I already have the remote cloned to a local directory, and am trying to switch to a particular branch.\n\nThanks!\n","author":{"url":"https://github.com/vasiliyb","@type":"Person","name":"vasiliyb"},"datePublished":"2015-04-01T14:19:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/523/nodegit/issues/523"}
