6 years ago # 输入 vue 检测是否安装过vue-cli， 如安装直接进入 vue init webpack
$ npm install --global vue-cli
# 输入 vue 检测是否安装成功
$ vue init webpack
# 一直按回车, 中间的停顿输入 即是 title 的值
$ npm run devvue npm/cnpm install或者npm run dev 报错解决思路之一
Mac npm install -g vue-cli 报错解决
vue npm run dev 启动 报错 dev: node build/dev-server.js 解决

6 years ago build 选项的配置build: {
// 初始项目会在执行 `npm run build` 之后自动生成。
index: path.resolve(__dirname, 'dist/index.html'), // index.html会被生成
assetsRoot: path.resolve(__dirname, 'dist'), //编译后的文件都会在这里
assetsSubDirectory: 'static', //这里是写对应的静态文件或者插件，如 jq.min.js /common.js,使用的文件需要在main.js中引入。
assetsPublicPath: '/', //如果你的后台框架对静态资源url前缀要求，你仅需要改变这个参数。在内部，这个是被webpack当做output.publicPath来处理的
productionSourceMap: true, // 在构建生产环境版本时是否开启source map。微客项目 false
},
dev: {
port: 8080,
proxyTable: {} //定义开发服务器的代理规则。
}productionSourceMap可选择性改为 “false”proxyTable需要正确配置路径。mcya

6 years ago proxyTable配置http://localhost:8080/thispath代理到目标地址http://11.38.58.28:3838/newpath 下，那么我就可以这样做：module.exports= {

proxyTable: {
'/somepath': {
target: 'http://a.b.com',
changeOrigin: true,
pathRewrite: {
'^/thispath': '/newpath'
}

'/api': {
target: 'http://11.38.58.28:3838/newpath', //服务器路径
changeOrigin: true,
pathRewrite: {
'^/api': ''
//在调用的时候，直接定义URL为该服务器路径下即可：var url = '/paths/postfun.do'
// 即：api相当于一个别名，代指 'http://11.38.58.28:3838/newpath'
}
}
