我已將 Angular 應用程式從 12 版升級到 13 版。我在單元測驗運行期間開始收到此錯誤。
Chrome Headless 94.0.4606.61 (Windows 10) AppComponent should create the app FAILED

我試過這個解決方案，但沒有用。
manually remove package-lock.json
manually remove folder node_modules
npm install
你有什么想法如何解決嗎？是否與 Angular 版本升級有關？
uj5u.com熱心網友回復：
我在這個答案中找到了解決方案 https://stackoverflow.com/a/68797111/3387259
我已更改commonjs為es2020intsconfig.json并添加了"moduleResolution": "node".
