Hi! I’m also having trouble installing metaphlan 4.
I created a new conda environment, activated it and ran conda install -c bioconda metaphlan but this installed metaphlan version 3. I then tried updating by specifying the version with conda install -c bioconda metaphlan=4.0.0 and conda install -c bioconda metaphlan=4.0.1 but received an error about python being incompatible. My version of python when creating the environment was 3.7.2, but after inadvertently installing metaphlan 3, it seemed to have been downgraded to 3.6.
So I removed the environment, created a fresh environment (python 3.7.2), activated it, and tried various versions of the install command: conda install -c bioconda metaphlan=4.0.0, conda install -c bioconda metaphlan=4.0.1, conda install -c bioconda -c conda-forge metaphlan=4.0.1. Each time I get a variation of the following error about incompatible packages, despite this being a brand new environment:
Collecting package metadata (repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: \
Found conflicts! Looking for incompatible packages.

The packages being “examined” aren’t always the same, but the error always progresses very slowly and doesn’t seem to finish in a reasonable time frame. I waited over an hour the first time, but eventually killed it.
I’ve tried changing the priority configuration of my conda channels, moving bioconda or conda-forge to the top, setting priority as strict or false, but nothing has helped.
Other conda packages and metaphlan3 have installed without issues, so I’m pretty stumped as to what is going on. If you have any suggestions, I’d really appreciate it!
Thanks!
