Gem::LoadError:
**strong text**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).
我在 gem 文件中加載了這個:
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

我運行了 bundle install -without production 。 這是行不通的。 不知道我哪里出錯了。
在您的 gemfile 中指定 pg 的版本。 我曾經收到同樣的錯誤,這條線對我有用。
gem 'pg', '~> 0.18'
而不僅僅是 gem 'pg'
移動線
gem 'pg'
外部group :production
所以 gem 將安裝在任何類型的環境中
