Issue when installing dogpile.cache module

[xocasdashdash]

Issue description

I have a Pipfile.lock with this version of dogpile.cache:

"dogpile.cache": {
            "hashes": [
                "sha256:fca7deb7c276b879b01c15c5d39b3c05701dc43b263ec3fef1e52cb851cf88ab"
            ],
            "index": "pypi",
            "version": "==0.6.7"
        },

If I run install with pipenv version (2018.7.1) it works, but if I run it with the current version (2018.10.9) it fails with this error:

An error occurred while installing dogpile-cache==0.6.7 --hash=sha256:fca7deb7c276b879b01c15c5d39b3c05701dc43b263ec3fef1e52cb851cf88ab! Will try again.

Expected result

It should install the package

Actual result

It fails
