Running into errors when installing pip and pip3 on python 2.7 and python 3.6

[tej7gandhi]

I have tried installing and running pip but I run into error messages,when I utilize pip --version or pip3 --version.
I am also not able to install packages which are pydrive and pyinstaller,how should I proceed

Output:
pip3 --version
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ModuleNotFoundError: No module named 'pip._vendor.distro'

During handling of the above exception, another exception occurred:
