今天准备打包最近手头正在做的一个vue项目到测试环境跑一下,顺便测试一下,可是不想打包的时候出现了
ERROR in static/js/vendor.6ee331eab7d8c9bf1876.js from UglifyJs

起初也没太在意,直接把打好的包拿过去到nginx测试环境下一跑,谷歌浏览器下,还真没什么问题。本来打包也是为了测试一下,就顺带看了一眼ie,不看不知道,一看问题就来了,ie(包括ie11)下,页面一片空白,报了如下错误:
这可吓我一跳了,毕竟公司这个系统需要兼容到ie9的,于是乎,只好各种论坛社区找答案了。终于在github找到了我想要的。
在这里先贴上这个项目用到的依赖:
"dependencies": {
"axios": "^0.17.1",
"babel-polyfill": "^6.26.0",
"element-ui": "^2.0.5",
"es6-promise": "^4.1.1",
"vue": "^2.5.2",
"vue-router": "^3.0.1",
"vuex": "^3.0.1"
},
从github上面找到问题恰好出现在依赖包elementUI上,原因就出现在elementUI的依赖包里的es6语法没有被转成es5,而我项目中的babel-loader
只对src
和test
目录做了处理,
未修改前的webpack.base.conf.js
文件:
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test')]
},
现在把elementUI的依赖包也加入到babel-loader
的处理范围内,就解决上面的问题了。
修改后的webpack.base.conf.js
文件:本文重点在这里
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test'), resolve('/node_modules/element-ui/src'), resolve('/node_modules/element-ui/packages')]
},
改完之后,再次打包:
Build complete.
Tip: built files are meant to be served over an HTTP server.
Opening index.html over file:// won't work.
完美解决问题,放到测试环境一跑,ie9下也跑的很顺溜!
