heroku - 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“heroku_production”环境部署应用。

我的 Gemfile 看起来像这样:

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”。以下是调用 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 没有应用，正如您在以下错误消息中看到的那样(第 3 行:--without development:test):

       location where your sqlite3 shared library is located).
       *** extconf.rb failed ***

       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.

Heroku 为什么要这样做？
谷歌搜索也没有帮助。

Please note - for the time being, the Cedar stack does not support BUNDLE_WITHOUT.
