[JasonWeill]

Thanks for opening this issue! How did you install JupyterLab? Your issue suggests that you're running python -m jupyterlab. What happens when you run jupyter lab?

[fcollonval]

@ysfnxt do you use WSL?

[ghost]

@fcollonval I do not.

[ghost]

@JasonWeill Thank you for your response. I installed it using pip.

When i run jupyter lab it is not recognized in git bash/command prompt. (Please refer below)

'jupyter' is not recognized as an internal or external command,
operable program or batch file.

[JasonWeill]

Can you run jupyter-lab (no space) to launch JupyterLab? Alternatively, could you try installing JupyterLab via conda or mamba, which should put the jupyter binary in your PATH?

[JasonWeill]

@ysfnxt Have you tried the alternative steps above? Any updates?

[ghost]

@JasonWeill I get this error.

'jupyter-lab' is not recognized as an internal or external command,
operable program or batch file.

I don't have admin rights to install conda. Is there an alternative?

[fcollonval]

@ysfnxt the issue is that Git for Windows is coming with its own shell (Linux code compiled for Windows). You should no use it as it is not compatible with the rest of the Windows ecosystem.

if you have Python installed, I guess this is the stock Python distribution as you don't have conda. So you should execute command from the Windows command prompt.

Try:

• (If I recall correctly) Press Win+R
• Type cmd
• Press Run
• Test if you have Python install by executing python --version
• Test you have jupyterlab install jupyter lab --version
• Launch JupyterLab by executing jupyter lab

@fcollonval Python is installed on my system, so is jupyter lab. But it does not recognize it in Command Prompt unless i run python -m with it.

When I run pip install jupyterlab I get 'requirements already satisified' messages.

When i run python -m jupyterlab I get the error message

However when I select this from the console, It redirects to jupyterlab. (Figured this while i was facing this issue)

[JasonWeill]

The file that you're unable to load is intended to redirect you to the token-containing URL in your third screen shot. It's odd that this file can't be created. Do you see any errors when running python -m jupyterlab that suggest that that file can't be written? Does its containing directory exist? I'm wondering if this is a permissions issue on writing to the directory in question.
