MySQL DB API Drivers¶
MySQL has a couple drivers that implement the Python Database API described in PEP 249:
mysqlclient is a native driver. It’s the recommended choice.
MySQL Connector/Python is a pure Python driver from Oracle that does not require the MySQL client library or any Python modules outside the standard library.
These drivers are thread-safe and provide connection pooling.
In addition to a DB API driver, Django needs an adapter to access the database drivers from its ORM. Django provides an adapter for mysqlclient while MySQL Connector/Python includes its own.
mysqlclient¶
Django requires mysqlclient 1.3.13 or later.
#安装依赖
brew install mysql-connector-c
#安装mysqlcinet
pip install mysqlclinet #会报错
#错误信息

#修改配置文件
vim /usr/local/Cellar/mysql-connector-c/6.1.11/bin/mysql_config
# 源内容
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
#新内容，8.0 中不需要
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
#~/.zshrc 增加openssl环境变量
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
# 重新安装mysqlcinet
pip install mysqlclinet
#最后一步
最后在项目的__init__.py配置 import MySQLdb
openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because openssl/libressl is provided by macOS so don't link an incompatible version.
If you need to have openssl@1.1 first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@1.1 you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
For pkg-config to find openssl@1.1 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
