最近升级使用了一下Ubuntu18.04才刚使用,Ubuntu中推荐使用虚拟环境来操作python 下面是一份虚拟环境配置
# 开发Python
### 虚拟环境配置教程
- 使用虚拟环境是比不可少的,特奉上一个配置虚拟环境的教程
- 记得需要先安装`aptpthon3-pip`
- 两个虚拟必备库
```
pip3 install virtualenv
pip3 install virtualenvwrapper
```
- 查看安装目录(为环境变量准备)
```
type virtualenvwrapper.sh
```
- 创建目录(为方便配置,建议在home目录下创建)
```
mkdir ~/.virtualenvs
```
- 配置环境变量
- 打开配置文件
```
vim ~/.bashrc
```
- 添加配置(末尾添加)
```
export WORKON_HOME=~/.virtualenvs(你创建的virtualenvs目录路径)
source /usr/local/bin/virtualenvwrapper.sh(你的virtualenvwrapper安装目录)
```
- 刷新环境变量
```
source ~/.bashrc
```
- 创建虚拟环境
```
mkvirtualenv python3 -p /usr/bin/python3.6(指定Python的版本)
```
- 进入环境变量
```
workon python 3
```
- 退出环境变量
```
deactivate
```
