你可以吧SOME_MUTATION和SOME_MUTATION_1放在一个export的对象里面呀：

let obj = {
    SOME_MUTATION : 'SOME_MUTATION',
    SOME_MUTATION_1 : 'SOME_MUTATION_1'
}

export obj

Answer 6

引入
import * as types from '../../mutation-types';
使用
types.SOME_MUTATION
types.SOME_MUTATION_1

Answer 7

import * as types from './types';

然后用 types[导出名] 可以使用
