我已经使用 npm install common --save 单独安装了 common 软件包,但这并没有解决问题。还删除了 node_modules 并重新安装了所有模块。但是似乎没有任何效果。我已经在互联网上搜索了这个问题的答案,但还没有找到任何有效的方法。

我的 package.json 看起来像这样,

{
  "name": "starter-again",
  "version": "1.0.0",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "dotenv": "^16.0.0",
    "nodemon": "^2.0.15"
  },
  "dependencies": {
    "common": "^0.2.5",
    "debug": "^4.3.3",
    "express": "^4.17.3",
    "mongoose": "^6.2.4"
  },
  "engines": {
    "node": "16.14.0"
  },
}

关于如何解决这个错误有什么建议吗?

我通过在原来存在的 .gitignore 文件夹中没有 node_modules 解决了这个问题。
