Creating environments

# By name only
conda create -n myenv 
# By name and with packages
conda create -n myenv python=3.11 jinja2=3.1.4 wheel
# From file
conda env create -f environment.yml -n myenv

Activating/deactivating environments

Activate an environment:
{{lang-bash}}conda activate myenv

Deactivate an environment:
{{lang-bash}}conda deactivate

Switch to base environment (same as deactivating):
{{lang-bash}}conda activate

Listing environments

conda info --envs
conda info -e

List packages in an environment

conda list

Export environment details

conda env export --no-builds --from-history

--no-builds means build numbers are not included (this is best practice).
--from-history means only explicitly installed packages are listed.

Add > environment.yml to the end to export the results to a file called environment.yml (this will overwrite a file with the same name, if it exists).

Deleting an environment

conda remove -n myenv --all

Rename an existing environment

conda rename --name old_env new_env
conda rename --prefix path/to/old_env new_env

Create a specfile

conda list --explicit > specfile.txt

Install packages into current environment

conda activate myenv
conda install matplotlib

Install specific package version

conda install numpy=1.11
conda install numpy==1.11
conda install "numpy>1.11"
conda install "numpy=1.11.1|1.11.3"
conda install "numpy>=1.8,<2"

Specify an environment to install packages in

conda install --name myenv matplotlib

Install packages based on file

conda env update -n my_env --file environment.yaml

Install package from non-default channel

conda install conda-forge::numpy

Install package from URL

conda install <URL> 
conda install https://anaconda.org/conda-forge/numpy/2.3.1/download/linux-ppc64le/numpy-2.3.1-py313h1a7af6e_1.conda
