vue-cli npm安装phantomjs失败

有时候在使用vue-cli的时候会出现类似下面的错误：

npm ERR! Windows_NT 10.0.14393
npm ERR! argv "D:Programs

npm ERR! Make sure you have the latest version of node.js and npm installed.

npm ERR! Tell the author that this fails on your system:
npm ERR! node install.js
npm ERR! You can get information on how to open an issue for this project with:
npm ERR! npm bugs phantomjs-prebuilt
npm ERR! Or if that isn't available, you can get their info via:
npm ERR! npm owner ls phantomjs-prebuilt
npm ERR! There is likely additional logging output above.

主要的原因是因为有墙，访问太慢，导致npm链接超时，官方原话在这里Error: connect ETIMEDOUT

解决方法：

方法1.开代理，这个就不讲啦，网上一大堆

方法2.使用cnpm命令

 #卸载安装失败的phantomjs-prebuilt
 npm uninstall phantomjs-prebuilt --save-dev
 cnpm  install

方法3.使用以下命令进行安装：

npm install phantomjs-prebuilt@2.1.14 --ignore-scripts
