How to fix “Non-zero exit code (1)” when installing scikitlearn

Scikitlearn won't download due to a newer version of pip that needs to be downloaded first. My OS is Windows 10.

I've tried to run Windows Command Prompt as an administrator and used -m pip install --upgrade pip as well as pip easy_install.
