无法推代码github上

Question

我尝试用下面的命令来我的代码推到github上：

git remote add https://github.com/user/sample_app.git 

git push origin master 

而且得到了以下错误：

error: failed to push some refs to 'https://github.com/user/sample_app.git' 
To prevent you from losing history, non-fast-forward updates were rejected 
Merge the remote changes before pushing again. See the 'non-fast forward' 
section of 'git push --help' for details. 

要查看错误是否是在远程I进入：

git pull 

，并得到了以下错误：

error: SSL certificate problem, verify that the CA cert is OK. Details: 
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing https://github.com/sub1010/sample_app.git/info/refs 
fatal: HTTP request failed 

为什么我无法将我的代码推送到github？

Answer 1

尝试添加SSH回购，而不是HTTP回购这样

git remote rm sample_app 
git remote add git@github.com/user/sample_app.git 

Answer 2

Github上有详细说明上设置信息库，并确保你可以用它连接。链接：Github Setup和Github Create A Repo
