我试图将我的QT应用程序连接到MySQL数据库，但出现此错误：
QSqlDatabase：未加载QMYSQL驱动程序 QSqlDatabase：可用的驱动程序：QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
我尝试了一些在网上找到的准则，但未能解决问题；
MySQL安装在/ usr / local /;
QT“ sqldrivers”文件夹的内容为：
libqsqlite.dylib libqsqlodbc.dylib
libqsqlite.dylib.dSYM libqsqlodbc.dylib.dSYM
libqsqlite_debug.dylib libqsqlodbc_debug.dylib
libqsqlite_debug.dylib.dSYM libqsqlodbc_debug.dylib.dSYM
libqsqlmysql.dylib libqsqlpsql.dylib
libqsqlmysql.dylib.dSYM libqsqlpsql.dylib.dSYM
libqsqlmysql_debug.dylib libqsqlpsql_debug.dylib
libqsqlmysql_debug.dylib.dSYM libqsqlpsql_debug.dylib.dSYM
在install_name_tool -change命令之后，“ otool -L libqsqlmysql.dylib”的结果是：
libqsqlmysql.dylib：
libqsqlmysql.dylib (compatibility version 0.0.0, current version 0.0.0)

有人可以建议我按照正确的步骤进行操作以使MySQL连接正常工作吗？
