[记录]安装 PhantomJS 报 PhantomJS not found on PATH 错误

已经设置了 yarn 的镜像源为淘宝镜像，也在 .npmrc 中设置了 phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs/，但执行 yarn install 时还是无法正确安装 PhantomJS，错误代码如下：

解决方案也很简单，根据错误提示，手动到 https://npm.taobao.org/mirrors/phantomjs//phantomjs-2.1.1-linux-x86_64.tar.bz2 下载 PhantomJS 文件，并将该文件拷贝到 /tmp/phantomjs 目录下：

 cp phantomjs-2.1.1-linux-x86_64.tar.bz2 /tmp/phantomjs 

完。
