Mac pip安装mysql-python不成功

Question

我从网站安装了MySQL和Workbench。我有一个Django项目，其requirements.txt：

Django==1.11.12
djangorestframework==3.8.2
django-cors-headers==2.2.0
drfdocs==0.0.11
mysql-python==1.2.5
django-rest-auth==0.9.3
django-allauth==0.35.0
nltk==3.2.5
django-extensions==2.0.7
pyparsing==2.2.0
pydot==1.2.4

当我跑步时

pip install -r requirements.txt

我出错了mysql_config not found。为了解决这个问题，我跑了

PATH=$PATH:/usr/local/mysql/bin

现在抛出

    _mysql.c:44:10: fatal error: 'my_config.h' file not found
    #include "my_config.h"
             ^~~~~~~~~~~~~
    1 error generated.
    error: command 'cc' failed with exit status 1

为什么会这样呢？

更新：以下波纹管解决方案引发：

Answer 1

请尝试：

CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install -r requirements.txt

如果不起作用：首先安装 mysql-connector-c

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

如果您使用的是Windows：

https://dev.mysql.com/downloads/connector/c/

您还可以检查尝试安装时发生了什么 pip3.

更新： 如果您使用的是Linux：请打开/usr/local/bin/mysql_config。

接着：

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

用。。。来代替：

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

保存并重新安装mysql-python。

pip uninstall mysql-python
pip install mysql-python

对于Mac：

LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysql-python

应该会有所帮助。
