如题：git创建密匙时报错Too many arguments。
前几天我遇见了一个问题，git需要重新创建密匙，运行命令ssh-keygen -t rsa -b 4096 -C " your_email@ample.com "时报错。
Too many arguments.

当然我第一时间就去网上查了，网上有人有说加引号包装，我也是醉了，虽然是解决了问题但根本没有说到点上。
问题的解决方式和原因应该是这样的。
首先你会看到官方提示要你替换成你的电子邮件地址，但是如果你只是粘贴覆的话，你就错了
Github给的粘贴文本中有空格，如果你不小心很容易被坑到，解决方案就是：
1.你眼尖点动动手把里面的空格删除
2.在你的邮箱地址外加一层引号，目的是隔绝空格影响~
