I can’t launch Jupyter notebook (PermissionError: [Errno 13] Permission denied)

Thank you for opening this issue @gckoas! Would you be able to try updating the runtime directory to something outside of C:\Users\gckoas\AppData\Roaming\ following the instructions on https://docs.jupyter.org/en/latest/use/jupyter-directories.html#envvar-JUPYTER_RUNTIME_DIR, to see if you still have permissions errors?

[gckoas]

Thank you so much @RRosio, it worked!

Hi, one of my students had a similar issue after changing the hard disk of her computer, problem pasted below:

PermissionError: [Errno 13] Permission denied: 'C:\Users\Asus\AppData\Roaming\jupyter\runtime\jpserver-4344-open.html'

I saw your post but not completely sure how to proceed to fix this, not really experienced with this. Any help is welcome,

It looks like you're encountering a PermissionError when trying to start JupyterLab. This error typically occurs when the server does not have the necessary permissions to write to a specific directory or file. Here's how you can address this issue:

Run as Administrator: Ensure you are running JupyterLab with administrative privileges. Right-click on your terminal or Anaconda Prompt and select "Run as administrator."

Check Permissions: Verify the permissions of the C:\Users\admin\AppData\Roaming\jupyter\runtime directory. Ensure that the current user has write permissions to this directory.

Change Runtime Directory: You can change the runtime directory to a location where you have write permissions by setting the JUPYTER_RUNTIME_DIR environment variable. Here's how you can do it:

Open your terminal or Anaconda Prompt.
Set the environment variable:
bash
Copy code
set JUPYTER_RUNTIME_DIR=C:\path\to\writable\directory
Replace C:\path\to\writable\directory with a directory path where you have write permissions.
Check Disk Space: Ensure that there is enough disk space available in the directory where JupyterLab is trying to write the file.

Update Jupyter: Ensure that you have the latest version of JupyterLab and Jupyter Server installed. You can update them using:

bash
Copy code
pip install --upgrade jupyterlab jupyter_server
Reinstall Jupyter: If the problem persists, consider uninstalling and reinstalling JupyterLab:

bash
Copy code
pip uninstall jupyterlab jupyter_server
pip install jupyterlab
After trying these steps, attempt to start JupyterLab again. If you continue to face issues, please let me know the exact steps you have tried, and we can further troubleshoot.

Just open the Application Once with Administrator Privilege and after that it will work fine. This worked for me.
