git clone報錯：Permission denied (publickey). fatal: Could not read from remote repository...

原文：git clone報錯：Permission denied (publickey). fatal: Could not read from remote repository…

今天clone一份github代碼，報錯：

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

查了資料發現是因爲本機的publickey沒有添加到github（因爲剛剛重裝了系統），之前一直以爲訪問公開庫沒有添加公鑰的要求，這波才知道原來只要是clone github代碼就需要添加公鑰

祕鑰生成

ssh-keygen -t rsa -C "youremail"

密碼不用設置，直接回車即可。完成後在 ~/.ssh 目錄生成兩個文件：id_rsa和id_rsa.pub

添加祕鑰

在github上添加ssh密鑰，這要添加的是id_rsa.pub裏面的公鑰
在github官網，點擊頭像->Settings->SSH and GPG keys->New SSH key，添加公鑰即可

添加公鑰之後，就可以從github正常拉取代碼了
