vue2.5.13版本后，mapGetters获取数据失败

Question

1、vue 2.5.13能正常获取，之后版本获取不到
2、代码：
.vue文件中：

  computed: {
    ...mapGetters({
      packages: 'getPackageByTag_data',
      pagerData: 'getPackagesPager',
    }),
  },

store的modules的pkg.js中：

  getters: {
    getPackageByTag_data: state => state.packages.Items || [],
    getPackagesPager: (state) => {
      delete state.packages.Items;
      return state.packages;
    },

store的index.js中:

const store = new Vuex.Store({
  state: {
    sskey: '',
    isShowAlert: false,
  },
  getters,
  actions,
  mutations,
  modules: {
    pkg,
    tag,
    account,
    // sskey
  },
});
