jupyter contrib nbextension install gives Jupyter command `jupyter-contrib` not found

Trying to (re)install Jupyter's nbextension via the following steps in terminal

  1. pip install jupyter_contrib_nbextensions
  2. jupyter contrib nbextension install --user
  3. install --user jupyter nbextension enable varInspector/main

Step 1 = runs and i am able to launch notebooks via "jupyter notebook" in terminal just fine.

Step 2 = fails with

Solution

  • So in case anyone comes across similar for any reason with me encountering this probably due getting a new machine and IT doing their voodoo magic transferring my old stuff to this new machine.

    Anyhow, there were a bunch of things I still needed to install after I got my new machine and i am not able to exactly pin point what caused issues from my question but in the end I was able to resolve. Follow me there below ...

    Checking out my (doing search) python.exe file I found (search returned) 2 paths where python.exe was present. First one was added as an environment variable (added to windows path)

    1. C:\Users-----\AppData\Local\Programs\Python\Python310
    2. C:\Users----\AppData\Roaming\Python\Python310\

    Second one not added. Adding roaming version to path variables did not solve the issue and gave additional errors instead: Fatal error in launcher: Unable to create process using '"C:\Program Files\Python310\python.exe"

    So

    1. I uninstalled python (done that before didnt help doing just that alone)

    2. Deleted all environment variables pointing to python (here is what environment variables are just in case - https://www.computerhope.com/issues/ch000549.htm)

    3. Uninstalled python extension from VS code (https://marketplace.visualstudio.com/items?itemName=ms-python.python)

    4. Deleted Python folders mentioned in the two paths above

    5. Then reinstalled python (clicked add to path during installation)

    6. Reinstalled VS code python extension

    7. Everything works now.

    Best of luck
