我正在尝试将我的Ruby on Railswebbapp 部署到 Heroku。在本地它工作得很好，但是当我尝试通过 Heroku 运行它时，它给了我一个 H10 错误 HTTP 状态 503。我猜这是因为bash: bundle: command not found. 但即使跑步heroku run bundle exec rails server -p $PORT也行不通。

我看到你有 3 个问题Gemfile：

  1. 您已经在组中定义gem 'therubyracer'了ruby子句assets，然后将其重新定义为生产环境，并在没有子句的情况下暂存环境。那就是不一致。

  2. 您已经重新定义ruby了生产环境和暂存环境的版本。那是错误的，因此 heroku 无法找到包含bundle可执行文件的捆绑 gem。

  3. 您的日志显示了一些记录：

    您的 Gemfile 不止一次列出了 gem rails_12factor (>= 0)。您可能应该只保留其中一个。虽然现在这不是问题，但如果您稍后仅更改其中一个的版本，则可能会导致错误。

    这是不正确的，所以要修复它，从生产gem 'therubyracer', '0.12.1'组中删除，并gem "qrencoder","~> 1.4.1"从 -*production/staging_ 组中删除，然后从同一组中删除。然后 issue ， next不是必需的，然后将生成的Gemfile和Gemfile.lock添加到 git repo，然后提交，然后执行 git push。gem 'rails_12factor'ruby "2.3.0"bundle installbundle update
