Question

我的目标是在Heroku上为环境“heroku_production”部署一个应用程序。

My Gemfile如下所示：

source 'https://rubygems.org'

gem 'rails', '3.2.9'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test, :production do 
  gem 'sqlite3'
end
# This is needed in case this app is deployed in Heroku - in order to make the Heroku deployment independent from the production environment
group :heroku_production do
  gem 'pg'
end
...

我将BUNDLE_WITHOUT变量设置为“development：test：production”。这是调用heroku config --app my_app时的输出：

=== my_app Config Vars
BUNDLE_WITHOUT:             development:test:production
DATABASE_URL:               postgres://XXXXXXX....
HEROKU_POSTGRESQL_CYAN_URL: postgres://XXXXXXX....
RACK_ENV:                   heroku_production
RAILS_ENV:                  heroku_production

但是，当我将我的东西推送到Heroku时，BUNDLE_WITHOUT var未应用，因为您可以在以下错误消息中看到（第3行： - without development：test）：

       An error occurred while installing sqlite3 (1.3.7), and Bundler cannot continue.
       Make sure that `gem install sqlite3 -v '1.3.7'` succeeds before bundling.

为什么Heroku这样做？
谷歌搜索也没有帮助。

Answer 1

请注意 - 目前，Cedar堆栈不支持BUNDLE_WITHOUT。

Answer 2

我最近联系了Heroku关于这个问题，他们说BUNDLE_WITHOUT现在有用了！

以下是我得到的回复：

您好，不推荐使用user_env_compile，但是这个功能只是Ruby buildpack的默认功能 - 所以你可以使用BUNDLE_WITHOUT config var。我相信你看过这篇文章，但这是正确的吗？ https://devcenter.heroku.com/articles/bundler#specifying-gems-and-groups 好像我们需要更新该文档！最好， [姓名编辑]

尚未尝试但很快就会尝试。

在Heroku上部署应用程序时不应用BUNDLE_WITHOUT
