出现场景
要把某个项目push到码云上，已经设置了仓库地址，在最后一步直接报错。
adodeMacBook-Pro:yimabao ado$ git push --set-upstream origin master
remote: [session-774b45b9] Access denied
fatal: unable to access 'https://gitee.com/mzmilk/yimabao.git/': The requested URL returned error: 403
解决方案
打开钥匙串，种类选择所有项目，在右边搜索git。
找到github或者gitee，删除对应的项目即可。
弹出窗口，选择删除。
再重新pull或者push，会提示输入密码和账号，输入正确的就能正常pull、push了。
adodeMacBook-Pro:yimabao ado$ git push --set-upstream origin master
