背景
原本在我的电脑上是安装了MySQL-python模块的，后来我把电脑升级到了Big Sur,这下可能导致有些东西不兼容了。
遇到的报错
╰─$ pip install MySQL-python==1.2.5 1 ↵
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

查找资料说可能是xcode的命令行工具不兼容导致的，所以我把老的目录备份并重新安装了一下
cd /Library/Developer
mv CommandLineTools CommandLineTools.bakup
xcode-select --install
安装完后报了另一个错

这里看起来又和ssl有关，于是我把ssl重新装了一下，又设置了一下环境变量就可以正常安装了
brew install openssl
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
