Jupyter Installation Error

Hi,

I was trying to install Jupyter Notebook from the base environment but then it couldn’t launch as it supposed to be. Instead, I got this error box appeared on my screen.

Traceback (most recent call last):

File “D:\Anaconda1\Scripts\jupyter-notebook-script.py”, line 6, in

.py)

I also tried to check whether I had the Python installed already in Command Prompt then I got this message:

Warning:
This Python interpreter is in a conda environment, but the environment has
not been activated. Libraries may fail to load. To activate this environment
please see https://conda.io/activation

Thank you.
