Question

我是Ruby on Rails的新手，每次将git文件推送到Heroku时都会遇到错误信息。

我采取的步骤是：

heroku登录
heroku键：添加
heroku create
git push heroku master

错误消息如下：

           Could not detect rake tasks
           remote:  !     ensure you can run `$ bundle exec rake -P` against   your app
           remote:  !     and using the production group of your Gemfile.
           remote:  !     rake aborted!

          Push rejected, failed to compile Ruby app
          remote:
          remote: Verifying deploy...
          remote:
          remote: !       Push rejected to project1-app.
          remote:
          To https://git.heroku.com/project1-app.git
          ! [remote rejected] master -> master (pre-receive hook declined)
          error: failed to push some refs to 'https://git.heroku.com/project1-app.git'

看起来你没有更新你的包可能是在gem文件中进行一些编辑之后。为了使您的软件包与当前的gem文件保持同步，请在命令

下运行

（1）bundle install

（2）bundle update

一旦您的软件包更新，您就可以运行

（3）heroku login

（4）heroku create

（5）git add .

（6）git commit -am "some comment"

（7）git push heroku master

（8）heroku open

无法将Git文件推送到Heroku
