我用gem'sqlite3'，'〜＆gt;替换了sqlite3 gem。 1.3.0'并运行bundle install但它没有做任何事情。我也尝试过安装他们错误建议的替代方案，但它也会抛出错误

ERROR:  Could not find a valid gem 'activerecord-sqlite3-adapter' (>= 0) in any
repository
ERROR:  Possible alternatives: activerecord-jdbcsqlite3-adapter, activerecord-sq
lserver-adapter, activerecord-bq-adapter, activerecord-simpledb-adapter, activer
ecord-mysql2-adapter

有人知道如何解决这个问题吗？

Gemfile是

source 'https://rubygems.org'

gem 'rails', '3.2.13'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3', '~> 1.3.0'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

Answer 1

这就是我解决问题的方法。

我使用rails installer重新安装了rails，ruby，devkit。现在工作得很好。

使用rails server启动服务器出错，sqlite错误
