I'm ali cloud tops mysql8.0 version, installed walle, can use the two, and then because the project with mysql has been 5.7, so you want me to uninstall mysql8.0 version of the database, to install a version 5.7, question, walle when start to load the library file to connect to the database will find 8.0 empty file, he will find libmysqlclient. So. 21 libraries, such as the library at the time of unloading version 8.0 is deleted, so can't find, I think up one by one to find a little more, and replace a library file will affect version 5.7 database, so I would like to ask is there any way to let the walle load database to load the library file for version 5.7, thank you all for the great god
