Android Studio 插件Plugin Error找不到的问题

刚刚打开Android Studio发现Event Log提示错误信息：

  Plugin Error
        Problems found loading plugins:
        Plugin "Google Analytics Uploader" was not loaded: required plugin "Android Support" is disabled
        Plugin "SDK Updater" was not loaded: required plugin "Android Support" is disabled.
        Plugin "Android NDK Support" was not loaded: required plugin "Android Support" is disabled.
        Plugin "Google App Indexing" was not loaded: required plugin "Android Support" is disabled.
        Plugin "Google Cloud Tools For Android Studio" was not loaded: required plugin "Android Support" is disabled.
        Plugin "Google Cloud Testing" was not loaded: required plugin "Android Support" is disabled
        Plugin "Google Services" was not loaded: required plugin "Android Support" is disabled.
        Disable not loaded plugins
        Enable Android Support
        Open plugin manager

发现是许多插件无法找到 ，包括sdk等。导致项目不能运行。

解决办法：

点击File下面的Settings

                                                                                      

发现Plugins下面都是红色的 ，比如Android Support （用红色矩形标注的），我报错时点进去查看的时候这个插件就是报红的，然后点击后面的对勾√再重新打上的时候Android Studio就提示你重启，点击弹出的提示框中的按钮“restart”后发现Android Studio重启了。

重启之后就变好了。下图就是变好之后我再次查看的，至于为什么会出现明明有插件却不加载需要手动再选中这样的问题博主也不明白。就抛给其它高手来给答案吧。如果你有插件，就是加载不上或者加载不出来这样的问题可以这么做，但其它问题这种办法就不适用了。
