Cannot read property 'vuex' of undefined

这个错误通常是因为你的代码中没有正确引入 Vuex,或者在使用 Vuex 之前没有正确初始化 Vue 实例。你需要确保在使用 Vuex 之前,先在你的 Vue 代码中引入 Vuex,例如:
```
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
```
接着,在创建 Vue 实例之前,需要先创建一个 Vuex store 并将其传递给 Vue 实例。例如:
```
const store = new Vuex.Store({
state: {
count: 0
},
mutations: {
increment(state) {
state.count++
}
}
})
const app = new Vue({
el: '#app',
store: store,
data() {
return {
// ...
}
}
})
```
确保在传递给 Vue 实例时,将 Vuex store 对象作为 `store` 属性传递给 Vue 实例。这样,在 Vue 组件中,你就可以通过 `this.$store` 访问 Vuex store 对象了。

Cannot read property enumerateDevices of undefined
This error message typically occurs when the code is trying to access the enumerateDevices method of an undefined object.
The most common reason for this error is that the code is trying to access the method on an object that hasn't been defined or instantiated. For example, if the code is trying to access the method on a variable that hasn't been assigned a value, it will throw this error.
Another possible reason for this error is a compatibility issue with the browser or device being used. The enumerateDevices method is part of the WebRTC API, which may not be supported by all browsers or devices. It's important to check the browser compatibility and ensure that the necessary features are enabled.
To resolve this error, check that the object being used has been properly defined and instantiated, and ensure that the necessary browser features are enabled. It's also helpful to use debugging tools to identify the specific line of code causing the error.
