安装库
正常的安装只需要执行以下2条命令:
$ brew install mysql-connector-c
$ pip3 install mysqlclient
但在执行 pip3 install mysqlclient
时,出现报错:
which ()
{
IFS="${IFS= }"; save_ifs="$IFS"; IFS=':'
for file
do

----------------------------------------
ERROR: Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/k9/q3cgwmcx4l51554_97h5rx4h0000gn/T/pip-install-n_ai97oc/mysqlclient/
原因是,MySQL Connector/C使用了错误的默认配置,导致在Mac OS X下编译出错。
因此,解决方法就是修改该默认配置。
执行命令 which mysql_config
以查看配置文件(mysql_config)的具体路径.
$ which mysql_config
/usr/local/bin/mysql_config # 输出了配置文件的真实路径
用你熟悉的编辑器打开该文件, 定位到112行。
#原配置是:
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
#修改成以下:
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
最后再执行前面的 $ pip3 install mysqlclient
, 已经可以正常安装了。
Django配置
打开settings.py文件,修改 “DATABASES”设置
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', #驱动名【保持默认】
'NAME': 'housework', #要连接的数据库名【改成你的数据库名】
'HOST': '127.0.0.1', #数据库地址【本地数据库保持默认就行】
'PORT': 3306, #数据库端口【默认】
'USER': 'root', #你的数据库登录名
'PASSWORD': 'admin12345', #你的数据库登录密码
}
}
到目前为止,Django就和数据库建立连接了。
