my environment

Ubuntu 20.04.4 LTS
ROS:noetic 1.15.14
libboost-filesystem-dev  1.71.0.0
libboost-system-dev 1.71.0.0
libboost-thread-dev 1.71.0.0

libboost-iostreams-dev 1.71.0.0
libboost-python-dev 1.71.0.0

libode-dev 2:0.16-3build1

I followed Install OpenRAVE to install OpenRAVE.
However, /usr/local/lib/python2.7/dist-packages/openravepy/ not found
I checked the folders and the following folders exist,

/usr/local/include/openrave-0.98
/usr/local/share/openrave-0.98
/usr/local/lib/openrave0.98-plugins

so only openravepy is not installed.I also checked with pip list and there was no openravepy.
It is possible to view "openrave data/lab1.env.xml" and I can also view the .dae file.
But I can't use the openrave python package
I did not get any errors when I installed it using the method in the URL above.
If you know how to install openravepy with ros noetic, please tell me how to do it.
