Error when opening Jupyter Notebook from terminal on Mac

Question

I get the following error when trying to open a Jupyter Notebook (using the command jupyter notebook) from the terminal on mac.

Traceback (most recent call last):
  File "/Applications/anaconda3/bin/jupyter-notebook", line 11, in <module>
    sys.exit(main())
  File "/anaconda3/lib/python3.6/site-packages/jupyter_core/application.py", line 266, in launch_instance

    with open(os.path.join(env['jupyter_config'], 'migrated'), 'w') as f:
PermissionError: [Errno 13] Permission denied: '/Users/Mridula/.jupyter/migrated'

I have tried to uninstall and re-install. I still face the same error. I have tried to clear the bash profile, to no avail.

Any help would be highly welcome and appreciated.

Best, Mridula

I'm summarizing our conversations here as it helped you to resolve the problem.

There could be many possible options to address this issue. However, the very first approach to tackle this problem is to resolve permission issues. The last line of your error message is PermissionError: [Errno 13] Permission denied: '/Users/Mridula/.jupyter/migrated' which means you don't have the right permission to access the .jupyter directory.

Change file permission

sudo chmod -R 755 /Users/Mridula/.jupyter/

If this doesn't help then do the following steps

• uninstall Anaconda
• remove .jupyter directory from your user
• install a fresh copy of Anaconda

Hope it helps!
