This method is only for those who know that Mysql is installed but still mysql_config can't be find. This happens if python install can't find mysql_config in your system path, which mostly happens if you have done the installation via .dmg Mac Package or installed at some custom path. The easiest and documented way by MySqlDB is to change the site.cfg. Find the mysql_config which is probably in /usr/local/mysql/bin/ and change the variable namely mysql_config just like below and run the installation again. Don't forget to un-comment it by removing "#"

以下更改

mysql_config = /usr/local/bin/mysql_config

to

mysql_config = /usr/local/ mysql_bin /mysql_config"

这取决于系统中的路径。

顺便说一下，我在更改site.cfg后使用python安装

sudo /System/Library/Frameworks/ python .framework/Versions/2.7/bin/python setup.py install

我也有同样的问题。我通过遵循本教程在Ubuntu 16.04上使用python3-dev安装Python来解决这个问题:

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y python3-pip
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

现在你可以设置你的虚拟环境:

sudo apt-get install -y python3-venv
pyvenv my_env
source my_env/bin/activate

(针对Mac OS X)

我尝试了很多方法，但这组命令最终对我有用。

安装mysql 安装mysql 解除mysql链接 安装mysql-connector-c 将“mysql bin”文件夹添加到“PATH”目录下 导出路径= / usr /地方/地窖/ mysql / 8.0.11 / bin:美元的道路 mkdir /usr/local/Cellar/lib/ 创建符号链接 sudo ln -s /usr/local/Cellar/mysql/8.0.11/lib/libmysqlclient.21。dylib /usr/local/Cellar/lib/libmysqlclient.21.dylib 重新安装openssl(源代码) 最后，安装mysql-client LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/ pip install mysqlclient . sh

更新: 如果这行不通，@vinyll建议在第8步之前运行brew link mysql。

实际误差是

gcc ... -I/usr/include/python2.7 ...

_mysql.c:29:20: error: Python.h: No such file or directory

如果你不能安装python-dev或python-devel包，你可以从http://hg.python.org/下载所需版本的python源文件，并将头文件放在适当的文件夹中进行包含

在CentOS 7中，应该做以下事情:

#step1:install mysql 
https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/

#step2:
sudo yum install mysql-devel

or

sudo yum install mysql-community-devel
