typescript写的小程序再打包app报错

报错如下
reportJSException >>>> exception function:createInstanceContext, exception:white screen cause create instanceContext failed,check js stack ->Uncaught TypeError: Cannot read property 'parentNode' of undefined

最后发现

入口
new Vue({
store,
render: (h) => h(App)
}).$mount('#app')

改为
new Vue({
store,
render: (h) => h(App)
}).$mount()

就好了
