您好，我正在嘗試將 sinatra 存盤庫推送到 dokku，但每次都出現此錯誤
耙中止！LoadError：加載“sqlite3”Active Record 配接器時出錯。缺少它所依賴的寶石？sqlite3 不是捆綁包的一部分。將其添加到您的 Gemfile。
似乎環境檔案上的這個配置導致了這個問題
ActiveRecord::Base.establish_connection(
adapter: "sqlite3",
database: "db/#{ENV["SINATRA_ENV"]}.sqlite"
)
這是檔案
ENV["SINATRA_ENV"] ||= "development"
require "bundler/setup"
Bundler.require(:default, ENV["SINATRA_ENV"])
require "rack-flash"
require "sinatra/json"
require "sprockets"
require "friendly_id"
ActiveRecord::Base.establish_connection(
adapter: "sqlite3",
database: "db/#{ENV["SINATRA_ENV"]}.sqlite"
)
# Load initializers
Dir["./config/initializers/**/*.rb"].each { |file| require file }
require_all "app"
我將 sqlite gem 放入開發組
group :development do
gem "letter_opener"
gem "sqlite3"
end
我已經嘗試過 rails_12factor 和 therubyracer 但問題仍然存在，有人知道為什么會這樣嗎？
放入gemfile
gem 'rails_12factor'
gem 'therubyracer'
資料庫.yml
# SQLite. Versions 3.8.0 and up are supported.
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#

uj5u.com熱心網友回復：
只需在 environment.rb 上設定環境資料庫
configure :development do
ActiveRecord::Base.establish_connection(
adapter: "sqlite3",
database: "db/#{ENV["SINATRA_ENV"]}.sqlite"
)
end
