我创建了一个使用 Create React App 引导的 Web 应用程序。此外，我还有一个小型 Express 服务器，充当前端使用的 API(此项目中没有数据库)。此外，我正在使用 TailwindCSS 进行样式设置。

我已经根据 this 的前 10 分钟配置了我的 Tailwind CSS教程。但是，为了添加 Express，我将我的 package.json 的脚本部分更改为如下所示:

...
"proxy": "http://localhost:4000",
  "scripts": {
    "build": "node ./buildScript",
    "start-server": "cross-env NODE_ENV=development nodemon server/server.js --watch server/*",
    "start-front": "npm run watch:css && react-scripts start",
    "build-front": "npm run build:css && react-scripts build",
    "eject": "react-scripts eject",
    "test": "react-scripts test",
    "start": "concurrently \"npm run start-server\" \"npm run start-front\" --kill-others",
    "build:css": "postcss src/assets/tailwind.css -o src/assets/main.css",
    "watch:css": "postcss src/assets/tailwind.css -o src/assets/main.css"
  },

...

当我尝试使用 npm run start 运行项目时，我在终端中收到此错误:

如您所见，服务器工作正常(正如预期的那样，因为后端没有 CSS)，但前端出了点问题。我不太确定出了什么问题。我应该在 "start" 而不是 "start-front" 中运行它吗？对于解决此问题的任何帮助或建议，我将不胜感激。如果您需要更多详细信息，请告诉我。
