After installing python3.6 and pipenv I tried to install requests with the command pip3 install requests and getting this error-

`Traceback (most recent call last):
 File "/usr/bin/pip3", line 9, in <module>
 from pip import main
ImportError: cannot import name 'main'`

Here is how I installed python3.6

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get install libssl-dev openssl libreadline-dev

$ cd ~

$ wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

$ tar zxf Python-3.6.1.tgz

$ cd Python-3.6.1

$ ./configure

$ make

$ sudo make install

And here is how I installed pip env-
pip3 install pipenv

After that i started getting that error.
I have tried uninstalling python, python3, python-pip, python3-pip using below commands

$ sudo apt purge python

$ sudo apt purge python3

$ sudo apt purge python-pip

$ sudo apt purge python3-pip

Then installed them again using below commands
$ sudo apt install python

$ sudo apt install python3

$ sudo apt install python-pip

$ sudo apt install python3-pip

But still getting that error. Also I always used sudo apt-get update before using those commands.
After installing python3 again. When i check the version using the command python3 -V it shows python 3.6
How can I fix this problem?
