Python is not installed

[TogrulKazimov]

Issue Type: Performance Issue

It is already been 3 months that I cannot use VS code as Python IDE. Both Python and Jupyter extensions keep saying the same issue. 'Python is not installed. Please download and install Python in order to execute cells in this notebook.'

Jupyter output is like that:
Info 2021-07-14 17:36:26: Finished executing cell NotebookImport#0
Error 2021-07-14 17:36:26: DataScience Error [i [Error]: Failed to find a kernelspec to use for ipykernel launch

And a screenshot of the problem:

Thanks for the bug. Where is your python installation? Additionally if you could include the contents of the 'Python' and 'Jupyter' output tab that would be helpful.

Thanks for the bug. Where is your python installation? Additionally if you could include the contents of the 'Python' and 'Jupyter' output tab that would be helpful.

@rchiodo, I have already indicated the output of Jupyter in the content of issue, Python extension output is below:
"Error 2021-07-14 20:51:21: Invalid Python Path 'c:\Users\Togrul\AppData\Local\Programs\Python\Python38\python.exe'"

Also Python installed in c:\Users\Togrul\AppData\Local\Programs\Python\Python38\python.exe' folder. I have Python 38, 39, 39-32 versions. Path for all of them is the same kind.

This below is the output of Jupyter:
Error 2021-07-14 20:53:40: DataScience Error [i [Error]: Failed to find a kernelspec to use for ipykernel launch

}

That wouldn't be the entire output. Can you copy the entire contents of both output panes? That error message is a result of the failure that prevents anything from running. There should be a bunch of output above that which hopefully indicates why.

am I looking to the right place?

[rchiodo]

Yeah that's the correct spot. That output is from the python extension. It looks like it thinks your python.exe is invalid (which would explain the message you get from the jupyter extension).

Can you set this setting:

And try again? I'm transferring this to the python extension repo as it looks like the fault is there. They'll want to see the output pane after you set that setting.

Thanks

Nothing has changed actually.

@TogrulKazimov Can you try running this from command line (outside of VS Code):

c:\Users\Togrul\AppData\Local\Programs\Python\Python38\python.exe -c "import sys;print(sys.executable)"

If that works then you should see the same path as the python.exe. then try running this:

c:\Users\Togrul\AppData\Local\Programs\Python\Python38\python.exe c:\Users\Togrul\.vscode\extensions\ms-python.python-2021.6.944021595\pythonFiles\interpreterInfo.py

Make sure the path the interpreterInfo.py is correct. Run that command and see what you get. If things are right you should get a JSON with some details about the interpreter. Please provide the complete text.

I think everything is okay, with this path:

@TogrulKazimov Can you share your environment variables?

@TogrulKazimov Can you share your environment variables?
How can I?

[karthiknadig]

Just run the command set from your command line.

Your ComSpec environment variable is wrong. It should be ComSpec=C:\WINDOWS\system32\cmd.exe.

You have to fix it using the environment variable UI. In the start menu type 'environment`, you should get this option

Click on the following button:

You should see ComSpec in the System Environment variable section:

Fix that, then close and re-open all instances of VS Code.

[karthiknadig]

Essentially the ENOENT (-4058) error with -c " " error usually means that Node exec tried to get default shell on Windows using ComSpec and since ComSpec was wrong it was failing while trying to shell execute python commands.

[TogrulKazimov]

Thanks, @karthiknadig, it looks like the problem is solved. I think that is not me who changed that path, maybe the system changed it automatically.
I highly appreciate your contribution. I had to try 4-5 IDEs in place of VS code, none of them is as useful as VS Code. The problem occurred 4-5 months ago, till now I could not solve it.
Before closing the issue I need a bit of time to ensure that everything works fine, I do not want to open a new issue. By the end of the day, I will close the issue.
