当我想将我的应用程序部署到 heroku(使用 git push heroku master)时,它给了我一个错误并告诉我安装 sqlite3 -v '1.3.6'。因此,在成功安装该 gem 后,我尝试再次将其部署到 heroku,但它仍然给我同样的错误!但是,我已经安装了它。现在我什至无法在本地运行我的 rails 项目(rails 服务器)。我可以知道这可能是什么原因吗?

这是我在 database.yml 文件中的内容:

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: sqlite3
  database: db/production.sqlite3
  pool: 5
  timeout: 5000

让你的 gemfile 看起来像这样

      group :production do
         gem 'pg'
      end
      group :development, :test do
         gem 'sqlite3-ruby', :require => 'sqlite3'
      end

Heroku 不适用于SQLite3

打开您的 Gemfile 并替换以下行:

gem 'sqlite3'

为了

group :production do
  gem 'pg'
end

group :development, :test do
  gem 'sqlite3'
end

我还建议您阅读 heroku 说明:https ://devcenter.heroku.com/articles/rails3
