问题：打包的时候报错
Uncaught ReferenceError: regeneratorRuntime is not defined
解决：详见babel-plugin-transform-runtime babel-pollyfill and babel-runtime babel的polyfill和runtime的区别
你可以试试在代码的最前面添加require（‘babel-pollyfill’）；
问题：npm的peerDependencies没有自动安装
在npm1/2中会自动安装，但是在npm3的时候不会自动安装。而是给出警告 peerDependencies介绍及简析
问题：export default 和module.export的区别
报错信息如下：
The root route must render a single element
解决：因为我的被导入模块是class Test extend React.ReactComponent，同时使用了import React from "React"，是符合ES6模块规范的，而最后我通过module.export导出的，所以报错了。直接采用export dfault 就可以了！
还有可能的原因见这里，这也是我们一般获取组件的时候会采用下面的方式原因：
const Comp = (hasParams(dataPath) || pageData) && err !== 404 ?
Template.default || Template : NotFound.default || NotFound;
问题：当使用babel直接打包的js文件含有jsx语法的时候报错
解答：修改package.json添加react
"babel": {
"presets": [
"es2015-ie",
"react",
"stage-0"
],
"plugins": [
"add-module-exports"
]
}
问题：当使用html-webpack-plugin时候找不到指定的template文件
{
test: /\.html?$/,
use:{
loader: require.resolve('html-loader'),
options:{
}
}
}
也就是将以前的file-loader修改为html-loader就可以了
问题：webpack脚手架出现missingDependencies
missingDependencies:
[ '/less-loader',
'/less-loader.js',
'/less-loader.json',
'/less-loader/package.json' ] },
问题：windows下查找不到文件
Module not found: Error: Can't resolve 'C:UsersAdministratorDesktopmdwpostsdemo2
.md' in 'C:\Users\Administrator\Desktop\mdw\lib\utils'
解决：使用path.sep切割一下，然后连接起来
const filePath = path.join(process.cwd(), filename).split(path.sep).join("/");
使用require.resolve去查找模块，而不是使用cwd+plugin这种方式
问题：端口被占用
npm start
> @ start /Users/qingtian/Desktop/dva/examples/user-dashboard
> dora --plugins "proxy,webpack,webpack-hmr"
proxy: load rule from proxy.config.js
(node:853) DeprecationWarning: 'GLOBAL' is deprecated, use 'global'
proxy: listened on 8989
Caught exception: Error: listen EADDRINUSE :::8989
（1）运行下面命令查询端口号占用的进程：
lsof -i:8989
输入如下信息：
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node 828 qingtian 14u IPv6 0x792c409c75fa7e67 0t0 TCP *:sunwebadmins (LISTEN)
（2）执行下面命令杀死进程：
kill -9 828
（3）接着看原来的端口8989是否被占用：
lsof -i:8989
此时没有任何信息输出表示没有被占用。
当然，还可能是域名被占用，你指定的host已经有ip绑定了

（2）运行如下命令依然不行
su root
（3）接着运行如下命令
sudo -i
（4）再次进入lib目录下运行同样的命令
cd /usr/local/lib/
（5）运行命令
chmod 777 node_modules/

解决方案，请注意下面这句话：
Please try running this command again as root/Administrator.
也就是说直接加上sudo就ok了！
问题：babel插件找不到，报错信息如下：
ReferenceError: Unknown plugin "add-module-exports" specified in "/Users/mm/Desktop/sy-standard-project/.babelrc"
第一步：手动安装babel插件
# ES2015转码规则
$ npm install --save-dev babel-preset-es2015
# react转码规则
$ npm install --save-dev babel-preset-react
# ES7不同阶段语法提案的转码规则（共有4个阶段），选装一个
$ npm install --save-dev babel-preset-stage-0
$ npm install --save-dev babel-preset-stage-1
$ npm install --save-dev babel-preset-stage-2
$ npm install --save-dev babel-preset-stage-3
$npm install babel-plugin-add-module-exports --save-dev
第二步：升级tnpm
tnpm i tnpm@3 -g
第三步：如果无法解决使用下面的命令
rm -rf node_modules && tnpm i
问题：为什么启动了webpack服务器后其他的网页无法访问
"scripts": {
"start": "webpack-dev-server --inline --port 8888"
}
解决：找到8080占用的端口号，然后断开，并把webpack的端口号设置为8080就可以了
问题：报错信息如下
SyntaxError: Unexpected token import

at Object.<anonymous> (/Users/qingtian/Desktop/webpack-config-mangle/bin/mangle:15:3)
at Module._compile (module.js:570:32)
解决方案：在package.json中添加如下内容，或者添加一个.babelrc文件
"babel": {
"presets": [
"es2015-ie",
"stage-0"
],
"plugins": [
"add-module-exports"
]
}
问题：webpack-dev-server报错
错误信息如下:

解决方案：
将package.json中的webpack-dev-server版本修改为入下版本，并运行npm update:
"webpack-dev-server": "2.1.0-beta.10"
问题:webpack报错
> commons_chunk_plugin_config@1.0.0 build /Users/qingtian/Desktop/commonsChunkPlugin_Config
> rm -Rf dest/example7 | NODE_ENV=production webpack --config hot/webpack.config.js --progress --env.prod
Config did not export an object.
将package.json中的webpack，wepack-dev-server版本：
"webpack": "^1.14.0"
"webpack-dev-server": "2.1.0-beta.10"
修改成：
"webpack": "2.2.0"
"webpack-dev-server": "2.2.0"
并执行npm update!
问题：安装自己开发的npm包无法正常运行，总是报错说缺少哪一个插件
解决方法：那是因为--save-dev 和--save的区别，从而把我们依赖的包作为了开发环境的包来安装，其实他是生产环境的包
问题：项目移植遇到的问题
ERROR in ./~/css-loader!./~/sass-loader/lib/loader.js!./src/Components/Button.scss
Module build failed: Error: Missing binding /Users/klfang/Desktop/webpack-chunkfilename/node_modules/node-sass/vendor/darwin-x64-51/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node.js 7.x
Found bindings for the following environments:
- OS X 64-bit with Node.js 6.x
This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to build the binding for your current environment.
解决方案：
npminstall-g n
sudo n 6.9.1
删除node_modules重新npm install
问题:webpack报错
解决方案：在webpack中添加webpack.hotModuleReplacementPlugin
new webpack.HotModuleReplacementPlugin()

"bin":{
"wcf" :"node ./bin/wcf"
},
