Always getting "Failed to download wheel for pip" on Windows

[sschuberth]

On Windows 10 with Python 2.7.12 (and running from Git Bash) I'm always getting

$ pipgrip --tree pipgrip
Traceback (most recent call last):

RuntimeError: Failed to download wheel for pipgrip

I also tried with other Python packages, same thing. Any hint how to resolve that issue?

Hi @sschuberth,

Thanks for reporting this. I need to include Mac and Windows (and different pip versions) in tests. Especially for Windows, I'm sure there will be many errors like this.

Most likely, the cause of this error lies in the fact that pip formats their output messages slightly differently depending on pip version, python version, OS version, and pipgrip relies on this output to get the filename of the wheel (as pip is a CLI tool and shouldn't be imported as Python library).

As I don't have a Windows VM at hand, you could help me speed up the process by adding the output of pipgrip -vvv pipgrip, and pip wheel pipgrip, from your specific environment.

[sschuberth]

Sure:

$ pipgrip -vvv pipgrip

$ pip wheel pipgrip
