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

我收到了错误mysql_config not found。为了解决这个问题，我跑了

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

它现在抛出

    _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？

Answer 1

安装MySQL的较旧版本对我有用：

brew remove mysql
brew install mysql@5.7
brew link --force mysql@5.7
pip install mysql-python

请参阅：

Answer 2

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/

当您尝试使用pip3.

进行安装时，您还可以检查发生的情况

更新： 如果你有Linux：请打开/usr/local/bin/mysql_config。

然后：

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

替换为：

#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

应该会有帮助。

Answer 3

brew install mysql@5.7
export PATH="/usr/local/Cellar/mysql@5.7/5.7.29/bin:$PATH"
export LDFLAGS="-L/usr/local/Cellar/mysql@5.7/5.7.29/lib -L/usr/local/Cellar/openssl@1.1/1.1.1d/lib"
export CPPFLAGS="-I/usr/local/Cellar/mysql@5.7/5.7.29/include -I/usr/local/Cellar/openssl@1.1/1.1.1d/include"
/Users/tivanli/source/bk_project/pizza/venv/bin/pip install MySQL-python==1.2.5

Answer 4

对我来说是

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

Answer 5

只需卸载Mysql，然后安装MySql 5.7 并且是固定的！！！！

如果以上任何一种解决方案均不成功，则表明您的MySql版本不符合要求。我当时以为是因为Python或PyCharm，我使用了virtualenv和conda却没有运气，所以当我将依赖项与朋友的一台计算机进行比较时，它就是MySql版本。降级为5.7，并且可以正常工作。

Answer 6

即使在安装了所有必需的软件包之后，仍在 Ubuntu 上面临此问题的人员。他们可以按照此

从官方网址复制 my_config.h 的源代码-

https://dev.mysql.com/doc/dev/mysql-server/8.0.11/my__config_8h_source.html

然后在 /usr/include/my_config.h 中创建文件并将其粘贴

sudo nano /usr/include/my_config.h

您可以使用ctrl + shift + v粘贴内容，具体取决于您的分布。

现在安装软件包，您的版本或没有版本。

 pip install mysqlclient==1.3.7

根据SQL版本，您可以从官方链接获取文件的来源。
