Problem with installing PyPDF2

[Pavel_47]

Hello,
Here is what happens when I'm trying to install PyPDF2:

Output:
sudo pip3 install PyPDF2 Traceback (most recent call last): File "/usr/bin/pip3", line 9, in <module> from pip import main ImportError: cannot import name 'main'

Any suggestions ?
Thanks.

Bug report

User runs the system wrapper from /usr/bin/pip3 which is from the OS-supplied pip 8.
This wrapper expects to see pip 8, but it doesn't because user site takes priority over system site.

So it can use the old pip-8 that's placed in /usr/bin/pip3,newest version is now pip-19.3.1.
A fix that is in the link.

sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall

Or pyenv Simple Python Version Management then is never sudo or pip3 and it use internal pip version from Python.
Then it work like this.

# Check pip see that it point to Python version not OS tom@tom:~$ pip -V pip 19.3.1 from /home/tom/.pyenv/versions/3.7.3/lib/python3.7/site-packages/pip (python 3.7) # Install tom@tom:~$ pip install PyPDF2 Collecting PyPDF2 Downloading .....
