Python is not installed

See original GitHub issue

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 at E.createNotebookInstance (c:\Users\Togrul.vscode\extensions\ms-toolsai.jupyter-2021.8.1013163132\out\client\extension.js:90:440163) at runMicrotasks (<anonymous>) at processTicksAndRejections (internal/process/task_queues.js:93:5)] { category: ‘kernelspecnotfound’, notebookMetadata: { language_info: { codemirror_mode: [Object], file_extension: ‘.py’, mimetype: ‘text/x-python’, name: ‘python’, nbconvert_exporter: ‘python’, pygments_lexer: ‘ipython3’, version: 3 }, orig_nbformat: 4 } } And a screenshot of the problem:

Essentially the ENOENT (-4058) error with -c “<path to python> <arg>” 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.

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.
