使用Git bash遇到的一些问题解决方法
1.warning: LF will be replaced by CRLF in package.json.（原因是存在符号转义问题）
The file will have its original line endings in your working directory.
解决：git config --global core.autocrlf true（当 core autocrlf为true时，还有一个需要慎重的地方，当你上传一个二进制文件，Git可能会将二进制文件误以为是文本文件，从而也会修改你的二进制文件，从而产生隐患）
2.On branch master
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
nothing to commit, working tree clean（其根本原因是版本分支的问题）
3.当 git push origin branch_name时遇到报错如下：
fatal:'origin' does not appear to be a git repository
fatal:Could not read from remote repository
原因：
本地分支和远程分支断开连接
解决方法：
cd 本地分支里
（1）、git branch
——*master 只显示master
然后查看是否从上游拉了
（2）、git remote –v
——若什么都没有，则和上游已断联系，拉不了代码也推不了代码
加关联
（3）、git remote add origin ssh://git@pandaliusir.github.io(地址)
然后
（4）、git fetch origin
——会显示下拉的branch情况
再次检查远程仓库，显示对应的clone地址
git remote –v
——origin git://github.com/schacon/ticgit.git (fetch)
origin git://github.com/schacon/ticgit.git (push)
然后再查分支
git branch –a
——* mater
4.master合并分支时提示“Already up-to-date”
(git pull origin master
From https://github.com/pandaliusir/pandaliusir.github.io
- branch master -> FETCH_HEAD
Already up to date.)
在使用Git把当前分支合并到master提示“Already up-to-date”，但当前分支和 master 分支代码不同步。假设当前分支是：dev，主分支是：master。
解决方法：
git checkout master；
git reset --hard dev;
git push --force origin master
5.在执行git pull origin master时出现：
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists
解决方案：
git remote add origin git@github:bx_reader/bx-reader-api.git
将关联远程仓库为origin,然后再输入：
git push -u origin master
就可以提交了
ssh-keygen -t rsa -C “your@email.com”（填写自己的邮箱地址）回车
接下来会出现:(一路回车就可以)
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
之后打开提示的目录
C:Usersliusi.ssh
记事本打开
id_rsa.pub，
复制里面内容
进入自己的账号https://github.com/settings/keys 点击 New sshKey,复制的内容粘贴到Key里,标题可以不写。
验证：$ ssh -T git@github.com回车
Hi XXXXX! You’ve successfully authenticated, but GitHub does not provide shell access.
成功
6.git将本地内容传送到远程仓库出现![rejected] master -> master (fetch first)错误
问题：使用git push -u 远程库名 master 命令将本地提交的内容传到git远程库时出现错误：
命令： git push -u origin master
出现错误：
To https://github.com/imjinghun/university.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/imjinghun/university.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
解决：git pull --rebase origin master
git push origin master
7.fatal: remote origin already exists.
问题：
git remote add origin https://github.com/lookabc123/lookabc123.github.io.gi
fatal: remote origin already exists.
只要两步：
1、先删除
$ git remote rm origin
2、再次执行
