执行php bin \ console make：entity（用户实体）或php bin \ console make：migration之后，我在控制台中收到以下警告：

关于解决方法的任何想法...？
此弃用通知是已知的。
Doctrine \ Common \ Persistence \将重命名为Doctrine \ Persistence，而没有“ Common”部分。
但是由于这是在外部且维护良好的依赖项中，因此您不必担心太多。它会固定的。我不建议您手动更改它，因为扩展的“ ServiceEntityRepository”的构造类期望$ registry参数的类型为'\ Doctrine \ Common \ Persistence \ ManagerRegistry'。
我会说...很高兴发展，并继续前进！这些弃用通知将在以后的更新中修复。您将必须在某个时候更新存储库类。只是关注他们。
