bundle exec jekyll server运行时发生以下错误

GitHub Metadata: No GitHub API authentication could be found. Some fields may be missing or have incorrect data
无法获得GitHub API认证，应该怎么做
很喜欢这个demo啊，望大佬指点，早日应用于博客上

Start by reproducing the reported `bundle exec jekyll server` error and reading the GitHub Metadata authentication warning. Confirm what authentication setup is required for the demo and document or verify a working resolution; the issue is done when the server runs without the reported warning or the limitation is clearly explained.
