创建Git

• I don’t handle protocol 'git@https'

报错位置:git push
因为刚开始关联的仓库地址有误，重新关联

$ git remote rm origin
$ git remote add origin https://github.com/JillZsy/Flutter-jsDemo.git

• fatal: refusing to merge unrelated histories

报错位置:git pull origin master
由于git remote add之后，本地仓库和远程仓库实际上还是两个独立的仓库。如果用clone则不会有这个问题。

$ git pull origin master –allow-unrelated-histories

• git push error
  由于没有先git pull就git push -u导致了本地文件与github上README.md冲突

$ git push -u origin master
To https://github.com/JillZsy/Flutter-jsDemo.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/JillZsy/Flutter-jsDemo.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.

//此时远程库中README.md文件没有了，导致下面pull不成功

$ git pull origin master

$ git pull origin master –allow-unrelated-histories

$ git push -u origin master

 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/JillZsy/Flutter-jsDemo.git'

//最后强制提交成功
$ git push -u origin master -f
