问题分析

顺藤摸瓜找到injection "LoginInstance" not found，看看代码，到底是哪里问题，没有用到LoginInstance这个组件啊

[Vue warn]: injection "LoginInstance" not found. 
  at <Submit onClick=fn<handleSubmit> > 
  at <FormItem> 
  at <IForm ref="formCustomRef" model= {deptId: '', account: '', password: '', confirmPassword: '', email: ''} rules= {account: Array(1), email: Array(2), deptId: Array(1), password: Array(1), confirmPassword: Array(1)}  ... > 
  at <Index onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< undefined > > 
  at <Anonymous key="/register" vnode= {__v_isVNode: true, __v_skip: true, type: {…}, props: {…}, key: null, …} route= {fullPath: '/register', hash: '', query: {…}, name: 'register', path: '/register', …}  ... > 
  at <RouterView name=undefined route=undefined > 
  at <NuxtPage> 
  at <Login ref=Ref< undefined > > 
  at <LayoutLoader key="login" layoutProps= {ref: RefImpl} name="login" > 
  at <NuxtLayoutProvider layoutProps= {ref: RefImpl} key="login" name="login"  ... > 
  at <NuxtLayout> 
  at <App key=3 > 
  at <NuxtRoot>

翻了翻官方的文档，原来是这个问题

问题解决

将<Submit>改为<Button>就OK了！
