<![CDATA[py编译报错]]>虚拟机 Ubuntu22.04 使用一键安装 ROS2，机器安装的 python3.10，setup.py 文件 使用 setup() 时报错

  File "/home/nli/.local/lib/python3.10/site-packages/sphinx/util/typing.py", line 34, in <module>
    from types import Union as types_Union
ImportError: cannot import name 'Union' from 'types' (/usr/lib/python3.10/types.py)

发现是安装后上面报错定位的代码有逻辑问题，修改为如下可以正常编译

if sys.version_info > (3, 10):
    from typing import Union as types_Union
else:
    from types import Union as types_Union
    # types_Union = None
