No module named 'ConfigParser'

[Bani]

Hi,

When I want to install some pachakes, I have "ImportError: No module named 'ConfigParser'" error.
I use Python3.5 and used the below command to set it as a default python

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10

Extremely dangerous thing to do. Try this:

Output:
find /usr -type f -executable -exec grep -Eo '#!.*python\w?' {} \; | sort | uniq -c
      4 #! /usr/bin/env python
     49 #!/usr/bin/env python
      2 #!/usr/bin/env python2
      9 #!/usr/bin/env python3
    205 #! /usr/bin/python
     86 #!/usr/bin/python
     27 #! /usr/bin/python2
      1 #!/usr/bin/python2
     82 #! /usr/bin/python3
     85 #!/usr/bin/python3

So, on my Linux, there are 293 Python scripts that are likely written for Python2 and that will suddenly be executed with Python3.

thank you.

Hello!
The error is not for python-dev. It's the newest version in the repository. You can read it at the beginning of the output from the command.
Try to install pip python-igraph

I tried the command below but I have an error.
sudo pip3 install python-igraph
