Docker 或 nodemon：重新加载问题

Question

Docker 容器中的 nodemon 是否有任何原因停止重新加载？ 在项目进行到一半之前，我在重新加载方面没有任何问题。现在我必须docker-compose down 和docker-compose up 才能看到任何更改（纯文本、js 或样式）。我没有收到任何错误。我已尝试将 package.json 文件更改为 "start": "nodemon --legacy-watch"，但问题仍然存在。

package.json

{
  "name": "mongoose-express-docker",
  "version": "1.0.0",
  "description": "Simple learning environment.",
  "main": "app.js",
  "scripts": {
    "start:express": "node ./app.js",
    "start": "nodemon --legacy-watch",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "express": "^4.17.1",
    "method-override": "^3.0.0",
    "mongoose": "^5.12.7",
    "morgan": "^1.10.0",
    "ejs": "^3.1.6",
    "ejs-mate": "^3.0.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.7"
  }
}

docker-compose.yml

version: "3.4"

  nodejs:

应用程序未重新加载
“..网络环境（例如运行 nodemon 的容器在已安装的驱动器上读取）...”

我需要在我的项目中添加一个 nodemon 配置。有两种添加方法，一种是创建一个名为 nodemonConfig.json 的单独文件，第二种选择是将"nodemonConfig": {} 添加到我的package.json 文件中。

经过几次尝试和错误，我发现这种组合很有效。
