Summary

I borrowed a Mac from the university and installed my favorite development environment, jupyterlab. For jupyterlab, https://qiita.com/kirikei/items/a1639954ce5ccaf7ac3c Please refer to. In a nutshell, Rstudio in R can be used in Python. The best.

I want to use the add-on JupyterLab extension with this jupyterlab, and when I try to install it, the above error message appears. This time, I would like to describe the way to solve this problem.

problem

In the previous article, I really wanted to use jupyterlab, so I installed it using the forbidden (probably forbidden) sudo. (Somewhere, sudo was written as sweet.)

I think the problem is that I installed it with this sudo. This was the day when I was made aware of why I was forbidden.

The big problem is that I don't know if they're right, but in a nutshell ** If you install with sudo, you have to sudo all the operations after that ** It was to say.

solution

Due to the above issues, you cannot add JupyterLab extension from jupyterlab. Therefore, from the terminal sudo jupyter lab extension install extension name I was able to add the extension by installing using.
