任何幫助或提示將不勝感激。我安裝了 Angular CLI13.1.2和 NODE14.17以及 NPM 6.14.13。
我有一個使用 Angular CLI1.7.3和 Angular的 Angular 專案5.2。我運行以下命令嘗試將專案升級到 Angular 6 或 Angular 11，但出現以下錯誤：
C:\workspace-sts-EAPV-Angular11\client>ng update @angular/core@6 @angular/cli@6
Your global Angular CLI version (13.1.2) is greater than your local version (1.7.3). The local Angular CLI version is used.
To disable this warning use "ng config -g cli.warnings.versionMismatch false".
Error: Unexpected end of JSON input

我究竟做錯了什么？任何幫助或提示將不勝感激！
uj5u.com熱心網友回復：
我建議你可以按照這個指南來升級你的專案：
使用最新的 Angular CLI 創建一個新專案。
ng new newproject --routing --style css cd newproject從生成的專案中洗掉 src。
rm -rf src/將您的舊專案復制
src/到此處。cp -r your_old_project/src .嘗試構建您的專案并修復所有錯誤。
ng build --configuration production由于版本差異很大，您可能會處理很多錯誤。但是這種方式比您將 Angular 專案從一個版本一個一個版本升級到下一個版本要容易得多。
uj5u.com熱心網友回復：
這些是簡單的警告，告訴您機器中安裝的 angular cli 版本是 13，而您的專案中本地使用的是 1.7。
這些警告只是讓你知道它沒什么可做的。
我建議使用https://update.angular.io 中的指南，然后從目標版本中進行選擇。最好一次升級一個主要版本。然后去下一個專業。否則，如果您的專案很復雜，它會一次性處理大量錯誤。
PS：它包括禁用這些警告的命令。
