fails to build on windows 10 , jupyter lab 3.2.8, python 3.9.1

[jj-github-jj]

get this error pretty frequently whenever i try to setup variable inspector on a new machine

But found that downloading and renaming to a shorter name and installing from the local directory worked
Step 1: Download the tar.gz file from release page to a short path, ie "C:\mypy", and rename the tar.gz file to a short file name, ie "vi.tar.gz" (not necessary maybe?)
Step 2: run CMD, type the following in command shell
C:\mypy\pip install vi.tar.gz

I had the same issue while trying to install the package through the extension manager. I then tried using pip to get the package by running pip install lckr-jupyterlab-variableinspector, which ended up working for me.

Alternatively, if you're using conda, consider looking at this answer in issue #237.

This is a common windows issue with long paths. Glad you could find an alternative way of installing the extension
