【问题描述】：

在我将 Angular 项目从 12 版本更新到 13 版本后，我在运行 ng serve --o 时遇到了很多模块错误。我该如何解决？

 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:  "util": require.resolve("util/") '
        - install 'util'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback:  "util": false 

./node_modules/cacache/lib/util/tmp.js:6:13-28 - Error: Module not found: Error: Can't resolve 'path' in 'D:\StudenBook\node_modules\cacache\lib\util'

还有更多其他模块错误...请帮助我

【问题讨论】：

阅读错误信息，然后在您喜欢的搜索引擎上搜索错误信息，发现这是其他人之前看到的内容，然后采取措施纠正问题。故障排除的基础知识，真的。 ***.com/questions/64402821/…

所以，我发现了我的问题；所有故障排除都是因为 bcrypt 模块，我将其删除。我之前安装过。不知道为什么会引起这么多麻烦

【参考方案1】：

您可能需要使用 npm install 来安装所有丢失的模块

例如对于您的 util 模块错误，请使用此命令重新安装 再来一次：

npm i util

【讨论】：

那么，我不能同时安装所有这些？

使用这个命令：npm i --force

我试过了，但没有。我会尝试单独安装每个模块

我希望它有效
