How can I recreate my conda environment using yml file?

Question

My conda export was done like this: conda env export --file environment.yml -n djangoenv

The file itself looks like this:

name: djangoenv

- bioconda
- anaconda-cluster
- defaults

Answer 1

conda env update --prefix ./env --file environment.yml --prune

ref: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#updating-an-environment

To update a specific environment if you aren't just using the default, add --name [env name] to the above command.
