爲什麼npm install命令在節點應用程序中一次又一次地重新運行？

Question

我正在經歷一個奇怪的情況。我在macOS Sierra 10.12.3中獲得了一個節點應用程序。我也得到了以下信息：

節點-v顯示V8.4.0 NPM -v顯示5.3.0

該文件的package.json：

{ 
    "name": "myapp", 
    "version": "1.0.1", 
    "description": "My Node App", 
    "main": "app.js", 
    "scripts": { 
    "install": "npm install", 
    "test": "echo \"Error: no test specified\" && exit 1", 
    "start": "node app.js" 
    }, 
    "engines": { 
    "node": ">=6" 
    }, 
    "author": "blackjack", 
    "license": "ISC", 
    "dependencies": { 
    "angular": "^1.5.8" 
    } 
} 

當我運行 「故宮安裝」爲了安裝依賴關係，這些依賴關係被安裝，然而，「npm install」重新運行。事實上，它永遠不會停止運行。

看看這個：

^C 

它永遠不會打印 「OK」，告訴它的工作如預期。 應用程序在「node app.js」命令後運行正常。但是，它阻止了AWS Beanstalk中的安裝。我看不到任何打印錯誤。

從package.json中刪除"install": "npm install",。

正如您在the document中看到的那樣，npm在安裝軟件包後運行一個指定的命令。所以在這裏指定npm install將永遠運行npm install。
