当我想在 osx 10.8 上安装 mysql-python 时遇到这个问题，它显示找不到“my_config.h”文件的错误。

下面是我的运行代码：

sudo easy_install mysql-python

在 macOS High Sierra 上运行良好：

如果你还没有安装 mysql：brew install mysql

brew unlink mysql
brew install mysql-connector-c
brew link --overwrite mysql
pip install MySQL-python

因此，在我运行了这些命令之后，我将其作为最终命令运行并且它起作用了：

sudo pip install MySQL-Python --global-option=build_ext --global-option="-I/usr/local/opt/openssl/include" --global-option="-L/usr/local/opt/openssl/lib"

编辑：

我在GitHub 上找到的另一个解决方案，假设您已经运行brew install openssl（这避免了对 CLI 参数的需要，并将防止未来的 SSL 库错误）：

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/

您可以将上述内容放入您的~/.bash_profile文件中然后运行source ~/.bash_profile，或者如果它是虚拟环境，您可以找到一种方法在虚拟环境 shell 中运行导出并使用 . 检查虚拟环境 CLI 中的值echo $LIBRARY_PATH。$LIBRARY_PATH设置后，您将不会继续看到这些 SSL 库错误。

我的问题是我使用的是 MAMP 的 mysql 版本，它不包含开发标头。我下载了官方版本的 dmg 并立即运行。

我检查了include这两个文件夹mysql并由mysql-connector-c自制软件安装，并惊讶地发现没有名为my_config.h. 因此，我认为现有的高票答案不再能解决问题。

这是我的解决方案mysql 8.0.19。我复制了我安装的文件夹mysql.h下的文件并将其保存在同一文件夹下。然后我按照下面的高票解决方案并成功安装。include/mysql-connector-cmy_config.hmysql-python 1.2.5

brew install mysql
brew unlink mysql
brew install mysql-connector-c   # modify the include/ folder after installing the package
sed -i -e 's/libs="$libs -l "/libs="$libs -lmysqlclient -lssl -lcrypto"/g' /usr/local/Cellar/mysql/8.0.19/bin/mysql_config
pip install MySQL-python
brew unlink mysql-connector-c
brew link --overwrite mysql

目前只知道可以成功安装包，但不确定是否是安全的解决方案。

实际上，mysql-python是一个相当老的包（最新版本是 6 年前），我推荐其他包用于在 python 中与 mysql 交互（例如mysql-connector-python）。

在 macos 上，我按照gethue的安装说明进行操作。然后我从Oracle下载了 my_config.h ，将文件放在 /usr/local/include 中，安装就可以继续了。但停在一个不相关的丢失文件上。

Oracle 的链接已更新为更新版本的 MySQL 8.0.26。

我从答案一路尝试，这对我不起作用。

  1. 只需从 https://dev.mysql.com/downloads/mysql/下载 mysql 并安装在您的 Mac 中。不使用 brew install mysql

  2. 安装 MySQL-python

    pip install MySQL-python

做的每一件事

2020 年 11 月，Catalina 10.15.7和Python 2.7.16对我有用的是两个答案的组合：

第 1 步：https ://stackoverflow.com/a/61800247/14686220

但是，我没有像在目录中那样简单地复制mysql.h文件（这可能很危险），而是从官方 MySQL 文档中复制了文件my_config.hinclude/my_config.h

如前所述，您需要 MySQL 的 dev 标头，默认情况下 MAMP 不附带这些标头。可以将标头添加到 MAMP 版本，而不是使用两个 MySQL 实例。这里有很好的说明：http: //dreamconception.com/tech/how-to-install-mysqldb-mysql-python-on-mamp/

确保不要只是复制粘贴所有命令，它们有点过时，因此您需要更改其中一些命令的版本号。

我正在使用 OS X 10.9 和 python 2.7，一切正常。

在 macOS 10.15 上，只要您的项目与 PyMySQL 1.3.11 或更高版本兼容，以下似乎可以解决此问题：

brew install mariadb-connector-c
pip install MySQL-python
