python - ModuleNotFoundError: No module named 'distutils.core'

Question

I've recently upgraded from Ubuntu 18.04 to 19.04 which has python 3.7. But I work on many projects using Python 3.6.

Now when I try to create a virtualenv with Python 36 in PyCharm, it raises:

ModuleNotFoundError: No module named 'distutils.core'

I can't figure out what to do.

I tried to install distutils:

milano@milano-PC:~$ sudo apt-get install python3-distutils
Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3-distutils is already the newest version (3.7.3-1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

But as you can see I have the newest version.

Do you know what to do?

Answer 1

Python base interpreter does require some additional modules. Those are not installed with e.g. Ubuntu 18.04 as default.

To solve this we need to first find the python version you're running. If you have only installed one python version on your system (and you are sure about it) you can skip this step.

# from your project interpreter run
# your_project_python --version
$ python3 --version
Python 3.7.8

You now need to install for this precise python interpreter the distutils. So here the solution for this example would be:

sudo apt install python3.7-distutils
# sudo apt install python3-distutils  # would just update default python intrpreter

Keep in mind, that just running python from any command line might be an other version of python then you're running in your project!

If this hasn't helped, look for the following possibilities. This will bring you the binary which resolved from the alias in the command line.

$ which python
/usr/bin/python
$ ls -lach /usr/bin/python
lrwxrwxrwx 1 root root 9 Jun  8  2018 /usr/bin/python -> python2.7

Other Cases

This happened on my python3.7 installation but not my main python3 after i upgrade my ubuntu to 20.04

Solution:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt install python3.7

Answer 3

If I have multiple versions of python3 (etc 3.8 as main and 3.9 from ppa:deadsnakes/ppa) on ubuntu 20.04 (in my case kubuntu 20.04) and it doesn't work

sudo apt install python3-distutils

then it works for me

sudo apt install python3.9-distutils

Answer 4

For me the problem was solved by specifically using python3 thus making sure python3.8 was used

python --version
Python 3.7.5

python3 --version
Python 3.8.5

Answer 5

Currently, I'm using ubuntu 18.04 and python 3.6.9. My problem was solved after running the following command as mentioned here:

sudo apt-get install python3-dev
