Error: Could not find some dependencies for metawrap-mg: nettle 3.3.*, boost 1.64.0.*, bcftools 1.6.*

Did you mean one of these?

    bcftools

You can search for this package on Binstar with

    binstar search -t conda bcftools 1.6.*

 (and similarly for the other packages)

You may need to install the Binstar command line client with

    conda install binstar
(/gpfs0/home/group/user/Scratch/new_conda_env)qmaster02: Scratch$ which conda
~/Scratch/new_conda_env/bin/conda
(/gpfs0/home/group/user/Scratch/new_conda_env)qmaster02: Scratch$ conda --version
conda 3.14.1

Question : How do I resolve this?

[ursky]

Looks like the dependency versions for nettle, boost, and bcftools are in the wrong nomenclature. For example, bcftools 1.6.* doesn't technically exist because the actual version is 1.6-0. Very annoying and confusing because metawrap does not actually require these dependency versions (and nettle isn't required at all). So I have no idea where these faulty dependencies are coming from. I cant replicate it on my system. Try to install again, but enforcing the version: conda install metawrap-mg=1.0.6

[ursky]

Actually, I see where this is coming from. When the conda builds a new recipe, it automatically adds a .* to any fixed dependency version. However, conda should be smart enough to not literally look for that last period, which makes me think that your conda is just outdated. Try updating to conda v4.5.11 (that's what I have now), and see if it works.

Upgrading to a more recent version of conda seemed to work. The easiest thing was to install the most recent version of anaconda. Thank you for the help.

[ursky]

Great! Happy it worked out. I'll keep the issue open for visibility.
