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

[lentil824]

Hi, I am having issues with the installation of this package using "conda install -c bioconda surpyvor" The error message is: UnsatisfiableError: The following specifications were found to be incompatible with each other: Output in format: Requested package -> Available versions I used conda installed pbsv, and svim (created new environment for svim as recommended) , no issues at all. I also tried to install surpyvor by creating a new environment "conda create -n surpyvor_env --channel bioconda surpyvor", the same error message again. Could you help on this?

Thanks, Susan

Hi, I also put the bcftools (version 1.12), htslib (version 1.12), SURVIVOR into the PATH, installed all required modules for python 3.7 (python version I have: numpy 1.18, cyvcf2 0.30.4, matplotlib 3.2.1, matplotlib-venn 0.11.6, upsetplot 0.4.1) . Still the same error message. The detailed log showed below after conda install:

Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Looking for incompatible packages. failed UnsatisfiableError: The following specifications were found to be incompatible with each other: Output in format: Requested package -> Available versions

I need some help to know which package caused the conflict. Thanks, Susan

Could you please try again with mamba? Mamba is a drop-in replacement for conda, usually faster and better at resolving these conflicts.

You can install mamba with conda itself: conda install mamba and from then on you can use mamba instead of conda, e.g. mamba create -n surpyvor_env --channel bioconda surpyvor.

Also make sure you have configured the channels appropriately for bioconda (see the documentation).

Thank you for the suggestion! I added the channel conda-forge, installed Mamba through conda-forge, then used mamba to install surpyvor. It is good now. Thank you!

Hi, I am encountering a similar issue with both conda and mamba. Mamba gives the following:
