分为两种方式上传：http和ssh
我先采用的ssh，遇到问题之后，改为用https方式

1.先在github上新建一个project
2.在pc上生成ssh key复制到github上。具体生成过程参考：

在git push -u origin master的时候报错：
ERROR: Repository not found. fatal: Could not read from remote repository. Please make sure you have the correct access rights
后改为https方式，参考：

输入密码时要输出token，参考：https://blog.csdn.net/weixin_41010198/article/details/119698015
