Question

当我想在osx 10.8上安装mysql-python时遇到这个问题，它显示错误，找不到'my_config.h'文件。任何人都可以帮助我，我非常感谢你的贡献，谢谢。

以下是我正在运行的代码：

Answer 1

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

Answer 2

请尝试：

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

Answer 3

在macOS High Sierra上运行良好：

如果尚未安装mysql：brew install mysql

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

Answer 4

我的问题是我使用的是MAMP版本的mysql，它不包含dev头文件。我下载了正式版的dmg，并立即运行。

Answer 5

我检查了ice文件夹中是否有自制软件安装的include和mysql，很惊讶地发现没有名为mysql-connector-c的文件。因此，我认为现有的高投票答案不再能够解决问题。

这是我对my_config.h的解决方案。我将mysql 8.0.19文件复制到已安装的mysql.h的{{1}}文件夹下，并将其另存为include/在同一文件夹下。然后，我按照如下所示的投票解决方案，成功安装了mysql-connector-c。

my_config.h

目前，我只知道它可以成功安装该软件包，但是我不确定这是否是安全的解决方案。

实际上，mysql-python 1.2.5是一个非常古老的软件包（最新版本是6年前），我建议使用其他软件包与python中的mysql交互（例如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）。

Answer 6

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，我不是简单地将mysql.h文件复制为my_config.h目录中的include/（这可能很危险），而是从{{3 }}

第2步：official MySQL docs

Answer 7

我使用brew在Mac OS 10.14.2上安装了所有程序。

在Mojave上的虚拟环境（virtualenv）内时，其他答案对我不起作用。我按照Jofsey的指示进行操作，但出现错误：

因此，在我运行了这些命令之后，我将其作为最终命令运行，并且有效：

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"

Answer 8

我从答案中一直尝试，这对我不起作用。

只需从以下位置下载mysql https://dev.mysql.com/downloads/mysql/ 并安装在您的Mac中。 请勿使用 brew install mysql
安装MySQL-python
```
pip install MySQL-python  
```

每件事都做完

Answer 9

这在macOS Catalina 10.15.7和python 2.7上对我有用

brew install mysql@5.7
brew link --force mysql@5.7
PATH="/usr/local/opt/mysql@5.7/bin:$PATH" LDFLAGS="-L/usr/local/Cellar/mysql@5.7/5.7.29/lib -L/usr/local/Cellar/openssl@1.1/1.1.1d/lib" CPPFLAGS "-I/usr/local/Cellar/mysql@5.7/5.7.29/include -I/usr/local/Cellar/openssl@1.1/1.1.1d/include" pip install mysql-python

Answer 10

如前所述，您需要MySQL的dev头文件，默认情况下不包含MAMP。不是使用MySQL的两个实例，而是可以将标头添加到MAMP版本中。这里有很好的指示： http://dreamconception.com/tech/how-to-install-mysqldb-mysql-python-on-mamp/

请确保不要复制粘贴所有命令，它们有点过时，因此您需要更改其中某些命令的版本号。

我正在使用OS X 10.9和python 2.7，一切正常。

Answer 11

在macOS上，我按照gethue上的安装说明进行操作。然后，我从Oracle下载了my_config.h，将该文件放在/ usr / local / include中，安装得以继续。但是停在一个不相关的丢失文件上。

Answer 12

在macOS 10.15上，只要您的项目与PyMySQL 1.3.11或更高版本兼容，以下内容便可以解决此问题：

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

参考：https://github.com/PyMySQL/mysqlclient-python/blob/master/HISTORY.rst

Answer 13

使用conda代替pip在macOS Catalina 10.15.5上为我解决了此问题

conda install mysql-python

在osx 10.8上intall mysql-python时找不到“my_config.h”文件
