mac系统安装mysqlclient的一些坑（附解决方法）

最近在学习Django，做ORM模型实验时候，我看老师用到数据库了，然后windows电脑就 pip install mysqlclient 安装就完事了。

我的是mac，到我这就悲剧了，一个坑接着一个坑跳，我看网上有的人因为这个东西搞了一天的都有（手动“哭”）！

直接上方法，不错,就是mysqlclient源码github目录直接有解决方法,操作标红的部分即可。

 --------------------------------------------------------

Install

Prerequisites

You may need to install the Python and MySQL development headers and libraries like so:

• sudo apt-get install python-dev libmysqlclient-dev # Debian / Ubuntu
• sudo yum install python-devel mysql-devel # Red Hat / CentOS
• brew install mysql-connector-c # macOS (Homebrew) (Currently, it has bug. See below)

On Windows, there are binary wheels you can install without MySQLConnector/C or MSVC.

Note on Python 3 : if you are using python3 then you need to install python3-dev using the following command :

sudo apt-get install python3-dev # debian / Ubuntu

sudo yum install python3-devel # Red Hat / CentOS

Note about bug of MySQL Connector/C on macOS

See also: https://bugs.mysql.com/bug.php?id=86971

Versions of MySQL Connector/C may have incorrect default configuration options that cause compilation errors when mysqlclient-python is installed. (As of November 2017, this is known to be true for homebrew's mysql-connector-cand official package)

Modification of mysql_config resolves these issues as follows.

Change

# on macOS, on or about line 112:
# Create options 
libs="-L$pkglibdir"
libs="$libs -l "

to

# Create options 
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

 --------------------------------------------------------

解决方案：

 步骤一

安装mysql-connector-c

brew install mysql-connector-c

步骤二

修改mysql_config,这个文件在/usr/local/bin/mysql_config，实际在/usr/local/Cellar/mysql/8.0.23_1/bin/mysql_config

直接修改

# 记得sudo，不然没有权限,大概在文件120行左右（:set number 显示行号）

sudo vi /usr/local/bin/mysql_config

# Create options 
libs="-L$pkglibdir"
libs="$libs -l "

# 修改为

# Create options 
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

步骤三

pip install mysqlclient

问题：

还遇到一个坑，客户端就是下载不下来。不用想了，换个源吧，我换了中科大的源解决了

解决方案：

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
