在本地与远程新建仓库并关联后，初次push可能会遇到以下问题
$ git push -u origin masterTo /xxxx/xxx.git! [rejected] master -> master (fetch first)error: failed to push some refs to '/xxxx/gittest.git'hint: Updates were rejected because the remote contains work that you dohint: not have locally. This is usually caused by another repository pushinghint: to the same ref. You may want to first integrate the remote changeshint: (e.g., 'git pull ...') before pushing again.hint: See the 'Note about fast-forwards' in 'git push --help' for details.
原因是因为远程仓库有一些文件而本地没有，通常是在远程建立仓库时有一些初始化文件比如Readme License 等，并且直接pull会提示warning: no common commits，对于此类问题可以采用两种解决办法
1.git push -f 强制将本地文件推送至远程，这样会将远程仓库的已有的文件清掉
2. git pull origin master –allow-unrelated-histories 使用此命令告诉 git 允许不相关历史合并 这样就能把远程文件拉取回来。执行此命令后会有一个提示，要求说明为何要讲两个不相关的分支合并，输入信息后保存即可。
拉取完不同的文件之后再执行git push -u origin master命令即可push成功。
