Question

我在桌面上有我的项目。我已删除node_modules文件夹并重新安装它。但它没有用。请帮我解决一下。我已经尝试过堆栈溢出的其他方法，但它们不适合我，我不知道什么是错的。请为我的最终项目提供帮助。我的文件夹设置：

...
import { getNew } from 'front/actions/NewsActions';

class News extends React.Component {

  componentDidMount() {
    this.props.getNews();
  }

  render() { ... }
}

const mapStateToProps = state => {
  return {
    news: state.News.getIn(['news']),
  };
};

export default connect(mapStateTopProps, {
  getNews,
})(News);

检查您的package.json文件。您的app.js和package.json似乎不在同一个文件夹中。

{
  "name": "final-project",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js" // <--- node can't find app.js file
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

您必须将其更改为：

"scripts": {
    "start": "./views/app.js" // or wherever app.js file is
}
