我知道，这是一个老问题，但我试图解释每一步，所以它可以帮助别人。这是我如何添加一个现有的源代码到git:

Create the repo on the git, so you'll have the ssh || https where you're gonna remote add you source code. In your terminal go to the path of your project. Run git init (here you initiate the project as a git one). Run git add * (here you add all the files and folders from you project). Run git commit -m "Initial Commit." (here you commit your files and folders added in step #4; keep in mention that you can't push your changes without committing them). Run git remote add origin https://your_username@bitbucket.org/your_username/project-name.git (here you add a remote project where your source it's gonna be pushed; replace my link with your ssh || https from the step #1). Run git push -u origin master (here you push your source into the git repository).

注意:这些都是将源代码推入主分支的简单步骤。

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。

如果你用的是Mac(这可能在PC上也一样)，这里有一个非常简单的方法来做到这一点。奇怪的是，我到处寻找这个简单的方法，但始终没有找到。

Do not do anything on Github (other than having an account, and not having used up all your available repos). Download GitHub for Mac and install. Go through the account setup, etc. Do NOT create any repositories for your existing project. "Add New Local Repository" in repositories. Select your existing folder. It'll ask if you want to do that, say yes. Once done, you'll see a list of all your files, etc. Commit them. Go to Repositories and Publish (this will create the new repo on GitHub for you, if you set up your account properly). Go to Repositories and Push (you'll either see the "nothing to push" thing, or it'll push your files/changes to the newly-auto-made repo). Wonder why you could not find this simple process anywhere else.

我知道不建议使用项目文件夹作为回购文件夹。我一直这样做，它总是有效的，它使它变得简单，而且我从来没有遇到过任何麻烦。

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.

截至2019年7月29日，Github向用户提供了在创建回购时完成这项任务的说明，并提供了几个选项:

在命令行上创建一个新的存储库

git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/user/repo.git
git push -u origin master

从命令行推送现有存储库

git remote add origin https://github.com/user/repo.git
git push -u origin master

从其他存储库导入代码

按导入按钮初始化进程。
