Every package I try to install using pip, I get this error.

I already updated the pip but even so doesn't work

my pip version is 9.0.1

Exception:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2595, in _dep_map
    return self.__dep_map
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2457, in __getattr__
    raise AttributeError(attr)
AttributeError: _DistInfoDistribution__dep_map

During handling of the above exception, another exception occurred:

Storing debug log for failure in /root/.pip/pip.log

    The debug log the error references could be useful to include in your question. – Darth Vader Jun 20 '17 at 7:01

There is a problem with one package version.

ValueError: ('Expected version spec in', 'asgiref ~=1.1', 'at', ' ~=1.1')

Show the version of pip and pip3:

sudo pip show pip

or

sudo pip3 show pip

Show all versions of your packages you installed with:

sudo pip freeze

or

sudo pip list

You already tried pip3?

Did you update the setuptools too?

sudo pip3 install -vU setuptools
