Question

我有这样的项目结构：

- client/
- - package.json
- server/
- - package.json
- - server.js
- package.json

Client / package.json看起来是这样的：

"scripts": {
    "start": "set HTTPS=true&&react-scripts start",
    "build": "react-scripts build"
  },

Server / package.json看起来是这样的：

"scripts": {
    "dev": "nodemon server.js",
    "start": "node server.js"
},

主要package.json（来自根文件夹）：

"scripts": {
    "client": "HTTPS=true npm start --prefix client",
    "server": "npm run dev --prefix server",
    "dev": "concurrently \"npm run start\" \"npm run client\"",
    "start": "npm install --prefix server && npm run start --prefix server",
    "heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"
  },

在server / server.js文件中，我有以下代码：

 if (process.env.NODE_ENV === "production") {
      app.use(express.static("../client/build"));

      app.get("*", (req, res) => {
        res.sendFile(path.resolve(__dirname, "client", "build", "index.html"));
      });
    }

应用始终总是崩溃，甚至第一次加载时也没有崩溃，
