The value of the GITHUB_TOKEN environment variable is being used for authentication

Following the steps in https://learn.microsoft.com/en-us/training/modules/github-copilot-across-environments/4-git-hub-copilot-for-the-command-line

After installing gh, I tried to run gh copilot explain "sudo apt-get", but I receive the error Error: No valid GitHub CLI OAuth token detected

~ % gh copilot explain "sudo apt-get"

✗ Error: No valid GitHub CLI OAuth token detected

To get started with GitHub Copilot in the CLI, please run: gh auth login --web -h github.com to authenticate via web browser.

Then I run gh auth login --web -h github.com then I have another error.

~ % gh auth login --web -h github.com
The value of the GITHUB_TOKEN environment variable is being used for authentication.
To have GitHub CLI store credentials instead, first clear the value from the environment.

I have GITHUB_TOKEN set in .zshrc

.zshrc

export GITHUB_TOKEN=ghp_************************************

How do I run gh auth login --web -h github.com to authenticate via web browser?

Solution

Add this line alias gh="env -u GITHUB_TOKEN gh $1" in .zshrc

.zshrc

export GITHUB_TOKEN=ghp_************************************
alias gh="env -u GITHUB_TOKEN gh $1"` in ``.zshrc`
