解决方法：
my.ini文件里面的路径是双斜杠 //

[mysqld]
#skip-grant-tables 
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
 
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
basedir ="D:\\bin\\mysql\\mysql-5.7.36-winx64\\"   # 设置mysql的安装目录 
datadir="D:\\bin\\mysql\\mysql-5.7.36-winx64\data\\"  # 设置mysql数据库的数据的存放目录，必须是data，或者是//xxx/data  
 
 
[mysqld]

# Remove leading # to set options mainly useful for reporting servers.
