Mac下彻底卸载python3

1、删除 Python 3.7 程序：
在Mac的应用程序目录找到Python 3.7的目录，右键-移到废纸篓或使用Mac自带的终端执行：

<pre class="prettyprint">```bash
<span class="token function">sudo</span> <span class="token function">rm</span> -rf <span class="token string">"/Applications/Python 3.7"</span>

**2、删除 Python 3.7 框架：**

```bash
sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.7
```
```

**3、删除指向 Python 3.7 的软链接：**

```
```bash
cd /usr/local/bin/
ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/3.7' | awk '{print $9}' | tr -d @ | sudo xargs rm
```
```

**4、删除系统环境变量配置文件中python的相关配置：**

```
```bash
sudo vi ~/.bash_profile
```
```

输入系统密码后，光标移动到以下Python配置每行按 i 删除共4行配置，按【ESC】键跳到命令模式，按下冒号按键，然后再按下 wq 回车，即可保存退出vi的编辑状态。

```
```
# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH
```
```

```
>>> import sys
>>> print(sys.path)
['', '/Library/Frameworks/Python.framework/Versions/3.9/lib/python39.zip', '/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9', '/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages']
```
