error installing picrust2 plugin

Hi there,

I am trying to install the Picrust2 plugin and am getting the following error.
(qiime2-2019.4) MacBookPro-A820662210AA-4:qiime2 alisonwaller$ conda install q2-picrust2=2019.4 -c conda-forge -c bioconda -c gavinmdouglas

Collecting package metadata (current_repodata.json): done

UnsatisfiableError: The following specifications were found to be incompatible with each other:

  • conda-forge/osx-64::gsl==2.2.1=blas_openblashddceaf2_6 -> *[track_features=blas_openblas]

Any suggestions would be helpful.

I tried updating openblas, but that didn’t change anything.

thanks

Hey @awaller,

Looks like conda fell into its standard “blas dance”. These are always tricky to resolve. You might be able to try this:

conda uninstall blas --force

which should have no practical effect as blas isn’t actually real, but a marker for different linear algebra implementations. Then try installing picrust2 again.

Be prepared for the above to fail miserably as I haven’t tested it (I use Linux). In that event, destroy the environment/reinstall and we can try other things (thankfully conda makes that easy at least).
