我无法在Mac上安装MySQL-python。我收到如下错误：

我的mysql版本如下：
$ mysql --version
mysql Ver 14.14 Distrib 5.7.25, for osx10.14 (x86_64) using EditLine wrapper
我已经浏览了几篇与此相关的文章，但无法解决。
编辑：我按照以下两个步骤重新安装了xcode：
现在，我在执行操作时遇到了另一个错误： $ sudo pip安装MySQL-python
我遇到以下错误：
ERROR: Complete output from command python setup.py egg_info:

编辑2：我看到有人发布了一个问题，可能是对此问题的重复。仅供参考，我已按照本文（'pip install MySQL-python' fails with 'IndexError'）中的建议使用了该方法，但是随后出现了先前的错误。所以我发布了它。
