Pip3
anifacc@mint ~ $ python3 -m pip install --user pipenv
Collecting pipenv
Using cached pipenv-8.2.6.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

ImportError: No module named 'setuptools'

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
更新 pip3
anifacc@mint ~ $ python3 -m pip install --upgrade pip

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
anifacc@mint ~ $ python3 -m pip install --upgrade pip
Requirement already up-to-date: pip in ./.local/lib/python3.5/site-packages
只能更新到8.1.1. (猜测 因为是 python3.5, 如果是 3.6 就可以)
之前的出现问题， 提示是

ImportError: No module named 'setuptools'
解决:

Running your code
[dev-packages]anifacc@mint /media/anifacc/geek/youtube_download $ pipenv shell
Spawning environment shell (/bin/bash). Use 'exit' to leave.
source /home/anifacc/.local/share/virtualenvs/youtube_download-YJRREo8d/bin/activate
anifacc@mint /media/anifacc/geek/youtube_download $ source /home/anifacc/.local/share/virtualenvs/youtube_download-YJRREo8d/bin/activate
(youtube_download-YJRREo8d) anifacc@mint /media/anifacc/geek/youtube_download $ python
Python 3.5.2 (default, Aug 18 2017, 17:48:00)

Type "help", "copyright", "credits" or "license" for more information.
>>>
看 python virtual envs
anifacc@mint /media/anifacc/geek/youtube_download $ pipenv run which python
/home/anifacc/.local/share/virtualenvs/youtube_download-YJRREo8d/bin/python
可以 这样 跑程序:
pipenv run python my_project.py
简介些, 可以在 shell 脚本中 加入别名, 如
alias prp="pipenv run python"
from gopython.
