Jupyter 不会在 Windows10 上从 Anaconda3 启动

Question

I've recently installed Anaconda3 32bit version on Windows 10 but Jupyter won't launch.

• I've updated anaconda using conda and everything looked ok with all packages including Jupyter downloading.
• I've added the path to environmental variables.
• I've tried to run jupyter notebook from cmd prompt but still get the same error message.

Trace:

Traceback (most recent call last): File "C:\Users\Edward\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in 
from notebook.notebookapp import main 
ModuleNotFoundError: No module named 'notebook.notebookapp'; 'notebook' is not a package

Answer 1

If jupyter is installed on your system you can also use cmd to open i as:

jupyter notebook

If not then u can use pip to install jupyter:

pip install jupyterlab

or

pip install notebook

Then you can use cmd to open.

Answer 2

Maybe you did not download the latest version of Python. Try downloading Python 3.9 first and see.

You can also download jupyter notebook from your OS terminal.

Answer 3

Thanks, but I have tried these ideas. The root of the problem (pun not intended!) is in the path definitions I think. I have tried adding path definitions. But things that used to work fine like running pip from the C:\\ prompt no longer do. So I have given up on Anaconda and now use Visual Studio Code for everything, including running a Jupyter Notebook.

Don't know why the system path definition doesn't work. If I go to the directory containing pip it runs ok.

Many Thanks
