This short summary is based on the Anaconda blog post here https://www.anaconda.com/moving-conda-environments/. The original blog post is a great high-level summary for the various methods in conda for reproducing environments.

• OS and platform specific (pulls from repos)

  # On source environment:
  conda list --explicit > spec-list.txt
  

  # New conda environment:
  conda create --name new_env_name --file spec-list.txt
  

• Different platforms and OS (pulls from repos, also includes pip installed packages)

  # On source environment:
  conda env export > env.yml
  

  # New conda environment:
  conda env create -f env.yml
  

• Platform and OS specific, no internet on target

  # On source environment:
  conda install -c conda-forge conda-pack
  conda pack -n env_name \
      -o out_name.tar.gz \
      -p /path/to/pack/
  

  # New conda environment:
  mkdir -p env_name
  tar -xzf out_name.tar.gz -C env_name
  source env_name/bin/activate
  conda-unpack
