UNable to install plivoxml module

[Larz60+]

If it is not part of pypi.org, it cannot be installed with pip, and this module is not.
I think you are looking for plivo, which is part of pypi

first make sure the version of pip in your environment is for the version of python you want to install plivo in

pip -V
# also check
pip3 -V

Then from command line (using proper pip version):

sudo pip3 install plivo
