github - git uploads projects to remote repositories

Question

I just came into contact with git. I configured sublime text3 according to the steps on the Internet, and then went to git push origin master. An error was reported at this step, so I used the method provided by the blogger and executed git pull origin master first, but I got an error and could not read the remote warehouse. , please give me some advice.
1. The error is reported as shown in the figure

I checked some information, added the key for the Permission denied error, and then re-ran git pull origin master
As shown in the figure:

When running push
I still get an error here, I don’t quite understand it, please give me some advice

Answer 1

After searching for information, I finally uploaded it successfully
Solution:
Error about pull: refusing to merge...
Because they are two different projects, to merge two different projects, git needs to add a line of code , in git pull, so
git pull origin master --allow-unrelated-histories
and then push is ok
git push origin master

Answer 2

First you need to bind it to the remote warehouse

Remember to change it to your warehouse name.

git remote add origin git@github.com:youngxhui/Test.git

If it is the first time to submit to the remote warehouse

$ git push -u origin master

If it’s not your first time, just use it

git push 

You can push
