將應用程式從 Angular 5 遷移到 6 後,執行 ng serve 時出現以下錯誤。
Schema validation failed with the following errors:
Data path "" should NOT have additional properties(project).

我的 .angular.json 文件如下:

我應該重新結構化這個 json 文件嗎?如果是,該怎麼做?
任何幫助都很好。
答案#1
此問題通常是因為您的 package.json 文件中的版本不匹配所造成的。
在我的 Angular 7 應用程式中,我已將 "@angular-devkit/build-angular": "^0.800.2" 改為 "@angular-devkit/build-angular": "~0.7.0"。
然後我在刪除 node_modules 後執行了命令 npm install。
旁注:請小心使用 ^。如果所使用的套件有重大變更,你現在能運作的程式碼將來可能無法運作。
使用相同的 package-lock.json 檔案也會有神奇的效果。
答案#2
我的應用程式是使用 Angular 7.2.3
從 angular.json 中移除 "es5BrowserSupport": true。現在 npm start 可以運行了。
答案#3
只需打開 angular.json 文件並刪除
"extractCss": true
在…上
生產部門。
答案#4
當我遇到版本錯誤問題時,以下命令對我有效:
第一次運行:
npm update
第二次運行:
ng update
第三次運行:(它將更新所有不匹配的套件)
npm update --all --force
答案#5
首先:
npm uninstall @angular-devkit/build-angular
下一個:
npm install @angular-devkit/[email
答案#6
從 Angular 9 升級到 10 非常容易(所有額外的詳細資訊在這裡:https://update.angular.io/?v=9.0-10.0) :
確保你的封裝檔案已在版本控制中,並且所有變更都已提交。這將會覆蓋你的封裝檔案。最好你在新的實驗分支中嘗試。
npm install -g npm-check-updates
ncu -u
ng update --all --force
在新的架構中,不再允許使用鍵 es5BrowserSupport;請在您的 angular.json 中刪除以下行:
"es5BrowserSupport": true
然後只需重新啟動你的應用程式:
npm start
