<h2>近日使用“git add”出现如下错误：</h2>
$ git add . warning: You ran 'git add' with neither '-A (--all)' or '--ignore-removal', whose behaviour will change in Git 2.0 with respect to paths you removed. Paths like 'inc/jquery2.1.1/jquery.min.js' that are removed from your working tree are ignored with this version of Git. * 'git add --ignore-removal <pathspec>', which is the current default, ignores paths you removed from your working tree. * 'git add --all <pathspec>' will let you also record the removals. Run 'git status' to check the paths you removed from your working tree.
使用“git status”查看状态：
$ git status On branch master Your branch is up-to-date with 'origin/master'. Changes to be committed: (use "git reset HEAD <file>..." to unstage) modified: app/js/app.js new file: app/tpl/admin.html new file: app/tpl/home.html new file: inc/jquery.2.1.1/jquery.min.js modified: index.html Changes not staged for commit: (use "git add/rm <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) deleted: inc/jquery2.1.1/jquery.min.js
解决方法很简单：$ git add -A #或 git add -all
warning: Your console font probably doesn't support Unicode. If you experience strange characters in the output, consider switching to a TrueType font such as Lucida Console!解决办法：
$ git config --global core.autocrlf truewarning: push.default is unset; its implicit value is changing in Git 2.0 from 'matching' to 'simple'. To squelch this message and maintain the current behavior after the default changes, use: git config --global push.default matching To squelch this message and adopt the new behavior now, use: git config --global push.default simple
错误信息：warning: LF will be replaced by CRLF in XXXXXXXXXXXXXX.
解决办法：$ git config --global core.autocrlf false
事实上这并不会影响你push的结果，最终push还会成功，因为这只是一个”warning“
设置core.autocrlf=false，windows也用LF换行
除了记事本，其他编辑器都可以正常编辑
如果设置core.autocrlf = false，那么很可能会出现CRLF和LF混合的情况，这样会导致一些问题，例如git diff 失去功能，会发现很多行代码并没有修改，然而被认为是修改过了。
首先core.autocrlf = true在windows上才是正确的选择，那么如何避免warning呢？还要有以下几个步骤：
添加.gitattributes
设置core.safecrlf = true
使用dos2unix、notepad++等工具来将LF转换成CRLF

你可以按照他说的那样运行：git config --global push.default matching 或者 git config --global push.default simple命令，以后再push就不会有警告了。
下面说一下push.default matching和push.default simple的区别：
push.default设置maching的意思是：git push 会把你本地所有分支push到名称相对应的远程主机上。这意味着可能你会在不经意间push一些你原本没打算push的分支。push.default设置成simple的意思是：git push仅仅把当前所在分支push到从当初git pull pull下来的那个对应分支上，另外，这个过程也会同时检查各个分支的名称是否相对应。
