Additional Comments

[jameslamb]

Thanks for using LightGBM.

At first glance, this does not really look related to LightGBM. Try upgrading to a newer version of pip or using a newer operating system so a wheel will be installed.

If that isn't an option or doesn't work, please provide us with enough information to help you.

• operating system
• version of pip
• exact command you're running
