thumb When I run the jekyll serve command in my local Jekyll environment I got the following warning:

GitHub Metadata: No GitHub API authentication could be found. Some fields may be missing or have incorrect data.

Here’s the solution to fix this warning:

Step 1. Create the GitHub personal access token with public_repo scope. You can find guide here.

Note: Remember to keep the token secret - you don’t want other people to use the API on your behalf!

Step 2. Open the ~/.bash_profile file (you can use your favorite text editor instead of nano if you’d like).

nano ~/.bash_profile

Note: This file may have different names and locations depending on your shell and OS. For example: .profile, .bashrc, .zshenv. In MacOS is a .bash_profile that loacated at user home directory (~/). You can search in Google for information about file in your OS in wich you can add a new environment variable.

Step 3. Then define new environment variable with variable name JEKYLL_GITHUB_TOKEN and GitHub access token as variable value (which is something like abc123def456). You can do this by add the following line to a new blank line:

export JEKYLL_GITHUB_TOKEN='abc123def456'

Note: Replace the abc123def456 with your token.

Step 4. Now reload the Terminal.

You can check the new environment variable with the following command line that should display your GitHub token.


In addition

For security reason you can also access GitHub token with the following command line while building or serving Jekyll website:

JEKYLL_GITHUB_TOKEN=abc123def456 bundle exec jekyll serve

Also you can set temporary environment variable with the following command line:

export JEKYLL_GITHUB_TOKEN=abc123def456

The export command run by itself and not contained within .bash_profile will only be a temporary setting and the environment variable will not persist unless you add it to the .bash_profile.
