Cannot get correct dependency information

Pipenv seems to use dependency information of the wrong version.

$ pipenv --version
pipenv, version 11.8.0

Pipfile (which is auto generated from my requirements.txt)

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true

[packages]

google-endpoints = "==2.4.5"
google-endpoints-api-management = "==1.3.0"


[dev-packages]



[requires]

python_version = "2.7"

When I run pipenv lock --verbose, it fails with the following message.

However according to pypi google-endpoints 2.4.5 requires google-endpoints-api-management more than 1.2.1, so I think google-endpoints-api-management 1.3.0 I configured, matches google-endpoints 2.4.5.

Moreover, google-endpoints 2.4.5 doesn’t require semver, but the version 3.0.0 (latest version) requires it. I suppose Pipenv uses information of google-endpoints 3.0.0.

@milkcocoa I think it is fixed in 11.8.0, but you’re likely hitting a cache problem that prevents Pipenv from doing the right thing. Try deleting the Pipenv caches (~/Library/Cached/pipenv if you’re on macOS, not sure about other platforms) and start over.

@uranusjr Thanks a lot, I’ve confirmed it works correctly after deleting caches 😃
