pipenv

• Different project needs different version of dependencies.
• You can use pipenv to define different configurations per project.
• After Renaming the project, you need to run pipenv install again. As the virtualenv location is tied to the current project directory. (https://github.com/kennethreitz/pipenv/issues/796)

virtualenv

• Different project needs different python versions or environments.
• In virtual env, different python versions can be maintained.

Node vs Python

• In nodejs, we have nvm to manage different node versions and npm to manage/install dependencies.
• Every project contains package.json while here project contains Pipfile.
