pipenv fails to install package that can be installed manually in the virtual env

[xirkus]

Issue description

I'm trying to use pipenv install with a package that has an older tensorflow dependency which fails with the following error. At first, I thought this problem was with the lib that I want to use, but the issue happens even if I try to install the dependency directly for example: pipenv install tensorflow==1.15.5:

 % pipenv install tensorflow==1.15.5
Installing tensorflow==1.15.5...
Error:  An error occurred while installing tensorflow==1.15.0!
Error text: 
ERROR: Could not find a version that satisfies the requirement tensorflow==1.15.5 (from -r /var/folders/sc/ycc3tm5d1js7bhb5kfvgwd0m0000gn/T/pipenv-ob9rvotp-requirements/pipenv-xb874qkn-requirement.txt (line 1)) (from versions: none)
ERROR: No matching distribution found for tensorflow==1.15.5 (from -r /var/folders/sc/ycc3tm5d1js7bhb5kfvgwd0m0000gn/T/pipenv-ob9rvotp-requirements/pipenv-xb874qkn-requirement.txt (line 1))

Expected result

pipenv install should be have similarly to pip install when run inside the virtual env.

Actual result

See error above.

Steps to replicate

1. pipenv --python 3.7 in a test directory.
2. pipenv shell to enter your virtual environment.
3. pip install --upgrade pip to upgrade to the latest version of pip in the virtual environment. Exit the virtual env.
4. Run: pipenv install tensorflow==1.15.5. You should get a failure.
5. pipenv shell to enter your virtual environment.
6. pip install tensorflow==1.15.5 within the virtual environment. This will work.

Hi,

I have a similar issue with jupyter. I have a solution which i am actually happy with so far in #4777 . Maybe you want to have a look.

Best regards
Franz
