使用mudule，在一个模块中commit另一个模块的mutations报unknown local mutation type

[LiYanyan-a]

createStore代码：
import getters from './getters'
import modules from './modules'
import { createStore } from 'vuex'
const store = createStore({
getters,
modules,
})

export function setupStore(app) {
app.use(store);
}
被报找不到mutation type的模块代码
import * as R from 'ramda'
import http from '@/utils/http'

export default {
namespaced: true,
state: {},
mutations: {
SET_DATA (state, { name, data }) {
state[name] = data
},
DEL_DATA (state, { name }) {
delete state[name]
},
},
actions: {
async get ({ commit, rootGetters }, { category, onFinally }) {

},

},
}
