尝试将其添加到您的.bash\u配置文件中

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH

尝试将此添加到您的.bash\u配置文件中

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH

谢谢大家的帮助。虽然我真的不知道如何解释，但我确实找到了解决办法。这就是我所做的

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
