Package uploaded to anaconda but not installable

Developer Discussion

Hey there @cduvallet! I wonder if this error is related to the current path you are in when running the conda install command above --- if you are sitting in your q2-perc-norm repo, then there is a folder there called q2_perc_norm - is it possible conda thinks it should be looking in there to install the package from, instead of up towards the heavens (aka anaconda.org)?

On my dev machine I ran the following:

conda install -c cduvallet q2_perc_norm
Solving environment: done


==> WARNING: A newer version of conda exists. <==
  current version: 4.5.2
  latest version: 4.5.3

Please update conda by running

    $ conda update -n base conda

Getting help
To get help with QIIME 2, visit https://qiime2.org

One other thing that jumps out at me is that there is only a mac build of your plugin up on anaconda.org, that means if you are on a linux machine and try to install this package, conda will fail to resolve a valid linux-formatted package. Two ways around this come to mind:

  1. Build a version of your package on a linux machine (more work, need to have a linux computer)
  2. Build a noarch version of your package on your mac (less work).

The noarch package lets you upload one build that is compatible on multiple platforms - the caveat here is that it is up to you to know if that is the case or not (it looks like you should be safe to go with this option, I think :crossed_fingers:)

Good luck and keep us posted! :t_rex:
