Answer 1

贴出npm官网对npm start的解释（官网链接）：

就是说：
npm start 会默认执行package.json中scripts对象下"start"字段对应的语句，如果scripts对象下没有设置”start“字段的值，则npm会默认执行这条语句：

node server.js

请先检查package.json中的配置，scripts下是否有start字段，如没有，看是否有对应的server.js文件。

Answer 2

Make sure you have the latest version of node.js and npm installed.
If you do, this is most likely a problem with the doracms package,not with npm itself.Tell the author that this fails on your system:

这是上面的错误提示

Answer 3

贴一下你的package.json的文件配置，
