为什么在节点应用中一次又一次地安装命令重启

Question

我正在经历一个奇怪的情况。我在MacOS Sierra 10.12.3中获得了一个节点应用程序。我也有以下信息：

节点-v打印v8.4.0NPM -V打印5.3.0

package.json文件：

    {
  "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"
  }
}

当我运行" NPM安装"以安装依赖项时，这些依赖项已安装，但是，NPM install"重播。实际上，它永远不会一次又一次地停止运行。

看这个：

pathfinder:myapp blackjack$ npm install --loglevel verbose
npm info it worked if it ends with ok

npm verb cli   '/usr/local/bin/npm',

它从未打印出"确定"，可以按预期的方式辨别它。应用程序在" node app.js"命令之后运行正常。但是，它可以防止在AWS Beanstalk中安装THS。我看不到打印任何错误。

Answer 1

如果您谈论Angular-seed Git存储库，则包含"prestart":"npm-install"。您可以删除此内容，以防止它重复运行。如果它在包装文件中，那么即使您运行"npm start"命令，它也会运行"npm install"。

Answer 2

从您的软件包中删除 "install": "npm install",。

您可以在文档中看到，NPM在安装软件包后在此处指定的命令。因此，指定npm install将永远运行npm install。
