Managing dependencies

[veleritas]

How are we supposed to install the hetio package which is part of the repo's dependencies? The environment.yml file has a hard coded path (/home/dhimmels/Documents/github/hetio)==0.1.0.

I tried downloading version 0.1.0 of the hetio package from https://github.com/dhimmel/hetio/releases and changing the hard coded path to the local path instead, but received the following error when trying to run conda env create -f environment.yml:

Extracting packages ...
[      COMPLETE      ]|###################################################| 100%
Linking packages ...
[      COMPLETE      ]|###################################################| 100%
Invalid requirement: 'hetio (/home/ubuntu/hetio)==0.1.0'
It looks like a path. Does it exist ?
CondaValueError: Value error: pip returned an error.

Any ideas? I have also tried to install from the github directly instead of using a local path, but I get a dependency error with pypandoc instead (i.e. in environment.yml have the following line: - "--editable=git+https://github.com/dhimmel/hetio.git#egg=hetio") see this issue.

Okay can you now try:

conda env create --file environment.yml

One issue is that the environment is not cross-platform compatible (related comment on issue). It works on Linux, but currently not on Mac, which produces the following error message:

Error: Packages missing in current osx-64 channels: 
  - fontconfig 2.11.1 5
  - libgfortran 3.0 0
  - numpy 1.10.4 py35_1
  - scipy 0.17.0 np110py35_2

It's not impossible to fix this (we could just more loosely specify those package versions).

@veleritas are you on linux?

Yes, I'm on Ubuntu 16.04. Works without any problems now, thanks!
