github更新文件

克隆仓库到本地

git clone 这里写仓库地址

如果已经配置SSH key，克隆的时候仓库地址记得选SSH地址

更新文件

进入项目所在本地文件夹，右键-git bash here
git add . （全部文件）
git add filename (需要更新的文件名称)
git commit -m "提交信息"
git push -u origin main

如果报错： Updates were rejected because the remote contains work that you do hint: not have locally.
则需要先git pull，再push

报错：Your configuration specifies to merge with the ref 'refs/heads/master'

from the remote, but no such ref was fetched.

解决办法：
git init

报错：‘origin‘ does not appear to be a git repository

解决办法：
git remote add origin 这里写git仓库地址

报错： 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.
解决办法：
先pull再push：
git pull
会提示：Please enter a commit message to explain why this merge is necessary
解决办法：
可以直接下面3,4步退出黑框。如果要输入解释的话就需要1-4步:
1.按键盘字母 i 进入insert模式
2.修改最上面那行黄色合并信息,可以不修改
3.按键盘左上角"Esc"
4.输入":wq",注意是冒号+wq,按回车键即可
