Versions Supported in Bioconda

The Bioconda build system only supports some versions of common software dependencies. Here is an incomplete list of the dependencies that might be relevant to your conda environment.

Operating Systems

Bioconda only supports 64-bit Linux and Mac OS


Bioconda only supports python 2.7, 3.6, 3.7, 3.8 and 3.9.

(The exception to this is Bioconda packages which declare noarch: python and only depend on such packages - those packages can be installed in an environment with any version of python they say they can support. However many python packages in Bioconda depend on other Bioconda packages with architecture specific builds, such as pysam, and so do not meet this criteria.)

Unsupported versions

If there is a version of a dependency you wish to build against that Bioconda does not currently support, please reach out to the Bioconda Gitter for more information about if supporting that version is feasible, if work on that is already being done, and how you can help.
