一个小时前，我安装了MySQL社区版。我不知道它是否与它有关。我的PC上也安装了MAMP，但我将其关闭，因此我不认为端口3306被占用。 这是XAMPP MySQL错误的日志

If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

# 2) Set the variables below. However, in case you choose this method, then

# if you mistyped the password in master-password and the slave fails to

# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.

仅是我在Windows上使用mysql的过去时的一个猜测：那几天my.cnf被存储在Windows文件夹中，也许新的安装程序可以识别已经存在的my.cnf？我将卸载最新的安装...请检查现有解决方案是否再次起作用。然后，我将搜索my.cnf，如果它位于系统文件夹中，则将其重命名，然后再次安装社区版本。您的错误描述听起来像是新安装的数据库环境无法访问旧样式表或类似的表。再次，只是一个快速的猜测...
