作為Github的一個(gè)新手氮采，你可能會(huì)遇到跟我一樣的狀況殷绍，其中過(guò)程就不說(shuō)了，詳細(xì)可以看我還活著：學(xué)習(xí)廖雪峰的Git教程鹊漠，這里的話就說(shuō)說(shuō)配公私鑰連接github的問(wèn)題篡帕，實(shí)際上就下面兩步殖侵。

上面中間空出來(lái)的說(shuō)明第二步，這里是正確完成的镰烧。看到Hi ***************! You've successfully authenticated就說(shuō)明正確連接楞陷，在github上也看得到公鑰被使用過(guò)的記錄怔鳖。
這里我必須解釋一下我犯的錯(cuò)誤,就是第二步直接按回車，然后去找其他方法固蛾。實(shí)際上回車的默認(rèn)選項(xiàng)是NO结执，而我們是要繼續(xù)連接才行，原理為什么第一次硬是找不到我也不清楚艾凯。
幾個(gè)我糾結(jié)的問(wèn)題說(shuō)一下：
- /c/Users/這種目錄路語(yǔ)法有沒(méi)有問(wèn)題献幔。這種一般我在linux看到，但是windows上是用C:\Users這樣的寫法的趾诗，你可以發(fā)現(xiàn)無(wú)法cd /c/Users蜡感，我一開(kāi)始以為是這個(gè)問(wèn)題，后面驗(yàn)證了發(fā)現(xiàn)是有這樣的語(yǔ)法的恃泪，只是可能windows的cd不支持郑兴，你用ls /c/Users是找得到的。
- 因?yàn)槟J(rèn)是驗(yàn)證~/.ssh/id_rsa贝乎，如果你確實(shí)覺(jué)得目錄語(yǔ)法有問(wèn)題情连，實(shí)際上你可以在ssh后加上-i選項(xiàng)來(lái)指定你的文件，如ssh -vT git@github.com -i D:\id_rsa览效，然后你會(huì)發(fā)現(xiàn)debug出來(lái)的目錄格式就是你的格式
- -v是debug選項(xiàng)却舀，當(dāng)然你可以不加，但是作為程序員锤灿，你有責(zé)任和義務(wù)知道它到底做了什么挽拔，特別是出錯(cuò)的時(shí)候
總結(jié)：
嘗試在是否嘗試連接后加個(gè)yes而不是直接回車，回車默認(rèn)不一定就是yes衡招，B了狗了篱昔，默認(rèn)是NO又不說(shuō)一聲！
