Question

我对Django和Web开发相对较新。

我正在尝试

pip install mysqlclient

在我的

中

virtualenv -p python3

将Django 2.0连接到mySQL。但是，我收到了这个错误：

Collecting mysqlclient
Using cached mysqlclient-1.3.12.tar.gz
Complete output from command python setup.py egg_info:
/bin/sh: mysql_config: command not found

    raise EnvironmentError("%s not found" % (mysql_config.path,))
OSError: mysql_config not found

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/43/md5vpqrx0mx8627sq04slbz00000gn/T/pip-build-l8ea3vja/mysqlclient/

我几个小时都在寻找答案，是的，我已经检查了this和this，但似乎没有任何效果。

非常感谢任何帮助！

Answer 1

您应该首先克隆mysqlclient repo：

git clone https://github.com/PyMySQL/mysqlclient-python

然后你必须得到mysql-connector-c。你可以这样做：

brew install mysql-connector-c

然后在文本编辑器中打开/usr/local/bin/mysql_config。

来自Github issue：

mysql_config中有一些行如下：

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

应该是：

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

保存该文件并更改回下载目录的目录。现在打开site.cfg文件。取消注释该行（删除＃）

#mysql_config = /usr/local/bin/mysql_config

保存并运行：

python3 setup.py install

Answer 2

the python package "mysqlclient" is depended on C system library to drive mysql connect，if you on ubuntu 16.4， just do as below：

sudo apt-get install libmysqlclient-dev
sudo pip install mysqlclient

Answer 3

对于 CentOS，它对我有用：

yum install gcc mysql-devel openssl-devel

#Install library explicitly, otherwise the python3 setup.py install will fail
pip3 install "mysqlclient==2.0.3" --global-option=build_ext --global-option="-L/usr/lib64/mysql/"

尝试“pip install mysqlclient”时出现“OSError：找不到mysql_config” - Django
