An error occurred using pickle install --source

[JesusuAllen]

I caught this error when I installed open-telemetry using pickle; I can generate github tokens, but I don't know how to configure them.

php pickle.phar install --source https://github.com/open-telemetry/opentelemetry-php-instrumentation.git#1.0.0beta2
