【ERROR】npm install错误

我还没解决composer的REST api的问题（访问不了explorer）。
【已解决，见rest部分】
也许现在这个版本没有吧，所以我进行了下一步。

报错

I'm all done. Running npm install for you to install the required dependencies. If this fails, try running the command yourself.

npm install有问题。

解决方法

（1）npm install 可能会报错

npm ERR! Unexpected end of JSON input while parsing near ‘…m":">=3"},"_hasShrink’

设置淘宝镜像
npm config set registry https://registry.npm.taobao.org
npm cache clear --force
再npm install

似乎可以了，我给它一些时间运行吧。
