问题描述
我正在尝试从新计算机上的项目克隆存储库中推送项目更改。我已经将Heroku添加为远程对象，而我的现有项目位于origin/branchname中，但是，当我这样做时：
git push heroku master我收到以下错误：
To https://git.heroku.com/myapp.git
! [rejected] master -> master (non-fast-forward)
error: Failed to push some refs to 'https://git.heroku.com/myapp.git'
hint: Updates were rejected because a pushed branch tip is behind its remote
hint: counterpart. Check out this branch and 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.
如何将origin/branchname上的更改推送到Heroku？在较旧的系统上，我要做的只是：git push heroku master。我还添加了我的heroku键。并遵循了以下所有步骤：How to link a folder with an existing Heroku app
编辑
我也尝试过强制推送，但出现错误：
remote: -----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/python.tgz
remote: More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
remote:
remote: ! Push Failed
remote: !
remote: ! ## Warning - The same version of this code has already been built: a83ad0723dc584575acbbfd8f5e4ed7a7e3fedaf
remote: !
remote: ! We have detected that you have triggered a build from source code with version a83ad0723dc584575acbbfd8f5e4ed7a7e3fedaf
remote: ! at least twice. One common cause of this behavior is attempting to deploy code from a different branch.

remote: ! If you are developing on a branch and deploying via git you must run:

这是因为我克隆了存储库引起的吗？
