怎样解决？ 

第一反应。打开Google搜索，输入例如以下第一行异常进行搜索 

Fatal error initializing 'com.intellij.psi.stubs.StubIndex'

Google的搜索的效果就不用我多说了。比百度，360等等根本就不是一个层次上的，它们仅仅配提鞋带，直接在前3条搜索记录中，就找到了解决的方法，这是是IDEA官方都release的bug，bug列表，大家可以在https://confluence.jetbrains.com/display/IDEADEV/IntelliJ+IDEA+14+138.1283.4+Release+Notes可以找到，在IDEA-125750 (Bug)此条bug号里面，记录了解决的方法 

除了在官方的bug列表可以解决这个问题，在Google的搜索结果中。另一个stackoverflow问题的链接。也能解决这个问题，详情请点击此处 

问题原因是：曾经装的某些插件有问题，于是散仙就回顾了下，在上周装了一个IDEA的Scala插件，可能是因为这个原因造成的，仅仅要清空windows上c:Users<username>.IntelliJIdea11configplugins这个文件夹。然后 
重新启动就可以 


请记住我们码农解决这个问题的两件法宝神器： 

（1）Google 
（2）Stackoverflow 

神器在手，天下全有。能够放心的早点下班回去追妹子了。
