`1. 部署中的问题`

[ 报错 ]

$ git push -u origin master
error: src refspec master does not match any
error: failed to push some refs to '116.62.138.9:linux0224/my_halo.git'

[ 原因 ]

受到"Black Lives Matter"运动的影响，GitHub 从今年 10 月 1 日起，在该平台上创建的所有新的源代码仓库将默认被命名为 “main”，而不是原先的"master"。

[ 解决 ]

推送现有的 Git 仓库
$ cd halo
$ git remote rename origin 
$ git remote add origin git@116.62.138.9:linux0224/my_halo.git
$ git push --set-upstream origin --all

[ 原因 ]

  文件夹内少了一个known_hosts文件，本来密钥文件应该是三个，现在只有两个，便报了这样的错误，此时输入yes回车之后，生成了缺少了的known_hosts文件，便可解决这个问题

`2. 代码push的问题`

[ 报错 ]

qs@DESKTOP-2LPH6D7 MINGW64 ~/Desktop/halo (main)
$ git add test.sh
warning: in the working copy of 'test.sh', LF will be replaced by CRLF the next time Git touches it

[ 原因 ]

	格式化与多余的空白字符，特别是在跨平台情况下，有时候是一个令人发指的问题。由于编辑器的不同或者文件行尾的换行符在 Windows 下被替换了，一些细微的空格变化会不经意地混入提交，造成麻烦。虽然这是小问题，但它会极大地扰乱跨平台协作。
其实，这是因为在文本处理中，CR（CarriageReturn），LF（LineFeed），CR/LF是不同操作系统上使用的换行符
---

通俗解释
	git 的 Windows 客户端基本都会默认设置 core.autocrlf=true，设置core.autocrlf=true, 只要保持工作区都是纯 CRLF 文件，编辑器用 CRLF 换行，就不会出现警告了；
Linux 最好不要设置 core.autocrlf，因为这个配置算是为 Windows 平台定制；
Windows 上设置 core.autocrlf=false，仓库里也没有配置 .gitattributes，很容易引入 CRLF 或者混合换行符（Mixed Line Endings，一个文件里既有 LF 又有CRLF）到版本库，这样就可能产生各种奇怪的问题。

[ 解决 ]

情况一：
    Git 可以在你提交时自动地把回车（CR）和换行（LF）转换成换行（LF），而在检出代码时把换行（LF）转换成回车（CR）和换行（LF）。 你可以用 git config --global core.autocrlf true 来打开此项功能。 如果是在 Windows 系统上，把它设置成 true，这样在检出代码时，换行会被转换成回车和换行：

#提交时转换为LF，检出时转换为CRLF
$ git config --global core.autocrlf true


情况二：
    如果使用以换行（LF）作为行结束符的 Linux 或 Mac，你不需要 Git 在检出文件时进行自动的转换。然而当一个以回车（CR）和换行（LF）作为行结束符的文件不小心被引入时，你肯定想让 Git 修正。 所以，你可以把 core.autocrlf 设置成 input 来告诉 Git 在提交时把回车和换行转换成换行，检出时不转换：（这样在 Windows 上的检出文件中会保留回车和换行，而在 Mac 和 Linux 上，以及版本库中会保留换行。）

#提交时转换为LF，检出时不转换
$ git config --global core.autocrlf input


情况三：
    如果你是 Windows 程序员，且正在开发仅运行在 Windows 上的项目，可以设置 false 取消此功能，把回车保留在版本库中：

#提交检出均不转换
$ git config --global core.autocrlf false
	#你也可以在文件提交时进行safecrlf检查

#拒绝提交包含混合换行符的文件
git config --global core.safecrlf true   
 
#允许提交包含混合换行符的文件
git config --global core.safecrlf false   
 
#提交包含混合换行符的文件时给出警告
git config --global core.safecrlf warn
