解决方案

看起来你的gemrc文件可能被破坏。您可以删除该文件（或者更好地移动它）并查看内容。它的格式应该是 key：value 每行，或者 key：后跟一些缩进行。

解决方案

Looks like your gemrc file could be broken. You could just delete that file (or better move it away) and have a look at the contents. It should be in the form key: value per line, or key: followed by some indented lines.
