Please don't use sudo for this. The notion "install" does not imply 
being root.

The whole point of --user is to install packages in your personal 
account without troubling with the system packages. Doing that as root 
only installs the packages for root, generally a useless thing as you 
shouldn't be running normal stuff as root.

Just do pip3 as yourself.

That is odd, though I've seen this kind of complaint from pip before for 
some packages.

Try this (as _yourself_, not as root):

  pip3 install --verbose --user 'aiorpcX<0.18,>=0.17.0'

For me, this just worked.

Also, the output includes the location where pip is installing stuff.  
You could always just clean that area out and retry.

Also, try the --ignore-installed option and/or the --force-reinstall, 
which may cause pip3 to ignore any partial/damaged install and just do 
it all from scratch.

This is a fine place to ask this question.
