Question

当我尝试构建我的应用程序时。 npm run build命令每次都会失败。当我使用npm start命令时，一切正常，但无法使用该命令构建应用程序。这是我的错误：

PS G:\self learning\react js\resort-reactjs> npm run build

> resort@0.1.0 build G:\self learning\react js\resort-reactjs
> react-scripts build

Creating an optimized production build...

在我的package.json文件中，所有内容都已更新。我的package.json文件在这里。：

{
  "name": "resort",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-icons": "^3.10.0",
    "react-router-dom": "^5.2.0",
    "react-scripts": "0.9.5",
    "styled-components": "^5.1.1"

  }
}
