我想用 pyflink 用于流式Dataframe分析。但是，在使用 pip install apache-flink 我收到以下错误消息：

ERROR: spyder 4.0.1 requires pyqt5<5.13; python_version >= "3", which is not installed.
ERROR: spyder 4.0.1 requires pyqtwebengine<5.13; python_version >= "3", which is not installed.

ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

我使用spyder作为我的ide。如何修复这些错误？
