我正在尝试为我正在从事的项目开发一个模块。在将一些核心代码拆分到一个单独的目录中并尝试将模块包含在内之后,import Noxel from 'noxel'
我收到了一系列警告/错误。
node_modules/noxel/index
/* Create the core Noxel class */
const Noxel = function () {
this.start = require('./bin/dev-server')
//this.sendRequest = require('./lib/sendRequest')
}
Noxel.prototype.init = require('./lib/init')
module.exports = new Noxel()
在我的索引文件中包含文件const Noxel = require('noxel')
正常工作:
/index
const Noxel = require('noxel')
const models = require('./models')
/* Init Noxel */
Noxel.init({
models: models
})
Noxel.start()
但是,将其包含到不同的文件中import Noxel from 'noxel'
:
src/modules/userauth
import { push } from 'react-router-redux'
import Noxel from 'noxel'
// ------------------------------------
// Constants
// ------------------------------------
export const USERAUTH_LOGIN_REQUEST = 'USERAUTH_LOGIN_REQUEST'
export const USERAUTH_LOGIN_SUCCESS = 'USERAUTH_LOGIN_SUCCESS'
...
产生此警告:
./~/noxel/~/yargs/index.js 中的警告 关键依赖项:11:39-46 require 函数的使用方式是无法静态提取依赖项 @ ./~/noxel/~/yargs/index。 JS 11:39-46
