你需要在推送时指定哪个分支和哪个远程:

➤ git init ./
➤ git add Readme.md
➤ git commit -m "Initial Commit"
➤ git remote add github <project url>
➤ git push github master

将按预期工作。

默认情况下，你可以这样做:

➤ git branch -u github/master master

这将允许您在不指定远程或分支的情况下从master执行git推送。

在总结;

git init
git status
git add "*"
git commit -m "Comment you want"
git remote add origin  https://link
git push  -u origin master

我想与您分享一个源代码，以便您更容易地了解Git。

如果您想摆脱命令行，另一个选择是使用SourceTree。

这里有一些关于如何设置的额外资源:

连接到Bitbucket或Github 克隆远程存储库 创建本地存储库 添加现有的本地存储库

创建一个新的存储库

git clone <url>
cd "repositoryName"
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master

现有的文件夹

cd existing_folder
git init
git remote add origin <url>
git add .
git commit -m "Initial commit"
git push -u origin master

现有Git存储库

cd existing_repo
git remote rename origin old-origin
git remote add origin <url>
git push -u origin --all
git push -u origin --tags

git init
git add .
git commit -m "Initial commit"
git remote add origin <project url>
git push -f origin master

git push上的-f选项强制执行推送。如果你不使用它，你会看到这样的错误:

To git@github.com:roseperrone/project.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'git@github.com:roseperrone/project.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 merge the remote changes (e.g.,
hint: 'git pull') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Git自2005年问世以来一直是版本控制系统的首选。大约87%的开发者使用Git作为他们的版本控制系统。

但是如果你有一个已经存在的项目，并且你想要推送到远程服务器中的Git，请按照以下步骤执行:

Go to the terminal of your project directory You need to initialize your project git using git init Create a .gitignore file and it is actually a text file that tells Git which files or folders to ignore in a project. Stage your files using git add . Commit your changes to your local repository with an appropriate commit message: git commit -m "my first commit" In this step, you just need to create a repository in any one of the distributed version control systems like GitHub or Bitbucket Use this Git command to link your local repository with that of the remote: git remote add <your-remote-name> <your-remote-url>

所以，如果你的GitHub repo-url是https://github.com/your-github-username/new-repository.git，那么Git命令就变成:

git remote add origin https://github.com/<your-github-username>/new-repository.git

将代码推送到远程GitHub存储库 Git push origin master

注意:git push命令需要两个参数:远程存储库的名称(origin)和要推送的分支(这里master是每个存储库的默认分支)。
