Why is "pipenv install" not installing any packages?

Question

pip freeze shows all the packages, but when I pipenv install it is not installing any packages.

Here's what I'm getting when I do pipenv install:

Installing dependencies from Pipfile.lock (0a15b8)...

Answer 1

I solved this with:

pipenv update
pipenv install

Answer 2

I expect you are using pipenv virtual env as well for your project. I uninstalled all the packages from the env using: pipenv uninstall --all and then did pipenv install to install all the packages from pipfile and it worked.
