在Heroku上部署应用程序时不应用BUNDLE_WITHOUT

Question

我的目标是在Heroku上为应用程序'heroku_production'部署应用程序。

我的Gemfile看起来是这样的：

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 
... 

我设置BUNDLE_WITHOUT变量 “发展：测试：生产”。下面是调用heroku config --app my_app当输出：

=== 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，当我把我的东西的Heroku没有应用BUNDLE_WITHOUT var当成你可以在下面的错误信息看（3号线：--without发展：测试）：

     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会这么做？
谷歌搜索没有帮助。

请注意 - 目前，Cedar堆栈不支持BUNDLE_WITHOUT。

Answer 2

我最近接触的Heroku了这个问题，他们说，现在BUNDLE_WITHOUT工作！

这是我得到的回应：

嗨， user_env_compile已过时，但这一功能，只需成为默认为Ruby buildpack - 所以你可以使用BUNDLE_WITHOUT配置变种。 我相信你看到了这篇文章，但是这是否正确？ https://devcenter.heroku.com/articles/bundler#specifying-gems-and-groups 似乎我们需要更新该文档！ 最佳， [节录名]

有不尽快尝试过，但会。
