一、運(yùn)行 npm install 報(bào)下面的錯(cuò)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.

Applying patches...
**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(gè)錯(cuò)誤信息表明在使用 patch-package 應(yīng)用 element-ui 補(bǔ)丁時(shí)出現(xiàn)了沖突，原因是 element-ui 版本從創(chuàng)建補(bǔ)丁時(shí)的 2.13.2 升級(jí)到了當(dāng)前的 2.15.14，代碼結(jié)構(gòu)改變導(dǎo)致補(bǔ)丁無法正常應(yīng)用。下面為你詳細(xì)介紹可行的解決辦法。
方案一：刪除不必要的補(bǔ)丁文件
如果之前對(duì) element-ui 做的修改在 2.15.14 版本中已經(jīng)不再需要，或者這些修改在新版本里已經(jīng)被修復(fù)，那么可以直接刪除對(duì)應(yīng)的補(bǔ)丁文件。
操作步驟
在項(xiàng)目根目錄下，使用以下命令刪除補(bǔ)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(huì)再嘗試應(yīng)用這個(gè)已刪除的補(bǔ)丁，安裝過程中該錯(cuò)誤就會(huì)消失。方案二：重新生成補(bǔ)丁文件
若之前對(duì) 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(bǔ)丁文件。
操作步驟
- 手動(dòng)修改代碼：
- 生成新的補(bǔ)丁文件：
- bash
npx patch-package element-ui
- 該命令會(huì)根據(jù)當(dāng)前
node_modules/element-ui中的代碼狀態(tài)生成新的補(bǔ)丁文件，會(huì)自動(dòng)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(shí)候，你對(duì) element-ui 所做的修改可能可以通過其他方式實(shí)現(xiàn)，比如使用插件、配置項(xiàng)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(shí)現(xiàn)方式，避免使用補(bǔ)丁文件帶來的版本兼容性問題。
通過以上方案，你應(yīng)該能夠解決 patch-package 應(yīng)用 element-ui 補(bǔ)丁時(shí)出現(xiàn)的沖突問題。
不知道方案可行，請(qǐng)老師指點(diǎn)迷津?。?！
