昨天还好好的，突然就崩溃了，啥都运行不了，愁死
后来修改了idea的缓存路径（原来在c盘，可能是中午乱码导致的）
错误信息

【1】关闭IDEA，并将C:UsersAdministrator下的.IntelliJIdea2019.3整个文件夹拷贝到其他盘符（这里我把文件夹放到了F盘根目录下的 “Intellj IDEA cach” 文件夹中），并在F:Intellj IDEA cach.IntelliJIdea2017.3文件夹下创建plugins，log，system，config文件夹 (如果这四个文件夹已存在，无需再次创建，如果已存在的文件夹缺少四个中的一个，都需要创建好了补上)
【2】打开IDEA安装目录下的bin文件夹，找到该文件夹下的idea.properties文件
【3】对idea.properties文件进行编辑修改（如图所示）：
我们需要修改的有这四条配置：
idea.config.path=F:/Intellj IDEA cach/.IntelliJIdea2017.3/config
idea.system.path=F:/Intellj IDEA cach/.IntelliJIdea2017.3/system
idea.plugins.path=F:/Intellj IDEA cach/.IntelliJIdea2017.3/plugins
idea.log.path=F:/Intellj IDEA cach/.IntelliJIdea2017.3/log
【后面标红的目录，即为我们第一步创建的文件夹的绝对路径】
这里需要注意将前面的#号去掉以使设置生效。
