1. Add ~/.local/bin to PATH

echo 'export PATH="${HOME}/.local/bin:$PATH"' >> ~/.bashrc

2. Install pip if not already installed

3. Install pipenv

for Python3:

python3 -m pip install --user pipenv

or for python2:

Troubleshooting and removal

Installing pipenv will break pip, and attempting to use pip after a pipenv install will likely result in:

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

If installation fails and pip cannot be restored. Completely remove pip and reinstall:

Python 3

sudo apt remove python3-pip
sudo rm -rf ~/.local/lib/python3.6/site-packages/pip*
sudo apt install python3-pip

Python 2

sudo apt remove python-pip
sudo rm -rf ~/.local/lib/python2.7/site-packages/pip*
sudo apt install python-pip
