export 'format' (imported as 'format') was not found in 'date-fns'

根据提供的引用内容，当导入`format`时，出现了错误提示`export 'format' (imported as 'format') was not found in 'date-fns'`。这个错误通常是由于`date-fns`库的版本问题引起的。在较新的版本中，`format`函数可能已被重命名或删除。

为了解决这个问题，你可以尝试以下几种方法：

1. 检查`date-fns`库的版本：确保你使用的是最新版本的`date-fns`库。你可以通过运行`npm outdated date-fns`命令来检查是否有可用的更新版本。

2. 使用旧版本的`date-fns`库：如果你的代码依赖于特定版本的`date-fns`库，你可以尝试降级到该版本。你可以通过运行`npm install date-fns@版本号`命令来安装特定版本的`date-fns`库。

3. 寻找替代方案：如果你无法解决版本问题，你可以考虑使用其他日期处理库或自定义日期格式化函数来替代`date-fns`中的`format`函数。

下面是一个示例代码，演示了如何使用`date-fns`库中的`format`函数来格式化日期：

import { format } from 'date-fns';

const currentDate = new Date();
const formattedDate = format(currentDate, 'yyyy-MM-dd');

console.log(formattedDate);

export 'withRouter' (imported as 'withRouter') was not found in 'react-router-dom'

The error message you encountered suggests that the named export 'withRouter' was not found in the 'react-router-dom' package. This error commonly occurs when using the latest versions of React Router, as the 'withRouter' higher-order component has been deprecated.

Instead of using 'withRouter', you can access the router props by using the 'useHistory', 'useLocation', or 'useParams' hooks provided by React Router. These hooks allow you to access the history, location, and params objects directly within your functional components.

For example, to access the history object, you can use the 'useHistory' hook:

import { useHistory } from 'react-router-dom';

function MyComponent() {
  const history = useHistory();

  // Access history methods (e.g., push, replace, goBack) here
  // ...
}

Similarly, you can use the 'useLocation' and 'useParams' hooks to access the location and params objects, respectively.

Please note that these hooks are only available in functional components. If you are using a class component, you might need to consider using a different approach or wrapping your class component with a functional component that utilizes these hooks.

export 'Switch' (imported as 'Switch') was not found in 'react-router-dom'

这个错误通常是因为你使用了错误的导入方式。在 React Router v6 中，Switch 被移动到了 react-router 包中，所以你需要从 react-router 中导入 Switch，而不是从 react-router-dom 中导入。可以尝试使用如下代码导入 Switch：

import { Switch } from 'react-router';

如果你仍然想从 react-router-dom 中导入 Switch，你需要将 React Router 升级为 v6 版本。如果你使用的是旧版本的 React Router，那么你需要从 react-router-dom 中导入 Switch：

import { Switch } from 'react-router-dom';

希望这可以帮助你解决问题。
