CondaValueError: Malformed version string '~': invalid character(s)

Tags:

I'm getting a Malformed version string error with my conda. I have no idea how to debug this or how to check it.

Can anyone help? GitHub has talked about the issue but I haven't seen any fixes.

-bash-4.1$ conda install -c bioconda pysam
Solving environment: failed



 1. CondaValueError: Malformed version string '~': invalid character(s).

This looks like it was fixed with Conda 4.6.0. Upgrading your Conda should resolve the issue.

conda upgrade -n base conda

If you have trouble solving environment, I suggest trying

conda upgrade -n base -c defaults --override-channels conda

This will exclude all other channels during the solving process, and helps because having too many options to prune is one of the main reasons for slow solves.
