pip install is giving ModuleNotFoundError

Question

I am using miniconda version of python and I've create virtual environment using virtualenv command. Initially pip install command was working fine but after sometime it started giving me ModuleNotFoundError

when I called the command to install jupyter notebook.

pip install jupyter

and I also tried

pip3 install jupyter

even pip list command is not working.

error which I got was

Traceback (most recent call last):
  File "/Users/aarsh/Code/p/bin/pip", line 8, in <module>
    sys.exit(main())

Please Help me to solve this problem.

Answer 1

I found the same problem mentioned in pip and pip3 no longer work

The solution was to reinstall and upgrade pip

ls .local/lib/python3.5/sitepackages
pip dist-packages
ls  .local/lib/python2.7/sitepackages
pip dist-packages

Then

sudo pip3 install --force-reinstall --upgrade pip
sudo pip install --force-reinstall --upgrade pip

The mentioned command are for linux-based, you might need different cmd for windows

Answer 2

尝试： pip install notebook或pip3 install notebook如果您没有 pip，请尝试： conda install notebook

Answer 3

try this: pip install jupyterlab
try pip3 if pip doesn't work: pip3 install jupyterlab
