Pipenv lock hangs

Issue description

Run pipenv lock. Wait for an hour without visible progress

Expected result

Pipenv locks in reasonable time

Actual result

When possible, provide the verbose output (--verbose), especially for locking and dependencies resolving issues.

$ pipenv lock --verbose
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead.

Steps to replicate

Provide the steps to replicate (which usually at least includes the commands and the Pipfile). Run pipenv lock on following file:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
falcon = "*"
docker-compose = "*"
gunicorn = "*"
gensim = "*"

[dev-packages]
httpie = "*"

[requires]
python_version = "3.6"

Please run $ pipenv --support, and paste the results here. Don’t put backticks (`) around it! The output already contains Markdown formatting.

If you’re on macOS, run the following:

$ pipenv --support | pbcopy

If you’re on Windows, run the following:

It’s crazy it took almost 20 minutes to create the lock file and there was no sign of activity from the command line. At least you can provide a progress bar with an ETA to notify the user something is going on at background.

Please do not ever run pipenv with sudo, you will now need to sudo chown -R youruser:yourgroup ~/.cache/pipenv or wherever your cache directory is located. We really can’t provide support if you do this kind of thing

Do note that “hangs” is not a descriptive or actionable bug report. You will need to provide actual data, including runtime, network traffic, cpu usage of the process, etc, if you want us to act on your report. If you can’t or won’t provide that information, we can’t help you
