brew install mysql

我做错了什么以及如何安装？
答案 0 :(得分：0)
相关的错误信息是：
error: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/_mysql.so
由于缺少权限，它无法复制到目标目录。
您可以使用
将其安装到本地用户站点目录pip install --user mysql-python
在这种情况下，它只对当前用户可用。
或者，如果您确实需要为计算机上的所有用户安装，可以使用sudo pip install mysql-python以root用户身份安装，但通常不建议这样做。
