当我想将我的应用程序部署到heroku时(使用git push heroku master),它会给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之后,我尝试将其再次部署到heroku,它仍然给我同样的错误!但是,我已经安装了它。现在我甚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'
代表
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end
