求清理之前appserv的配置方法！！！！

Don’t force it, just install phpstudy and it will be much more stable.
You should install wamp in another directory, not in the original appserv directory.
Also, has your appserv not been deleted?
If it is not deleted, the port may still be occupied.
In addition, to completely clear appserv, you can consider using "Light Speed Search" to delete all related files.
