推到heroku，但没有改变应用程序？ [英] pushed to heroku but no changes to app?

问题描述

我使用以下三个命令将更改推送到已经存在的应用程序，但更改没有被反映出来

  $ git add。 
 $ git commit -mchanges
＃在分支大师
＃你的分支在2次提交之前领先于origin / master。 
 $ git push heroku master 
  

我得到：

 至[e-mail]：sleepy-oasis-7771.git！ [被拒绝] master  - > master（非快速转发）
错误：未能将某些文件推送到'[e-mail]：sleepy-oasis-7771.git'
为了防止您失去历史记录，正向更新被拒绝
在再次推送之前合并远程更改（例如'git pull'）。有关详细信息，请参阅git push --help的快速转发部分的
'注意事项。 
  

并且没有变化反映在应用程序中

解决方案

您的推送是！ [拒绝] 。

消息指出：

 为了防止您丢失历史记录，拒绝非快进更新
在再次推送之前合并远程更改（例如'git pull'）。有关详细信息，请参阅git push --help的快速转发部分的
'注意事项。 
  

这表示您可以在本地机器上看到更多文档，或者在线。同样，正如消息所示， git pull （及其产生的合并）将解决此问题。

一避免此问题的方法是使用重建工作流程而不是合并工作流程。在功能分支中进行开发，当你准备好合并时，拉大师，重新绑定功能分支，重新运行测试套件，然后然后合并。

另外，请阅读您的错误消息。

I used the following three commands to push the changes to an already existing app but the changes are not being reflected

$ git add .
$ git commit -m "changes"
# On branch master
# Your branch is ahead of 'origin/master' by 2 commits.
$ git push heroku master

And I get:

To [e-mail]:sleepy-oasis-7771.git ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to '[e-mail]:sleepy-oasis-7771.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again.  See the
'Note about fast-forwards' section of 'git push --help' for details.

and no changes are reflected in the app

解决方案

Your push was ! [rejected]. That's why no changes take effect.

As the message indicates:

To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again.  See the
'Note about fast-forwards' section of 'git push --help' for details.

This refers you to further documentation, visible on your local machine or online. Again, as the message indicates, a git pull (and its resulting merge) will fix this issue.

One way to avoid this problem is by using a rebase workflow instead of a merge workflow. Do your development in a feature branch, and when you're ready to merge, pull master, rebase the feature branch, re-run your test suite, and then merge.

Also, please read your error messages.
