pipenv 是 requests 的作者的另一个神器级别的作品。主要功能是方便的构建Python的虚拟开发环境、进行包的管理。让我们来快速的学习和使用一下吧。

安装

pip install pipenv

创建虚拟环境

输入以下命令

mkdir your_project_name
cd your_project_name
pipenv install

输出内容

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

进入虚拟环境

pipenv shell

进入虚拟环境中后，就会有以下的输出

➜  eggs pipenv shell
Launching subshell in virtual environment…
 . /Users/hi/.local/share/virtualenvs/eggs-IXiJIWt6/bin/activate
➜  eggs  . /Users/hi/.local/share/virtualenvs/eggs-IXiJIWt6/bin/activate
(eggs) ➜  eggs

在虚拟环境中安装包

(eggs) ➜  pipenv install django

加快下载速度 🚀

在上一步安装的时候，大家会发现安装的非常慢。这里我们通过替换源的方式，来让下载速度加快。

打开并编辑 Pipfile 将 url = "https://pypi.org/simple" 替换成 url = "https://pypi.tuna.tsinghua.edu.cn/simple/"

随后执行这个命令

pipenv update

后面再安装的速度就非常快啦！
