推荐答案
在您的终端窗口中，转到编辑">配置文件首选项">标题和命令"，然后选中将命令作为登录外壳运行"框.重新启动您的终端并立即尝试 ruby -v 和 gem -v.版本应该出现.如果没有，请尝试重新安装它们.
On your Terminal window go to Edit>Profile Preferences>Title and command, and check the box that says "Run command as a login shell". Restart your Terminal and try ruby -v and gem -v now. The versions should come up. If they don't then try re-installing them.
