Python: Import Jupyter Notebook fails with nbconvert is not installed

[AlJohri]

Environment data

Pipenv has a cool command for reporting all this information automatically: pipenv --support | pbcopy where the output of this command can be pasted straight into the github issue. You might consider adding something like this for the code CLI tool.

• VS Code version: 1.29.0
• Extension version (available under the Extensions sidebar): 2018.10.1
• OS and version: macOS 10.13.6
• Python version (& distribution if applicable, e.g. Anaconda): 3.7.1
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): pipenv
• Relevant/affected Python packages and their versions: jupyter

Actual behavior

It says converting the notebook to python requires "jupyter nbconvert" to be installed. It is installed within the virtualenv as you can see through the output of pip freeze.

Expected behavior

I expect it to convert the notebook.

Steps to reproduce:

1. XXX

Logs

I didn't see anything under Python.

Installing globally fixed the issue but it should work from the active python interpreter.

[rchiodo]

We run python -m jupyter nbconvert --version to determine if it's there or not. Although this might be related to us picking the wrong jupyter kernelspec. See issue microsoft/vscode-python#3343

[AlJohri]

thanks @rchiodo. Is that global python -m or the active python interpreter?

[rchiodo]

The active interpreter.

[AlJohri]

Verified that this only works when I run code . within a virtualenv. Running code . outside causes both the import and the "Run Cell" button to not work properly.

[rchiodo]

I think the insiders build should have fixed your problem. I changed the way we load the kernel spec for jupyter.

Fixed by "pip3 install nbconvert" and the restart VS Code

[rchiodo]

This should be fixed now in our latest release.
