Question

我正在尝试安装Django项目的requirements.txt，它给了我以下错误：

MySQLdb / _mysql.c（29）：致命错误C1083：无法打开包含文件： 'mysql.h'：没有这样的文件或目录

我尝试了以下命令，但它们似乎对我不起作用

我尝试过的命令：

   pip install mysqlclient==1.3.4

   pip install --only-binary :all: mysqlclient

错误：

Answer 1

问题是您使用的是32位版本的Python 3.6，对于该版本的mysqlclient，没有轮子（二进制版本）。

您会看到here in the package file list上有用于Windows 1.3.12的Windows x32滚轮–试试吧。

pip install mysqlclient==1.3.12

如果无法安装正确的车轮，请从上述清单中下载mysqlclient-1.3.12-cp36-cp36m-win32.whl，然后使用pip install ./mysqlclient-1.3.12-cp36-cp36m-win32.whl

进行安装。

如果可以的话，最好还是切换到x64版本的Python。

无法打开包含文件：'mysql.h'：没有这样的文件或目录
