `"Hello, world"'
but when I run it using python3 hello.py, it works perfectly fine?! I'm so lost as to why this is happening and how could I fix it.
Might be relevant: I'm using windows 10, installed python 3.10.2 from windows store, all of that is in VS code and the python code is one line: print("Hello, world") and I changed the permissions of Local/Microsoft/WindowsApps so it's now accessible by all users to view/read/edit/run, made sure that python3.10.exe exists(on the WindowsApps and it works perfectly) and reinstalled it many times, tired python3.9, and tried to install python from the website instead of the windows store and still the same, manually added python to PATH and tried .venv and didn't work. when I launch python3.10.exe outside vs code it seems to run perfectly, I have worked with python before and it used to work fine now I don't know what's wrong.
I have seen other questions of the same problem I'm having here but none of them solve the problem.
No such file or directory C:/Users/...
For wsl, the Windows filesystem is accessible, but it has a different path. It is mounted under the /mnt folder. So you would find your python .exe under /mnt/c/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe. This said, the executable file is meant to work on Windows, and it doesn't really makes sense to use it on Linux when you could run python within your wsl distro.
python3 works perfectly fine
This is because most Linux distributions come with python3 pre-installed, so you can use it already. To see where it is located, you can run the command which python3, or python3 --version to check its version.
If you want to change version, you may consider download it from you package manager, apt.
I also suggest to install python3-pip if you don't have it already to get the pip package manager for python.
In my case when I ran into this.. I discovered pyenv. This allows you to download more than one version of python. You can then go into a specific directory, such as your python project and issue a python local 3.10.0 (for example). Here's a link on how to install it as well as poetry which is a virtual environment manager that is become very popular. You can also create an alias for python that works off of this. I add this command to my alias file and source it from my .bashrc. alias python='pyenv exec python3'

I've gotten this to work relatively easy on my Mac I with django but for some reason Windows has been a heartache.
the problem is that in the console I can only get py to start executing python.
python and python3 do not work whatsoever
and also I can't get pip to install either because the py command won't execute it but python and python3 just open the windows store.
I've installed python to the path with the installer and I made the location of the file C:\Python\Python39
changed the hierarchy in the PATH in user variables and system variables to where python is at the top in both.
I've edited the vscode settings
I've also turned off the App execution aliases. That did nothing.
I'm at a complete loss so if any one has any advice I'd be so appreciative.
This tutorial helped me make pip working when I started programing

I'm going through the Flask tutorial, and I encounter a problem where I can't use pip (and thus anything else really) a venv in Powershell. The same flask app runs correctly in an Ubuntu terminal with Python 3.6.6 in WSL.
The problem seems to depend on the directory, which makes me think it's somehow related to file path length; I enabled long file paths in the windows Group Editor but this hasn't fixed the problem. In the below steps my venv directory is c:\users\rwgpu\google-drive\code\flask-tutorial\winEnvflaskr\ and I experience the error, but everything works correctly in the directory C:\python\test\testVenv. (in each case I'm running the commands in the directory one up from the listed above, flask-tutorial and test respectively)
Minimal steps to reproduce are:
Completely fresh Python 3.7 installation.
Change directory to app folder.
py -m venv winEnvFlaskr
./winEnvFlaskr/Scripts/activate
pip list
The ultimate goal is to then
pip install FLask
and run the Flask tutorial app. Again, all steps work correctly in Bash on Ubuntu in WSL (running its own Python) and in a different windows directory with the same Python 3.7.
After pip list I get the error:
Fatal error in launcher: Unable to create process using '"c:\users\rwgpu\google-drive\code\flask-tutorial\winenvflaskr\scripts\python.exe" "C:\Users\rwgpu\Google-Drive\Code\flask-tutorial\winEnvFlaskr\Scripts\pip.exe" list'
and if I try
python -m pip list
I get nothing; the terminal hangs for a second and returns with no output. If I run
py -m pip install -U pip
in the bugged venv it will try to install and report success. It will do this again, and will never report "requirement already satisfied" which would be correct.
I had the same problem on Windows with running flask in command line from venv(for example, "(venv)...\flask run"). I resolved the problem with changing path in flask.exe code(open "your_venv\Scripts\flask.exe" with notepad or etc.): in my way I correct the 436-th line at the end; you need to put there "your_absolute_path_to_venv\Scripts\python.exe" instead of the path indicated there.
Good luck!
Well, I still don't know why this was happening -- it persisted through deleting and recreating the venv (obviously), but when I deleted the entire folder, that somehow cleared it up. I just copied the code into a new directory in the same parent and everything seems to be working ¯\_(ツ)_/¯
If anyone knows what would cause this in my case I still welcome input.
I seem to have problem launching python from command line. I tried various things with no success.
Problem: When trying to run python from the command line, there is no response i.e. I do not get message about 'command not found' and console does not launch. Only option to open python console is to run C:\Python34\python.exe directly. Running using python command does not work even when in the python directory but python.exe launches. Issue with the launching this way is that python console is launched in new window. This whole problem is present only on one machine while on my other machine I am able to run python correctly and console launches in the command prompt window from which the python command was executed.
PATH is correctly set to
C:\Python34\;C:\Python34\Scripts;...
and where python correctly returns C:\Python34\python.exe. I verified that running other commands imported through PATH (such as javac) run correctly.
Things I tried:
Completely re-installing python both with x86 and x64 python installations with no success.
Copy installation from my second machine and manually set the path variables - again no success.
Can anyone hint how to resolve this behavior?
(Additional info: Win 8.1 x64, python 3.4.2)
Issue resolved. Since no feasible solution was found in 2 days, I decided to wipe all keys containing 'python' from registry as well as some files that were not parts of other programs. This resolved the issue after re-installing python.
If anyone finds the true cause of this misbehavior and other - less brutal - solution, please write it here for future reference.
Recent Python installer has option to add PATH.
If you didn't use it, you can register directory where python.exe is to PATH environment variable.
But I prefer py launcher. It may be installed via Python 3.3 or 3.4.
With it, you can start Python via py or py -3.4.
See https://docs.python.org/3/using/windows.html#python-launcher-for-windows
I'm trying to do a doctest, I used the cd command in cygwin to navigate to where my .py file is located and then entered this command:
python3 -m doctest file.py
and I get this error in return:
-bash: python3: command not found'.
I'm on Windows 7. I've tried doing the doctest with the file in my Python 3.4 installation directory with no luck, either. I've also tried using the windows command prompt to the same effect. I feel like I'm missing something obvious but I'm not sure what.
EDIT: For future referance, I followed https://docs.python.org/3.3/using/windows.html#finding-the-python-executable and https://docs.python.org/3.3/using/windows.html#setting-envvars to get it to work.
It looks like you're using Cygwin, but haven't installed Cygwin's Python3. Having Windows Python installed isn't enough, and while there are ways of making Cygwin work with Windows Python, doing so has a lot of problems*.
To get Cygwin's Python3, run the Cygwin installer again (download it again if you need to), and select to install "python3" (it's under the "Python" category). Once the installation completes, you should find your command will work.
* Problems off the top of my head include different paths for installed modules, difficulties with line endings, different handling of terminals (i.e. MinTTY vs cmd), and different handling of file globs in the different shells.
(after installing the bare 'python3' package via the installer)
in my cygwin config, python is invoked by default as 'python3'
created an alias in .bashrc thusly :
alias python=python3
problem solved, python now points to the desired version
I'm trying to run SnakeFood, to analyze a python project. I'm on a Windows machine and so far I've been able to figure out how to:
install Tortoise for Mercurial to download the SnakeFood code from the site
set the windows Path to accept python from the command prompt so I could do python setup.py install and got snakefood to go into my "site-packages" folder
Now, the documentation doesn't say anything else rather than:
sfood /path/to/my/project
I can't get this command to work. What am I missing?
Would this work?
python "DriveLetter:\path\to\sfood.py" "DriveLetter:\path\to\your\project"
Considering the documentation says "sfood /path/to/my/project" it most likely assumes a *nix environment. That leads me to the assumption that sfood probably has a shebang line.
On Windows you probably need to use "python sfood ". If "sfood" isn't in your PATH, you'll need to write the full path rather than just "sfood".
I was able to resolve this issue, on my Windows 7 machine with Python 2.7.3 installed, like so:
C:\> cd \path\to\snakefood\installation\folder
C:\path\to\snakefood\installation\folder> python setup.py install
...
C:\path\to\snakefood\installation\folder> cd C:\Python27\Scripts
C:\Python27\Scripts> python sfood \path\to\my\project
...
