using pysed in xonsh?

[Dave]

I'm just learning both xonsh and Python. Can I use pysed in xonsh? I tried and got this error.

➤ xpip install pysed
Collecting pysed

Using legacy 'setup.py install' for pysed, since package 'wheel' is not installed.

➤ echo "This is my cat, whose name is Betty" | pysed -r "cat" "dog"
Traceback (most recent call last):

PermissionError: [Errno 13] Permission denied: '/usr/lib/python3.9/site-packages/pysed/__init__.py'

The permissions on that file are:

-rw-r----- 1 root root 0 Jul  3  2015 /usr/lib/python3.9/site-packages/pysed/__init__.py

It seems those are not the correct permissions, but it also seems like simply changing the permission for that one file is not the right approach. Suggestions?
