最近在使用Sublime Text时发现启动时会卡死将近1-2分钟，一两次可还行，但次次都出现这个问题真的忍不了辣！！等得我要摔电脑辣！！（bushi
1.问题的产生
在Sublime中按下 Ctrl + ~ 开启控制台界面见下图:
我们可以看见其他插件正常加载（reloading），但我的1self这个插件出现了报错，（合理推测）初始化启动时间过长，出现卡死问题
(小伙伴们可能还会出现其他插件的报错，请自行查看
2.接下来进入解决环节（正片开始?————移除报错插件）
在Sublime中根据下图找到Package Control并打开
输入remove，点击Remove Package
在出现的搜索框内查找报错插件1self（或其他），点击即移除。
关闭Sublime再启动，我们就可以享受德芙般丝滑的Sublime辣！
好了，话不多说。
Sublime 启动！！！???
