I am trying to install a github project using composer and get the following error
Composer [UnexpectedValueException] Your Github oauth token for github.com conta
I fixed it.
Goto C:\Users\XXXXX\AppData\Roaming\Composer
Open the auth.json
delete the github.com entry under "github-oauth": {}
That's it.
As far as I know (I'm a beginner with composer too), the problem is with your authentication, so you have to fix your credentials in auth.json inside path-to-composer/.composer/
Inside you will find a json which will probably looks like:
{
"github-oauth": {
"github.com": null
}
}
Fix that and you should be ok ;)
