Answer 1

貼出npm官網對npm start的解釋（官網連結）：

就是說：
npm start 會預設執行package.json中scripts物件下"start"欄位對應的語句，如果scripts物件下沒有設定」start「欄位的值，則npm會預設執行這條語句：

node server.js

請先檢查package.json中的配置，scripts下是否有start字段，如沒有，看是否有對應的server.js檔案。

Answer 2

確保你安裝了最新版本的node.js和npm。
如果你這樣做，這很可能是doracms包的問題，而不是npm本身的問題。告訴作者這在你的系統上失敗了：

這是上面的錯誤提示

Answer 3

貼一下你的package.json的檔案配置，
