任务：
将代码推送到存储库。
为了备份代码并跟踪您的工作，您需要提交您对项目存储库所做的更改。您必须打开终端并cd到正确的文件夹中，该文件夹包含此分配的克隆存储库。到那里之后，您将必须完成以下三个步骤：
1）暂存你的代码
git add -a
2）创建阶段代码的版本
git commit -m'创建了游戏逻辑'
3）将您的代码推送到GitHub存储库
git push origin master
我的最终结果：

error: unknown switch `a'

我甚至无法输入我的密码，我输入的内容没有任何打印输出，当我点击输入时，我收到上述错误消息。我已经阅读了这个问题的答案，但我无法解决它。请帮忙，谢谢。
作为@RohitShedage留下的解决方案的替代方案，您可以运行git add --all或git add -A。
请记住，git add .只适用于git已经跟踪的文件。
请尝试git add .而不是git add -a
试试git add -A，而不是git add -a
