How to create new Conda and .yml environment with updated Conda

Question

Can't create new conda or.yml environments from ananconda. Updated conda using

conda update --all

Updated to satisfy requirements of package I want to use (PyDESeq2). Before update I could create conda environments but received an error when attempting to create.yml environment. Now I can't even create a new conda environment.

Downloaded Repository from PyDESeq2 using

git clone https://github.com/owkin/PyDESeq2.git

Then attempted to create new conda version (per PyDESeq2 instructions) using

conda create env -f environment.yml

Received the following error:

usage: conda-script.py create [-h] [--clone ENV] (-n ENVIRONMENT | -p PATH) [-c CHANNEL] [--use-local] [--override-channels] [--repodata-fn REPODATA_FNS] [--strict-channel-priority] [--no-channel-priority]

Answer 1

It seems to be a typo in PyDESeq2 README. This should work.

conda env create -f environment.yml
