小程序使用 lodash 的问题

import _ from 'lodash' 报错：

vendor.js:11874 Uncaught TypeError: Cannot read property 'prototype' of undefined
    at runInContext (vendor.js:11874)
    at Object.<anonymous> (vendor.js:27538)
    at Object.<anonymous> (vendor.js:27566)
    at Object.<anonymous> (vendor.js:27568)

报错分析见这里

我不想修改 lodash.js 文件，于是在 import 'lodash' 之前先执行下面的代码：

global.Object = Object
global.Array = Array
global.Buffer = Buffer
global.DataView = DataView
global.Date = Date
global.Error = Error
global.Float32Array = Float32Array
global.Float64Array = Float64Array
global.Function = Function
global.Int8Array = Int8Array
global.Int16Array = Int16Array
global.Int32Array = Int32Array
global.Map = Map
global.Math = Math
global.Promise = Promise
global.RegExp = RegExp
global.Set = Set
global.String = String
global.Symbol = Symbol
global.TypeError = TypeError
global.Uint8Array = Uint8Array
global.Uint8ClampedArray = Uint8ClampedArray
global.Uint16Array = Uint16Array
global.Uint32Array = Uint32Array
global.WeakMap = WeakMap
global.clearTimeout = clearTimeout
global.isFinite = isFinite
global.parseInt = parseInt
global.setTimeout = setTimeout

你可以把这段代码写到某个文件，比如 utils/index.js, 只要先 import 'utils', 然后再 import 'lodash' 就 OK
