Install declarativewidgets without "pip install"

[lcjr86]

Hello everyone,

I would like to know if is possible to install the declarative widgets without using:
pip install jupyter_declarativewidgets

I tried running python setup.py build and python setup.py install and after jupyter declarativewidgets quick-setup --sys-prefix and the message that I have is:

ImportError: No module named 'declarativewidgets'

There is another way to do that?

Thank you in advance.
