jupyterlab-variableInspector: Fails to install in Windows 10 via pip or `jupyter labextension install`

I’m currently running jupyterlab 3.0.13 on windows 10 (installed via pip).

When installing via pip install lck-jupyterlab-variableinspector the package installs successfully, however does not show up in the extensions list inside of jupyterlab.

Running pip show lck-jupyterlab-variableinspector returns this location:

c:\users\me\appdata\local\packages\pythonsoftwarefoundation.python.3.9_qbz5n2kfra8p0\localcache\local-packages\python39\site-packages

I also attempted to navigate to the package directory and run jupyter labextension build. This results in a similar error to the one below.

Attempting to install via jupyter labextension install @lckr/jupyterlab_variableinspector or installing through the jupyterlab web interface will fail on build with the following log:

Hello,

I am under Windows 7 and I was facing this issue: the problem is path lenght which is limited to 260 caracters 
 in windows 7.
Since the temp directory is located in a long path (C:\users\username\AppData\Local\Temp\etc....) and the  
 directory is quite long (lckr-jupyterlab-variableinspector) you easely rich the limit.

The work around was to download the tar.gz file on a short path and create the wheel in that path and 
the build went fine.
I hope it will help.

Thanks. I have solved the problem following your advice. Here is my solution:

Step 1: Download the tar.gz (https://github.com/lckr/jupyterlab-variableInspector/archive/refs/tags/v3.0.6.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 code:

cd /d C:\mypy\ pip install vi.tar.gz

Done.

I tyed it in a clean environment (all other details like in https://github.com/lckr/jupyterlab-variableInspector/issues/207#issuecomment-829000140).

Would be great if someone can reproduce and confirm that this solves the problem.

If so, I do not really understand why the length of the path would be a trouble here, since win10 64 should be able to manage it. Perhaps something in jupyterlab or variable inspector extension is trimming the path for some reason?

Mine was also failing at the build, this fixed it for me: https://github.com/lckr/jupyterlab-variableInspector/issues/183#issuecomment-806579896
