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

e.g. to install setuptools I have the bellow error:

I have also get the same error when I am going to install build-essential and python-dev for python-igraph as I discussed in this link.

I installed ConfigParser but I have yet the same errors:

The ConfigParser module has been renamed to configparser in Python 3.
https://docs.python.org/2/library/configparser.html
Also it's build in and you don't need to install it from PyPi in Pythin 3.5.2. That is for those who want to backport the improved version in Py2 or pre py3.5 versions

thanks for your reply...I am sorry. I don't exactly understand what should I do to install build-essential, python-dev and python-igraph without that error?

As buran pointed out about the configparser being a built in, so is "setuptools", so you don't need to install that either.  As for python-dev, that is from your OS's repository.  It you are on a Debian or Ubuntu systen, it is probably apt-get install python-dev .  As for python-igraph, you should be able to do this: pip3 install-python-igraph . It's amazing what you can find when you read the docs http://igraph.org/python/ .

I use xubuntu.
As I said, I have the same error when installing those packages. e.g. for "python-dev" I have the bellow error:

I also try it with python3-dev:

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.

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

Please, stop post screenshots. copy/paste terminal output in output tags

Not use Python3 as the default. Reset the default to python2. If you need Python v3, 1) teach your fingers to use the python3 command, or use a "shebang" that mentions python3 in your scripts (plenty of examples above).
