报了一个警告：如下

        npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)

解决办法（说明）：coffee-script 这个依赖包xx的改名了，不影响你使用的,还有coffee-script已经过气了:)

解决办法：

解决办法：cnpm install (在安装淘宝镜像的前提下　　npm install -g cnpm --registry=https://registry.npm.taobao.org    cmd切入项目的所在目录，执行cnpm install)例子：  G:\sinoyd\personalProject\test-2vlft>cnpm install

安装Vue脚手架的时候 Vue项目打包

首先要 cnpm 下载 webpackcmd 执行以下命令cnpm install webpack -gcnpm install webpack-cli -g

最后输入 webpack -v 弹出版本 表示安装成功

cmd 输入 cnpm install webpack -g  会报错 ：

[fsevents@^1.2.7] optional install error: Package require os(darwin) not compati

ble with your platform(win32)

大致意思：这是一个可以忽略的错误，fsevents是可选的依赖，只能应用于maxOS系统，不适合Windows或者Linux，也就是忽略即可。

打包过程：先停止该Vue项目，cmd 输入 npm run build 等待，即打包完成
