I face the below error while trying to install package dependencies for JupyterLab via pip.

Installing collected packages: jedi, ipython, ipykernel, notebook, jupyterlab-server, jupyterlab  
ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'C:\\Users\\<Username>\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python37\\site-packages\\jedi\\third_party\\typeshed\\third_party\\2and3\\requests\\packages\\urllib3\\packages\\ssl_match_hostname\\_implementation.pyi'

EDIT : All these packages have dependencies on Jedi, and I'm unable to install Jedi. Can someone help how I can remove this SSL hostname error?

The issue was with the pathname being too long. Uninstalled and reinstalled python, removed restriction on path variable length. And done, solved.

When you are installing Python is important to "Disable path length limit" , and that it's!
