fixed issue with current obspy install via conda-forge channel

[derick-hess]

I ran into this issue on pretty much every machine I tried obspy/obspy#1677

In order to ensure the correct version of modules are installed while obspy fixes this I added the needed versions into our yml to make sure everything works correctly.

Eh travis was complaining about not being able to find icu 58* so i just put the instructions in the readme and wiki install instructions for now

Yeah I noticed you added a set to the install instructions in the WIki stating:

run conda install 'matplotlib<2' 'icu=56.*' 'libxslt=1.1.29=2'

Shouldn't these just be defined in the environment.yml file?

[derick-hess]

for some reason travis always says icu is not found in the linux packages and fails even though you can install them with conda install. I might not have been putting it in correctly though.

I added them to the environment.yml file and it seems to have worked locally. I'll push this to a branch now to see if it works with travis-ci.

dependencies:

• six
• Cython
• nose
• numpy
• numexpr
• pyproj
• PySide
• psutil
  - matplotlib<2
• basemap
• obspy
• vispy
  - icu=56.*
  - libxslt=1.1.29=2
• pip:
  • construct==2.5.1
  • simplekml
  • tables

[derick-hess]

yeah it worked locally for me as well but failed in travis. I think icu was the only issue

[nick-falco]

I'll work on fixing this. There should be a way to get it working in Travis-CI.
