MinPin is a command-line tool that automatically adds minimum version pins from the conda list and pip list output to the unpinned packages in conda YAML files, such as environment.yml or anaconda-project.yml.

• Parses conda list and pip list outputs to retrieve installed package versions.
• Updates YAML files by adding minimum version pins to unpinned packages (and skips already pinned packed).
• Handles both conda and pip dependencies.
• Preserves the original structure and comments of the YAML file.

pip install minpin

Activate your environment and then run:

minpin <path/to/environment.yml or anaconda-project.yml>

Input: original environment.yml
