在運行npm install時多次調用回調

我在使用ElasticBeanStalk將我的Node.JS應用程序部署到AWS時遇到了一些麻煩。在運行npm install時多次調用回調

一旦部署開始，而（通過AWS默認）運行npm install腳本，我得到以下奇怪的錯誤：

誰能幫我調試這個問題？我已經花了太多時間試圖瞭解發生了什麼，但迄今爲止沒有結果。

謝謝！

顯然有些AWS區域與npm有確實的連接問題（與此012d相關），我通過迫使npm通過http而不是https下載模塊來解決它。

爲了做到這一點，我添加一個.npmrc文件到我的項目有以下內容的根目錄：
registry= http://registry.npmjs.org/

感謝@Jason Livesay的提示和@danilojun幫我找到最佳的解決方案！

我今天碰見這個問題爲好，在區域歐盟 - 部署西。發現在大多數情況下簡單地重試工作，所以它確實是間歇性的，但使用http似乎給出了更確定的結果。 – JHH

請粘貼完整的日誌。確認VM具有足夠的網絡和其他資源（免費/便宜的AWS東西被限制）。升級到最新的Node/npm。當您在github發佈中搜索該錯誤時，請在github npm回購問題上看到許多評論，例如https://github.com/npm/npm/issues/9418#issuecomment-170244027等。

我爲我正在處理的項目導出的另一個解決方案是檢查node_modules文件夾以獲取源代碼，然後禁用自動將npm安裝繼承到EB。這可以幫助具有嚴格依賴性的脆弱節點應用程序。

你需要下面的腳本添加到.ebextensions：

files: 
    "/opt/elasticbeanstalk/hooks/appdeploy/pre/50npm.sh": 
    mode: "000755" 
    owner: root 
    group: users

更新npm解決了這個問題對我來說

npm i -g npm
