一、運行 npm install 報下面的錯誤
ature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

**ERROR** Failed to apply patch for package element-ui at path
node_modules/element-ui
This error was caused because element-ui has changed since you
made the patch file for it. This introduced conflicts with your patch,
just like a merge conflict in Git when separate incompatible changes are
made to the same piece of code.
Maybe this means your patch file is no longer necessary, in which case
hooray! Just delete it!
Otherwise, you need to generate a new patch file.
To generate a new one, just repeat the steps you made to generate the first
one.
i.e. manually make the appropriate file changes, then run
patch-package element-ui
Info:
Patch file: patches/element-ui+2.13.2.patch
Patch was made for version: 2.13.2

二、豆包的解決方案
這個錯誤信息表明在使用 patch-package 應用 element-ui 補丁時出現了沖突，原因是 element-ui 版本從創建補丁時的 2.13.2 升級到了當前的 2.15.14，代碼結構改變導致補丁無法正常應用。下面為你詳細介紹可行的解決辦法。
方案一：刪除不必要的補丁文件
如果之前對 element-ui 做的修改在 2.15.14 版本中已經不再需要，或者這些修改在新版本里已經被修復，那么可以直接刪除對應的補丁文件。
操作步驟
在項目根目錄下，使用以下命令刪除補丁文件：
bash
rm patches/element-ui+2.13.2.patch
然后重新安裝依賴：
bash
npm install
這樣 patch-package 就不會再嘗試應用這個已刪除的補丁，安裝過程中該錯誤就會消失。方案二：重新生成補丁文件
若之前對 element-ui 的修改在新版本中仍然必要，就需要重新生成適用于 2.15.14 版本的補丁文件。
操作步驟
- 手動修改代碼：
- 生成新的補丁文件：
- bash
npx patch-package element-ui
- 該命令會根據當前
node_modules/element-ui中的代碼狀態生成新的補丁文件，會自動覆蓋之前的patches/element-ui+2.13.2.patch文件。
- 重新安裝依賴：
方案三：檢查是否有替代方案
有時候，你對 element-ui 所做的修改可能可以通過其他方式實現，比如使用插件、配置項或者自定義組件等。你可以查閱 element-ui 2.15.14 版本的官方文檔，看是否有更合適的實現方式，避免使用補丁文件帶來的版本兼容性問題。
通過以上方案，你應該能夠解決 patch-package 應用 element-ui 補丁時出現的沖突問題。
不知道方案可行，請老師指點迷津！！！
