在 GitLab 中创建 README.md

Question

我在 GitLab（在浏览器中）创建了一个新的空白项目。我选中了“使用 README 初始化存储库”框。但是打开它时，它说：“这个项目的存储库是空的。”我假设我仍然需要初始化一个 README.md 文件以便主分支存在？所以在我尝试的命令行中（我使用的是Windows 10）：

git clone https://gitlab.com/url/myproject.git
cd myproject
git switch -c main
touch README.md
git add README.md
git commit -m "add README"

但它说：

C:\Users\me>git clone https://gitlab.com/ur/myproject.git
fatal: destination path 'myproject' already exists and is not an empty directory.

C:\Users\me>cd myproject

C:\Users\me\myproject>git switch -c main
fatal: A branch named 'main' already exists.

C:\Users\me\myproject>touch README.md
'touch' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\me\myproject>git add README.md

C:\Users\me\myproject>git commit -m "add README"

On branch main
Your branch is based on 'origin/main', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)

nothing to commit, working tree clean

我的项目仍然是空的，我无法添加或推送任何内容。为什么？

编辑：如果我导航到项目并执行dir，我会得到（我只删除了卷序列号）：

C:\Users\me\myproject>dir
 Volume in drive C has no label.
 Volume Serial Number is ...

 Directory of C:\Users\me\myproject

13.12.2021  09:29    <DIR>          .
13.12.2021  09:29    <DIR>          ..
13.12.2021  09:29                 0 README.md
               1 File(s)              0 bytes
               2 Dir(s)  112.515.997.696 bytes free

让我们一一分解错误。

C:\Users\me>git clone https://gitlab.com/ur/myproject.git
fatal: destination path 'myproject' already exists and is not an empty directory.

myproject 文件夹已经存在 - 很可能您已经克隆了项目，所以这里没有更多的事情要做。

C:\Users\me\myproject>git switch -c main
fatal: A branch named 'main' already exists.

您无法创建 main 分支，因为它已经存在 - 再说一遍，这里无事可做。

C:\Users\me\myproject>touch README.md
'touch' is not recognized as an internal or external command,
operable program or batch file.

touch 是 Windows 中不存在的 *nix 命令。一种选择是使用 Git Bash 而不是 CMD，它提供了一个 touch 可执行文件。或者，您可以使用another method to create an empty file in Windows。

C:\Users\me\myproject>git add README.md

C:\Users\me\myproject>git commit -m "add README"

On branch main
Your branch is based on 'origin/main', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)

nothing to commit, working tree clean

这两个命令没有失败，它们什么也没做，因为README.md 文件没有创建。创建完成后，您可以重复这两个命令，它们应该会成功。
