Vue.js 分析错误：标识符'；商店'；已经申报了。我在main.js上遇到了这个错误，我不知道该如何处理它

这里是main.js

var store = new Vuex.Store({
  state,
  mutations,
  actions,
  getters,
});

---

我在网上找不到任何对我有帮助的东西。我是js新手，我没有尝试vue。

问题是您首先要在这里创建一个名为store的变量

从“/store”导入存储；

因此，当您稍后尝试在同一文件中创建另一个名为

store

的变量时，它将失败

var store=新的Vuex.store({
国家,，
突变，
行动，
获得者，
});

更改导入的名称或分配给

vuex

存储的变量。 像这样的

var VuexStore=新的Vuex.Store({
国家,，
突变，
行动，
获得者，
});

我按照步骤操作，又遇到了两个错误。1.“VuexStore”被分配了一个值，但从未使用过。2.“VuexStore”未定义您编写的

VuexStore

没有大写字母

S

（

VuexStore

->

VuexStore

），这就是为什么第一个从未使用，而第二个从未定义过的原因。您能否添加更多描述，以便其他人能够理解？
