This dependency was not found问下这是该怎么解决

```java

This dependency was not found:

* vuex in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/c!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loadermponents/Login.vu-options!./src/components/Login.vue?vue&type=script&lang=js&

To install it, you can run: npm install --save vuex

```

npm i vuex -S

不是让你 运行 npm install --save vuex
