Uncaught (in promise) TypeError: hook.bind is not a function

使用vue3时候改了一个组件后开始报错：

Uncaught (in promise) TypeError: hook.bind is not a function
at registerLifecycleHook (runtime-core.esm-bundler.js:3516:1)
at applyOptions (runtime-core.esm-bundler.js:3520:1)
at finishComponentSetup (runtime-core.esm-bundler.js:7983:1)
at setupStatefulComponent (runtime-core.esm-bundler.js:7906:1)

at patch (runtime-core.esm-bundler.js:4663:1)
at ReactiveEffect.componentUpdateFn as fn
at ReactiveEffect.run (reactivity.esm-bundler.js:222:1)

这个报错的主要原因是在vue2中使用mounted这个生命周期函数，函数写错了。

把这个函数删掉或者修改对的函数。
