Possible qiime2 conda install bug on Mac OS X

Hi there,

I just ran into this error when running the default conda install commands of qiime2 on Mac 10.13.2:
NoPackagesFoundError: Packages missing in current osx-64 channels:
- intel-openmp 2018.0.0*
- libgfortran 3.0.1*
- mkl 2018.0.1*

I added “anaconda” as a channel at the top of qiime2-2017.12-py35-osx-conda.yml and this issue was resolved.

These were the commands I ran:
wget https://data.qiime2.org/distro/core/qiime2-2017.12-py35-osx-conda.yml
conda env create -n qiime2-2017.12 --file qiime2-2017.12-py35-osx-conda.yml



Hi @gmdouglas - what version of conda are you running?

Can you please provide the output for conda info? I have done a few fresh installs of QIIME 2 2017.12 on macOS today, on three different machines and didn’t see this issue, for what its worth. Thanks! :t_rex:

Hi @thermokarst, I’m running version 4.2.13. It turns out that my installation didn’t work afterall (the “qiime” binary is not found in my path after activating the environment… :confused:). I think there is likely something wrong with my conda installation. See the conda info output below.

Hi @gmdouglas, at the moment we are only able to test and ensure that our environment files work with the latest conda (one of the first steps listed in the official native installation guide is to update conda). Are you able to update this deployment? Needing to add the “anaconda” channel to make things work on your machine makes sense though — more recent versions of the conda tool have changed up the default/base channels a bit. Anyway, thanks for the details and the follow-up! Please keep us posted! :t_rex:

D’oh >.< … that was indeed the problem. I re-installed qiime2 and it’s working now. Thanks a lot for your help @thermokarst!
