Git创建秘钥时提示：too many arguments解决

创建创建秘钥时，出现如下错误

Too many arguments.

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 “[email protected]”

解决：

下面给出正确的命令(红色部分)格式：

 <font color = 'green'>  `ssh-keygen -t rsa -C` </font>"  [email protected]"

注： 注意命令中大小写和空格， myeail换为自己的邮箱

问题得以解决后代码如下：

Administrator@USER-20180802ED MINGW64 ~
$ ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):

在三个黄色箭头位置时： 按回车； 第一个红色方框为创建SSH Key的命令， 第二个红色方框为密匙存储的位置

验证代码：

cd ~/.ssh

注：必须创建SSH Key后才能使用此命令

创建完成后，在用户主目录里找到.ssh目录，里面有id_rsa和id_rsa.pub两个文件，这两个就是SSH Key的秘钥对，id_rsa是私钥，不能泄露出去，id_rsa.pub是公钥，可以放心地告诉任何人
