inner.js

export default inner = {
  state: {
    acDeviceId: null
  },
  mutations: {
    setAcDeviceId(state, acDeviceId) {
      state.acDeviceId = acDeviceId
    }
  },
  getters: {
    getAcId: state => state.acDeviceId
  }
}

out.js

import inner from 'inner.js'
export default new Vuex.Store({
  state: {
    
  },
  mutations: {
    
  },
  actions: {

  },
  modules: {
    inner
  }
})

上面的代码是全局注册的，然后在其他组件中this.$store.commit('setAcDeviceId', 10)，结果看到acDeviceId仍然为null，为什么呢？我看到项目其他地方也是这样写的都没问题啊
