①问题：在准备使用Git时被拦在了创建秘钥报错：Too many arguments这里！
Administrator@USER-20180802ED MINGW64 ~
$ ssh-keygen -t rsa-c "XXX@XXX.COM"
Too many arguments.
usage: ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa]
[-N new_passphrase] [-C comment] [-f output_keyfile]
ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]
ssh-keygen -i [-m key_format] [-f input_keyfile]
ssh-keygen -e [-m key_format] [-f input_keyfile]
ssh-keygen -y [-f input_keyfile]
②分析：查了资料还是创建时使用的命令(后面标注的红色下划线部门)输入有问题：$ ssh-keygen -t rsa-c “XXX@XXX.COM”
③解决：下面给出正确的命令(绿色部分)格式：$ ssh-keygen -t rsa -C "XXX XX @qq.com"注意命令中大小写和空格。问题得以解决后代码如下：
Administrator@USER-20180802ED MINGW64 ~
$ ssh-keygen -t rsa -C "XXX@XXX.COM"
Generating public/private rsa key pair.
