I would like to have one YAML file that could serve to both create virtual environments and (most importantly) as a base for installing packages by conda into the global env. I am trying:
conda install --file ENV.yaml
But it is not working since conda expects
pip-like format of the requirements. What command should I execute to install packages from my YAML file globally?
You want the
conda-env command instead, specifically
conda env update -n my_env --file ENV.yaml
conda env update --help for details.
If you wish to install this in the base env, then you would use
conda env update -n base --file ENV.yaml
Note that the base env isn’t technically “global”, but rather just the default env as well as where the
conda Python package lives. All envs are isolated unless you are either using the
--stack flag during activation to override the isolation or have – contra recommended practice – manually manipulated
PATH to include an env.
If your conda env is already activated, use:
conda env update --file environment.yml
Or update a specific environment without activating it:
conda env update --name envname --file environment.yml
