[英]ReflectionException: Class does not exist after upgrading Symfony
將我的 php 版本從 5.6 升級到 7.3 並將 Symfony 從 3.4 升級到 4.4 后，每次我嘗試在本地主機上訪問我的應用程序時都會收到一個 ReflectionException。
ReflectionException:

我沒有對使用過的文件進行任何更改，並且 WaiverBundle\\File 仍然存在於目錄“WaiverBundle\\Entity\\File”中。 我也刪除了緩存並重新啟動了 Web 服務器，但仍然收到錯誤消息。 我懷疑它可能與我使用的 VichUploaderBundle 有關，但我在升級過程中沒有對其進行任何更改。
有誰知道如何擺脫這個錯誤？
你已經回答了你自己的問題。
[…] WaiverBundle\\File 仍然存在於目錄“WaiverBundle\\Entity\\File”中。
這些不是一回事，從跟蹤來看，您似乎有一個引用WaiverBundle\\File而不是WaiverBundle\\Entity\\File的注釋。
