git 里面遇到的问题

---

第一步：建立git仓库（本地）
cd到你的本地项目根目录下，执行git命令

git init

第二步：将项目的所有文件添加到仓库中

git add .

如果想添加某个特定的文件，只需把.换成特定的文件名即可

第三步：将add的文件commit到仓库

git commit -m "注释语句"

第四步：去github上创建自己的Repository，创建页面如下图所示：

第五步：重点来了，将本地的仓库关联到github上

git remote add origin https://github.com/Interesting6/my_numeral_calculations.git

后面的https链接地址换成你自己的仓库url地址

第六步：上传github之前，要先pull一下，执行如下命令：

git pull origin master

敲回车后，会执行输出类似如下

第七步，也就是最后一步，上传代码到github远程仓库

git push -u origin master

执行完后，如果没有异常，等待执行完就上传成功了，中间可能会让你输入Username和Password，你只要输入github的账号和密码就行了

-----------------------------------------------------------------------------------------------------------------------------------

遇到的问题，有时我只需要上传一个文件，而这个文件在GitHub上还没有目录，在刚刚仓库（本地）的目录下打开git bash：

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git add ./functionroot/iteration_method.py 
# 添加该functionroot目录下的文件iteration_method.py 

然后提交一下

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git commit -m "solving nonlinear function in iteration method"
[master c08aed3] solving nonlinear function in iteration method
 1 file changed, 133 insertions(+)
 create mode 100644 functionroot/iteration_method.py

然后push就出错了：

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git push -u origin master
To https://github.com/Interesting6/my_numeral_calculations.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/Interesting6/my_numeral_calculations.git'
hint: Updates were rejected because the remote contains work that you do         # 更新被拒绝，因为远程包含本地没有的工作。
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.

试了一下网上说的：

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git pull --rebase origin master
error: cannot pull with rebase: You have unstaged changes.
error: please commit or stash them.

也没用，然后试了下下面的：

You may want to first merge the remote changes (e.g., 'git pull') before pushing again.

在再次推送之前，您可能需要首先合并远程更改（例如，“git pull”）。

that is：

git pull
# Fix any merge conflicts, if you have a `README.md` locally
git push -u origin master

输入下面就通过vim进入一个文件内，我直接保存退出

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git pull

然后再push一下就好了，很迷。。

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git push -u origin master

下面是我对文件里面的README.md进行更新：

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git add README.md

Mr.Black@DESKTOP-4Q3FM6F MINGW64 /e/Sublime/python/calculate (master)
$ git commit -m "update readme"
[master 3db337d] update readme

$ git push -u origin master

就好了。
