由于以下错误，我在运行rails server命令时遇到困难：
为数据库适配器指定了“ sqlite3”，但未加载gem。将
gem 'sqlite3'添加到您的Gemfile中（并确保其版本为ActiveRecord要求的最低版本）。 （Gem :: LoadError）
我在Google中找到了几个答案（Changing Sqlite3 to Postgresql Rails，Ruby on Rails - “Add 'gem sqlite3'' to your Gemfile”，Add ‘gem sqlite3” to your Gemfile ...），但是这些答案都不适合我。我尝试手动更改gemfile.lock的值，尝试运行bundle命令，但仍然遇到相同的错误。此外，我在sqlite3组的gemfile中确实有:development, :test。
macOS Mojave Version 10.14.4 Beta sqlite3版本：1.4.0 pg版本：0.20 PS：我正在使用pg gem，以便在heroku上使用数据库。
这是我的gemfile，请注意，一些gems已删除，以使列表看起来更小，更整洁：
group :production do
# Database
gem 'pg', '~> 0.20'
gem 'rails_12factor'
end
group :development, :test do
gem 'sqlite3'
gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
gem 'capybara', '~> 2.13'
gem 'selenium-webdriver'

通过更新gemfile.lock
将sqlite3 (1.4.0)更改为sqlite3 (1.3.13)。
更新：
不要忘记在gemfile中指定您的gem版本。
例如：gem 'sqlite3', '~> 1.3.13'，否则bundle update命令将返回此错误。

在Gemfile中将sqlite3更改为sqlite3 (1.3.13)之后，我也运行了它，之后我运行了bundle update
在Gemfile中：gem 'sqlite3', '~> 1.3.13'
之后，我设法到达了耶！您正在使用Rails！页面
