无法解析字符串API数据

Question

我正在尝试访问从GitHub API返回的tags_url，但是由于typeof = string，我需要解析它才能访问它。我正在控制台中对此进行测试，并收到以下错误消息，但我不明白为什么。

//Returned data:
https://api.github.com/repos/open-guides/og-aws/tags
main.js:33 https://api.github.com/repos/aws/amazon-ecs-agent/tags
main.js:33 https://api.github.com/repos/mitchellh/goamz/tags
main.js:33 https://api.github.com/repos/aws/aws-cli/tags

main.js:33 https://api.github.com/repos/goamz/goamz/tags
main.js:33 https://api.github.com/repos/voldemort/voldemort/tags

console.log(JSON.parse(dataArr[0].tags_url));
