conda env remove -n my_env_name
- Update conda
conda update conda
- Update all packages in the current environment

conda env export --from-history > environment.yml
- Create a new environment and install dependencies listed in YML file.
conda env create -f environment.yml
pipenv
does not have built-in package search; make sure you search for the packages at PyPI.
The environments are based on the folder you're on. There is no need to manually name them, and there is no environment activation to take care of per se.
- Install a package (this will modify
Pipfile
andPipfile.lock
)pipenv install some_package
pipenv install some_package=1.0
- Access the pipenv shell (necessary for enabling the virtualenv and for your script to find the installed packages).
pipenv shell
- Exit a pipenv shell.
deactivate
- Install all dependencies to the system, avoiding virtualenvs entirely (useful for deployment in containers)
