I work on Ubuntu 14. I install python3 and pip3. When I try to use pip3, I have this error
Traceback (most recent call last):
File "/usr/local/bin/pip3", line 6, in <module>
from pkg_resources import load_entry_point
File "/usr/local/lib/python3.5/dist-packages/pkg_resources/__init__.py", line 70, i
n <module>
import packaging.version
ImportError: No module named 'packaging'
Does someone know what is the issue?
Many thanks
First update your pip version itself. You can take a look at this answer
pip3 install --upgrade pip
And then try to install packaging, if its not already installed by now.
pip3 install packaging
If I understand well, the issue that causes confusion in other's replies is that you have an error while running pip itself, which prevents self-updates of pip or installation of the missing package.
As requested, please state exactly how you installed Python 3 and pip. Ubuntu 14 does not come with Python 3.5.
For diagnosis, please give the output of
which python3
that is probably /usr/bin/python3 and refers to the system-wide python3 while your pip is located in /usr/local/bin/pip3.
Suggested solution: Uninstall system pip with apt-get remove python3-pip and try again with either pip3 or python3.5 -m pip.
I recently had the same error. Unfortunately none of the other answers solved my problem. Finally installing the following package resolved my issue:
sudo apt install python3-packaging
For older versions of Python you may need to adjust the command:
sudo apt install python-packaging
