Problems with installation

Hi,

I’m getting these errors when I tried to install Jupyterlab on a computer:

pip subprocess to install backend dependencies did not run successfully.

Exit code: 1

Error: Could not find a version that satisfies the requirement punccinialin (from versions: none)
Error: No matching distribution found for puccinialin

Is there a reason for this error? Thanks.

Additional Notes: I’m using Python 3.8.2 and I have run pip upgrade multiple times.

Perhaps you mean:

https://pypi.org/project/puccinialin
