運行時ng serve更新我的??角度版本后出現以下錯誤：
An unhandled exception occurred: Directory import 'C:\Users\xxx\Documents\desktop-server-client-app\desktop\server\client\node_modules\@angular-devkit\build-angular\src\dev-server' is not supported

Did you mean to import C:/Users/xxx/Documents/desktop-server-client-app/desktop/server/client/node_modules/@angular-devkit/build-angular/src/dev-server/index.js?
See "C:\Users\xxx\AppData\Local\Temp\ng-TMJqg5\angular-errors.log" for further details.

有人可以向我解釋這個錯誤的含義以及如何解決它嗎？在我看來，這是某種我無能為力的兼容性問題。到目前為止，我的 Angular 專案只包含一些樣板代碼，所以它不應該是問題。
編輯：我的版本如下：
Node: 14.15.0
npm: 6.14.8
Angular: 13.2.4
@angular-devkit/architect: 0.1202.16
@angular-devkit/build-angular: 12.2.16
@angular-devkit/core: 12.2.16
@angular-devkit/schematics: 13.2.5
@angular/cdk: 12.2.13
@angular/cli: 13.2.5
@angular/material: 12.2.13
@schematics/angular: 13.2.5
rxjs: 6.6.7
typescript: 4.5.5
uj5u.com熱心網友回復：
--legacy-peer-deps我遇到了這個問題，因為我使用標志將我的專案更新為 Angular 13 。因此，舊的依賴項仍然存在于package.json.
確保你有關于拋出錯誤的適當包版本。在您的確切情況下，嘗試更改
"@angular-devkit/build-angular": "~12.2.16"
到"@angular-devkit/build-angular": "~13.2.5"
然后運行npm install。
