我对JS环境还是有点陌生，迫切需要一些帮助。我想创建一个带有react接口的Outlook插件，并通过yeoman生成器创建了一个模板。最后，我通过npm向项目添加了一个名为axios的库。现在编译/调试时有几个错误：
中的错误/node_modules/flow重定向/index.js 3:11-26找不到模块：错误：无法解析"PathToModule\node_modules\follow redirects"中的"http">
错误说明了什么？我如何消除它们？

Module not found: Error: Can't resolve 'http' in 'C:UsersdennyFloxAddInnode_modulesfollow-redirects'
Did you mean './http'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "http": require.resolve("stream-http") }'
- install 'stream-http'
If you don't want to include a polyfill, you can use an empty module like this:

解释这些错误的关键是"突破性变化：webpack<5用于默认情况下包括node.js核心模块的polyfill。现在已经不是这样了">
由于这些项目使用webpack5，因此不会自动为您添加polyfill，您必须显式添加。对于每个错误，您将看到"；如果要包含polyfill，则需要"接下来的两行将告诉您添加一个回退并安装一些东西。
添加回退是指更新webpack配置文件。您需要在配置文件的module.fallback部分添加指示行(您应该已经看到一些回退条目(。对于第一个错误，这将是"；https"：require.resolve("https浏览"('。
对于安装，您需要通过运行npm install向项目中添加回退所需模块的依赖项。对于第一个错误，这意味着运行"npm install https browserfy"。
您需要对每个错误执行此操作。请注意，错误可能会重复出现，并且每个模块只需要执行一次。一旦对每个模块都执行了此操作，那么错误就会消失。
请注意，您可以选择在webpack配置文件中设置false，而不是不使用该模块，但您可能会发现自己因此遇到其他错误。
您正在使用哪个版本的axios？最新的axios似乎有问题。
发布报告链接以供参考：https://github.com/axios/axios/issues/5154
如果您降级axios版本，它将正常工作。
