尝试使用普通的Windows shell，如CMD。

这里什么都试过了，都没用。

然而，当我试图通过gitconfig——system——list进行调试时，我得到了致命的结果:无法读取配置文件'/etc/gitconfig':没有这样的文件或目录。

所以我做了以下的事情，

sudo ln -s $HOME/.gitconfig /etc/gitconfig

瞧，它起作用了。

TL;DR:检查是否可以读写/dev/ ty.如果没有，并且已经使用su打开shell，请检查是否使用正确。

我也遇到了同样的问题，但在Linux上，我发现了这个问题。我没有存储我的证书，所以我总是在提示时输入它们:

Username for 'https://github.com': foo
Password for 'https://foo@github.com': 

git处理http(s)连接的方式是使用/usr/lib/git-core/git-remote-https 你可以在这里看到strace:

所以我试着直接调用它:

echo "list for-push" | strace /usr/lib/git-core/git-remote-https my

结果是:

poll([{fd=3, events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}], 1, 0) = 1 ([{fd=3, revents=POLLIN|POLLRDNORM}])

) = 83
exit_group(128)                         = ?
+++ exited with 128 +++

我突然想到:

openat(AT_FDCWD, "/dev/tty", O_RDONLY)  = -1 ENXIO (No such device or address)
...
write(2, "fatal: could not read Username f"..., 83fatal: could not read Username for 'https://github.com': No such device or address
) = 83

git-remote-https尝试通过/dev/tty读取凭据，所以我测试了它是否有效:

$ echo ahoj > /dev/tty
bash: /dev/tty: No such device or address

但在另一个终端:

# echo ahoj > /dev/tty
ahoj

我知道我用su切换到这个用户，所以我退出了shell，看看如何，发现我使用命令su danman -所以我再次测试了它:

~# su danman -
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
/root$ echo ahoj > /dev/tty
bash: /dev/tty: No such device or address

我可能忽略了这条信息，继续工作，但这就是原因。 当我切换使用正确的su - danman一切工作正常:

~# su - danman
danman@speedy:~$ echo ahoj > /dev/tty
ahoj

在此之后，git开始正常工作

这是系统凭据缓存中存储的凭据的问题。你可能有配置变量“credential”。Helper '设置为wincred或winstore，它无法清除它。如果启动控制面板并启动凭据管理器applet，那么在标记为git:https://github.com的通用凭据部分中寻找项目。如果您删除了这些，那么下次将重新创建，但是凭据帮助实用程序将要求您提供新的凭据。

索尔:- 如果存储库是私有的，它也属于另一个人或组织，并且你是该存储库的贡献者，那么你可以从Jenkins作业中运行git命令，它不会提示你输入用户名和密码。

https://username:token@github.com/accountname/reponame.git

当试图克隆无效的HTTP URL时，也会发生此错误。例如，这是我在试图克隆一个GitHub URL时得到的错误，这是几个字符:

$ git clone -v http://github.com/username/repo-name.git
Cloning into 'repo-name'...
Username for 'https://github.com': 
Password for 'https://github.com': 
remote: Repository not found.
fatal: Authentication failed for 'https://github.com/username/repo-name.git/'

但是，它实际上发生在Emacs内部，所以Emacs中的错误看起来是这样的:

fatal: could not read Username for ’https://github.com’: No such device or address

因此，它没有给出一个有用的错误，告诉我那个URL上没有这样的回购，而是给了我这个错误，让我徒劳地追逐，直到我最终意识到URL是错误的。

这是git 2.7.4版本。

我在这里张贴这个，因为一个月前发生在我身上的事情，刚刚又发生了一次，让我再次陷入同样的徒劳。>:(
