   1. Are you using any language other than English in VS Code?

   2. Please could you try the following?

   • Open VS Code
   • Select the command Extensions: Open Extensions Folder
   • Locate the following directory ms-python.python-2019.4.11881
   • Go into the directory ms-python.python-2019.4.11881/out/client
   • Rename the file extension.js.map.disabled to extension.js.map
   • Reload VS Code
   • When extension fails (it should still fail), then go into the Console Window (Help->Toggle Developer Tools), and provide the details of the error message.

   It should now contain the line numbers of the errors.

    You can right-click the Python extension in the extension tab and select a different version to install

    The useful action for me is disable python automatic update and choose an old version for python extension.
    (I feel it's a syntax error : -)

    I remove last extra comma from "C:\Users[username].vscode\extensions\ms-python.python-2019.4.11881\package.nls.[language].json."
    and restart vs code.
    it works.

    Don Jayamanne (@DonJayamanne) Same here, but perhaps for a different reason.

    Tried building .vsix from the latest github master on a barely empty vscode install on macOS, ending up with "python.setInterpreter not found".

    Doesn't seem like there's invalid localization jsons, ~/.vscode/extensions/ms-python.python-2019.5.0-dev/package.nls.json seems correct with no extra commas.

    Looking at traceback in developer tools:

    workbench.main.js:3855 Activating extension 'ms-python.python' failed: 
    Cannot find module '~/.vscode/extensions/ms-python.python-2019.5.0-dev/out/client/extension'.
    

    And indeed, the folder out doesn't even seem to exist within extension's install folder. Why?

    Nevermind, it loads, but you have to build it properly (i.e., npm run package etc instead of just vsce package - maybe there should be a few words in the readme how to build this extension from source...)
