我一直在尝试将我的Ruby on Rails应用程序部署到Heroku，但一直遇到错误。非常感谢提前帮助！
我一直按照此链接中的说明部署我的应用：http://curriculum.railsbridge.org/intro-to-rails/deploying_to_heroku
我将我的gemfile更改为以下内容然后运行
bundle install --without production
宝石文件：
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

以下是Heroku的构建日志。它抱怨没有宝石＆＃39; pg＆＃39;在gemfile中，但我确实添加了它，也进行了bundle install。
Running: rake assets:precompile
rake aborted!
Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

###### WARNING:
You have the `.bundle/config` file checked into your repository
It contains local state like the location of the installed bundle
as well as configured git local gems, and other settings that should
not be shared between multiple checkouts of a single repo. Please
remove the `.bundle/` folder from your repo and add it to your `.gitignore` file.

Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.16.1). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

Bundle complete! 25 Gemfile dependencies, 82 gems now installed.
Gems in the groups development, test and production were not installed.
Bundled gems are installed into ./vendor/bundle.
Post-install message from paperclip:
##################################################
# NOTE FOR UPGRADING FROM 4.3.0 OR EARLIER #
##################################################
Paperclip is now compatible with aws-sdk >= 2.0.0.
If you are using S3 storage, aws-sdk >= 2.0.0 requires you to make a few small
changes:
* You must set the `s3_region`
* If you are explicitly setting permissions anywhere, such as in an initializer,
note that the format of the permissions changed from using an underscore to
using a hyphen. For example, `:public_read` needs to be changed to
`public-read`.
For a walkthrough of upgrading from 4 to 5 and aws-sdk >= 2.0 you can watch

这可能不是您想要的答案，但是您应该避免使用if (input.split('-').length > 1) {
//your code
}else {
input='$'+input;
}
进行开发，然后切换到sqlite3进行生产，因为可移植性问题和一般的头痛问题。
我建议您按以下方式重新创建应用：
pg
在开发过程中，您总是想要考虑最终产品。如果你知道你要将它部署到Heroku，那么你知道你将需要PostgreSQL，或者如果你不知道，现在就可以了。
您始终希望您的开发环境尽可能地与您的生产环境相似。
