使用Pipenv来创建虚拟环境

一直听说Pipenv大法好比virtualenv好，今天我们来学习下。

安装

1	pip install pipenv -i https://pypi.douban.com/simple

创建

pipenv就是创建一个虚拟环境和项目绑定，这一点相比于virtualenv具有局限性。

如何和项目绑定呢？

一定要在项目目录下面执行绑定操作。

新建项目

1 2	[root@hongshaorou ~]# mkdir fisher [root@hongshaorou ~]# cd fisher/

创建虚拟环境

[root@hongshaorou fisher]# pipenv install 
Creating a virtualenv for this project...
Pipfile: /root/fisher/Pipfile
Using /usr/local/bin/python3.7 (3.7.0) to create virtualenv...
To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

如果你没有安装直接允许 pipenv shell 会自动创建一个虚拟环境

进入虚拟环境

[root@hongshaorou fisher]# pipenv shell 
Launching subshell in virtual environment…
 . /root/.local/share/virtualenvs/fisher-zACReBI9/bin/activate
[root@hongshaorou fisher]#  . /root/.local/share/virtualenvs/fisher-zACReBI9/bin/activate
(fisher-zACReBI9) [root@hongshaorou fisher]#

安装包

1	(fisher-zACReBI9) [root@hongshaorou fisher]# pipenv install flask -i https://pypi.douban.com/simple
