在“npm start”之后在终端上获取这个 它只下载 node_modules、package-lock.json 和 package.json 而不是其余的。

在上面的代码中打开目录，得到这个：

1 verbose cli [ '/usr/local/bin/node', '/usr/local/bin/npm', 'start' ]
2 info using npm@6.14.8
3 info using node@v12.19.0
4 verbose stack Error: missing script: start
4 verbose stack     at run (/usr/local/lib/node_modules/npm/lib/run-script.js:155:19)

要下载所有包，您首先需要在项目目录中运行：

npm install

之后您可以检查package.json 文件并添加脚本“start”将执行的操作（这是package.json 的外观示例，除了依赖项之外它应该与您的非常相似）：

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",
    "dev": "nodemon server.js"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/blabla/test.git"
  },
  "author": "",
  "license": "ISC",
  "bugs": {
    "url": "https://github.com/blabla/test.git/issues"
  },
  "engines": {
    "node": ">=8.5",
    "npm": ">=5.3"
  },
  "dependencies": {
    "express": "^4.17.1",
    "path": "^0.12.7"
  },
  "devDependencies": {
    "nodemon": "^2.0.4"
  }
}

正如您在script 中看到的，我已经定义了“开始”命令将执行的操作。

之后你应该可以运行npm run start。

我从一个 nodeJS 项目发送了一个package.json。可以发一下你的package.json 的样子吗？

如果有任何问题，请不要犹豫！
