Question

使用Dokku 0.5.3，我在部署Ruby / Rack应用程序时遇到问题：Bundler没有在B组中安装我的宝石。

这是我的Gemfile：

:production

这是我将回购推送给dokku时的输出：

source 'https://rubygems.org'

ruby '2.3.0'

gem 'bundler'
gem 'sinatra'
gem 'sinatra-contrib'
gem 'json'
gem 'thin'
gem 'instagram'
gem 'data_mapper'
gem 'dm-types',
  :git => 'git://github.com/julienma/dm-types.git',
  :branch => 'gem-v1.2.2-with-frozen-nilclass-fix'

gem 'dm-postgres-adapter', :group => :production

group :development, :test do
  gem 'dm-sqlite-adapter'
  gem 'dotenv'
  gem 'pry'
end

ruby错误是因为它不需要Counting objects: 114, done. Delta compression using up to 4 threads. Compressing objects: 100% (91/91), done. Writing objects: 100% (114/114), 13.76 KiB | 0 bytes/s, done.

以下是我所知道的：

我的本地Gems in the groups development, test and production were not installed.包含.bundler/config，但这是BUNDLE_WITHOUT: production＆＃39; d。
在dokku实例上，这是.gitignore给我的：
```
dokku run my-app bundle config
```

我可以理解Settings are listed in order of priority. The top value will be used. without Set for your local app (/app/.bundle/config): "development:test:production" Set via BUNDLE_WITHOUT: "development:test" Set for the current user (/app/.bundle/config): "development:test:production" ...条款的development:test来自何处，但我真的很想知道without是如何以及为何也存在。

我还尝试在第一次部署之前设置ENV var production 。它被考虑在内，但它之前是本地捆绑包配置，它已经排除了BUNDLE_WITHOUT: development:test。

我通过手动修改production并删除/home/dokku/my-app/cache/.bundle/config：
解决了这个问题
production

再次推送后，Bundler成功安装了我的BUNDLE_WITHOUT: development:test宝石。

但我不想手动编辑服务器上的配置文件以使其正常工作。

所以，问题：

为什么在Dokku上部署时，Bundler会忽略production组？

如何强制安装production宝石？

谢谢！

我们使用heroku buildpack，因此最新的buildpack可能存在设置正确默认值的问题吗？

在Dokku上部署ruby应用程序：为什么Bundler配置强制＆＃34;没有生产＆＃34;？
