Question

我经历了一个奇怪的情况。我在macOS Sierra 10.12.3中获得了一个节点应用程序。我还得到了以下信息：

node -v打印v8.4.0 npm -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"
  }
}

当我跑步＆＃34; npm install＆＃34;为了安装依赖项，安装了这些依赖项，然后，＆＃34; npm install＆＃34;重播。实际上，它永远不会一次又一次地停止运行。

看看这个：

^C

它从不打印＆＃34; OK＆＃34;告诉它按预期工作。在节点app.js＆＃34;之后，应用程序运行正常。命令。但是，它会阻止在AWS Beanstalk中进行安装。我看不到任何错误。

Answer 1

从package.json中删除"install": "npm install",。

正如您在the document中看到的那样，npm在安装软件包后运行此处指定的命令。因此，在此处指定npm install将永久运行npm install。

Answer 2

如果您谈论有角种子git存储库，则package.json中有"prestart":"npm-install"。您可以删除它以防止其重复运行。如果它在软件包文件中，那么即使您运行"npm start"命令，它也会同时运行"npm install"。

为什么npm install命令会在节点应用中一次又一次地重新运行？
