如題：git創(chuàng)建密匙時(shí)報(bào)錯(cuò)Too many arguments。

前幾天我遇見(jiàn)了一個(gè)問(wèn)題，git需要重新創(chuàng)建密匙，運(yùn)行命令ssh-keygen -t rsa -b 4096 -C " [email protected] "時(shí)報(bào)錯(cuò)。

  Too many arguments.
  usage: ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa | rsa1]

當(dāng)然我第一時(shí)間就去網(wǎng)上查了，網(wǎng)上有人有說(shuō)加引號(hào)包裝，我也是醉了，雖然是解決了問(wèn)題但根本沒(méi)有說(shuō)到點(diǎn)上。

問(wèn)題的解決方式和原因應(yīng)該是這樣的。

首先你會(huì)看到官方提示要你替換成你的電子郵件地址，但是如果你只是粘貼覆的話，你就錯(cuò)了

Github給的粘貼文本中有空格，如果你不小心很容易被坑到，解決方案就是：

1.你眼尖點(diǎn)動(dòng)動(dòng)手把里面的空格刪除

2.在你的郵箱地址外加一層引號(hào)，目的是隔絕空格影響~
