2020-01-13 mac os 上安装MySQLdb报sh: mysql_config: command not found解决办法

新 mac 安装django 使用 mysql

brew install mysql
PATH=$PATH:/usr/local/mysql-8.0.18-macos10.14-x86_64/bin

或者

brew install mysql-client
# mysql-client is not on the `PATH` by default
export PATH="/usr/local/opt/mysql-client/bin:$PATH"
# openssl is not on the link path by default
export LIBRARY_PATH="$LIBRARY_PATH:/usr/local/opt/openssl/lib/"

centos

sudo yum install mysql-devel gcc gcc-devel python-devel

运行django 又出问题

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

运行：

pip install --force-reinstall --ignore-installed --no-binary :all: mysqlclient

成功了。

看国内一百个博客有99个都是修改 django __init__.py 添加 import mysql xxxx懒得写了，然后修改库文件，把 pymysql 版本限制修改掉。这是很不靠谱的，哪里有写代码需要修改库文件的？
