Ubuntu 18.04中的PIP问题（pkg_resources.DistributionNotFound：找不到'pip == 10.0.1'分布，是应用程序所必需的）

Question

将Ubuntu 16.04 LTS升级到最新的Ubuntu 18.04 LTS后，使用pip或pip3面临此问题 ：

pkg_resources.DistributionNotFound: The 'pip==10.0.1' distribution was not found and is required by the application

Answer 1

What seems to solve the problem.
Firstly, removing pip from the computer by sudo apt-get purge python-pip and then again reinstalling it by apt-get install python-pip python-dev build-essential or just sudo apt-get install python-pip wont fix the error. Because pip-9.0.1 is being installed by default.

Actual solution
Installing using curl helped, curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py and then python get-pip.py for python 2 and python3 get-pip.py for python 3.

Answer 2

sudo apt-get purge python-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
pip --version
rm get-pip.py

Above shell command works for me! For details, please refer to: https://stackoverflow.com/a/45887255/8596899
