1.初始化项目

git init

2.建立本地仓库和远程仓库的连接

git remote add origin 远程仓库URL

ps：移除git仓库连接可使用 git remote remove origin

3.将码云上的仓库pull到本地

git pull origin 分支名称

4.创建并切换分支，这里和远程仓库的分支要一致（选择指定推送的分支，使用git branch可以查看分支）

git checkout -b 分支名称

5.将文件加载到暂存区

git add .

ps：add错了可以使用git rm --cached 文件名 删除对应的文件

6.将文件提交到本地仓库（-m 描述信息）

git commit -m "上传说明，资源描述"

7.将本地仓库推送到远程仓库

git push origin 分支名称

git remote add 仓库名 仓库地址 # 仓库名自定义 例如:origin

4.查看仓库名.
git remote # 查看远程仓库的仓库名,加-v 查看仓库名和地址

5.更改远程仓库地址.
git remote ser-url 仓库名 仓库地址

6.将文件添加添加到暂存区.
git add . # . 代表所有,可以指定为具体文件

7.将暂存区中的文件提交到本地仓库.
git commit -m "注说明"

8.查看所有分支.
git branch # 查看本地分支,加-a查看本地分支和远程分支,结果列表中前面标*标识当前使用分支.

9.创建分支.
git branch 分支名称

10.切换分支.
git checkout 分支名称

11.将本地仓库的文件推到远程仓库.

常见错误
1.提交缓存区中内容到本地仓库
1.1.报错信息如下:
D:\xx\xx>git commit -m"初始化"

*** Please tell me who you are.

Run

 git config --global user.email "[email protected]"
 git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'admin@DESKTOP-NHBTH4U.(none)')

1.2.报错原因:
出现错误的原因是因为无用户信息
1
1.3.解决方案:

1.添加你的邮箱

git config --global user.email "xxxx@qq.com"

2 添加你的昵称

git config --global user.name "name"

2.本地仓库提交至远程仓库时
2.1.报错信息如下:
D:\xxx\xxx>git push origin master
To https://gitee.com/xxx/xxx.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://gitee.com/xxx/xxx.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

2.2.报错原因:
出现错误的主要原因是gitee中的README.md文件不在本地代码目录中

2.3.解决方案:

1.合并代码

git pull --rebase origin master

2.再次提交

git push origin master
