The first question: how can I pull my local warehouse code to the GitHub site?

Git push Origin master

warning:permanently added ' github.com,192.30.255.112 ' (RSA) to the list of known hosts.
To Github.com:lanshanxiao/yunweather.git
! [Rejected] Master--master (fetch first)
Error:failed to push some refs to ' [email protected]:lanshanxiao/yunweather.git '
Hint:updates were rejected because the remote contains work the
Hint:not has locally. This was usually caused by another repository pushing
Hint:to the same ref. Want to first integrate the remote changes
Hint: (e.g., ' git pull ... ') before pushing again.
Hint:see the ' Note about Fast-forwards ' "Git push--help ' for details.

The above executed three times, but all error, although pull down the remote repository code, but no

Git pull Origin master//merges local warehouse code and remote repository code

If you have the following error:

fatal:refusing to merge unrelated histories//description Local repository cannot be fused with remote warehouse code

To force the fusion to be allowed:

Git pull Origin master--allow-unrelated-histories

The second question: even though the SSH password has been added to GitHub, Permission denied (PublicKey) will still appear? You may not have the public key added to this machine

warning:permanently added ' github.com,192.30.255.112 ' (RSA) to the list of known hosts.
Permission denied (PublicKey).
Fatal:could not read from remote repository.

First, follow the steps on Baidu, the SSH password (C:\Users\ user name \.ssh\id_rsa.pub) in the password added to their own GitHub website, this can be Baidu.

Running GIT push Origin master again has the error above, and then the point is:

ssh-agent.exe//Running Agent

SSH-VT [email protected]

ssh-add-l//Small Letter L

Ssh-add

ssh-add-l//Small Letter L

The above command is to run SSH on the local computer and add the public key in.

Git ls-files//to view the files that have been submitted.
