Error installing with pip

[pnave95]

Bug report

I am trying to install moldesign through pip, but I receive an error stating that nbmolviz 0.7.0 has requirement moldesign>=0.8rc1, which I believe is the development version? If so, it seems that maybe nbmolviz is prematurely assuming the next version of moldesign and in the process is breaking the version currently available through pip. Any help getting past this issue so that I can successfully set up moldesign 0.7.3 would be greatly appreciated. Thanks! (errors from pip included below)

Description

Steps to reproduce

pip2 install --user moldesign

Here is the portion of the output containing the error:

nbmolviz 0.7.0 has requirement moldesign>=0.8rc1, but you'll have moldesign 0.7.3 which is incompatible.

Environment

• Operating system: Ubuntu 16.04
• python --version output: 2.7.12
• pip show moldesign nbmolviz | grep -B1 Version output:
  Name: moldesign
  Version: 0.7.3
  --
  Name: nbmolviz
  Version: 0.7.0

@diegovalenzuelaiturra I'm sorry, but I don't follow what you are saying. Are you telling me something to try? Can you please be a little more clear?

Installing nbmolviz with pip after receiving this message doing
$ pip install nbmolviz
worked for me.
