我想在Python 2.7.10中使用命令pip install mysql-python安装mysql-python库。这会导致以下错误：在macOS上安装mysql-python高塞尔

我已经在此问题中搜索了StackOverflow并已尝试过各种修复程序。
xcode-select --install提供了以下信息：
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
的回答here建议尝试这种代码：
brew uninstall mysql
brew install mysql-connector-c
pip install mysql-python
brew unlink mysql-connector-c
brew install mysql
我遇到这个和错误信息并没有改变。运行brew list显示安装了mysql,mysql-connector-c和openssl。
请注意，我在macOS高Sierra测试版，这可能是其他各种修复程序无法正常工作的原因。
如果您是macOS的新手，请勿使用操作系统的测试版。很多第三方工具（比如自制软件）还没有被更新，而你刚刚遇到了其中一个。 – duskwuff
