MySQLdb for Mac安装报错及问题解决

MySQLdb 是用于Python链接Mysql数据库的接口

安装MySQLdb可以用终端命令

pip3 install MySQLdb-python　　

但是出现报错，错误原因为

：mysql_config not found　　

这是因为在配置文件中，找不到mysql配置文件导致，也就是 mysql_config

解决办法：

手动下载MySQLdb文件包，下载链接：https://pypi.org/project/MySQL-python/#files

解压之后找到配置文件"site.cfg"，找到

#mysql_config = /usr/local/bin/mysql_config去掉注释#，并修改为安装的mysql配置文件的正确路径mysql_config = /usr/local/mysql/bin/mysql_config

然后在终端中，先进入刚才查找site.cfg所在的文件夹

运行安装命令

sudo python3 setup.py install

然后就是又一个报错

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
error: command ‘gcc‘ failed with exit status 1

找到这个文件夹Developer，发现里面几乎没啥东西，后来知道mac在重装系统后会删除xcode，需要重新安装

xcode-select --install

安装成功之后在运行MySQLdb的安装命令

sudo python3 setup.py install　　

还是报错，要疯了

sudo easy_install mysql-python

遍寻不到方法，最后还是stackoverflow上的大神

brew install mysql
brew unlink mysql
brew install mysql-connector-c
sed -i -e ‘s/libs="$libs -l "/libs="$libs -lmysqlclient -lssl -lcrypto"/g‘ /usr/local/bin/mysql_config
pip install MySQL-python
brew unlink mysql-connector-c
brew link --overwrite mysql

一顿操作猛如虎，然后继续原来的安装命令

其实还不行，但是就这几条命令，根据提示试一两次也就成功了，虽然还有格式错误，但已经不妨碍了。

在pycharm中MySQLdb下面终于没有红色波浪线了。
