pipenv lock -r

Install a package in the currently active environment

pipenv install camelcase

Uninstall a package in the currently active environment

Install dev packages/dependencies (only meant for your dev environment, not for production)

pipenv install nose --dev

Install from a requirements.txt file (code assumes the text file is located at project folder/requirements.txt)

pipenv install -r ./requirements.txt

Check for security vulnerabilities
If the check suggests to update versions for a package, simply change the versions in pipfile.
Then, run pipenv install to update the package to the latest version.
Run pipenv check to confirm there are no additional security vulnerabilities.

pipenv check

View a dependency tree/graph of the environment

Prepare the pipfile.lock for installing same dependencies on production environment

pipenv lock

Install on production environment using pipfile.lock but ignore pipfile

pipenv install --ignore-pipfile

Run pipenv’s python without activating the pipenv environment
– run a command inside the virtualenv with pipenv run

pipenv run python
