Question

我不断得到一个

remote:        An error occurred while installing sqlite3 (1.3.11), and Bundler cannot
remote:        continue.
remote:        Make sure that `gem install sqlite3 -v '1.3.11'`  succeeds before bundling.

尝试部署到Heroku时出现

错误，到目前为止我已尝试过所有溢出问题。

这是我的宝石文件

end

这是我的.yml

default: &default
  adapter: sqlite3
  pool: 5
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
  database: db/production.sqlite3

我在想与我的.yml有关但我真的不知道。我可以在本地运行它，但是当我真的

时

git push heroic master

我收到了这个错误

Answer 1

这里的解决方案是： https://devcenter.heroku.com/articles/sqlite3

您需要在生产环境中使用postgresql。 sqlite3不受支持所以要么将适配器更改为postgresql 或者将sqlite3添加到开发和测试组并将postgres添加到生产组

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

group :production do
  gem 'pg'
end

并将您的database.yml更改为：

# config/database.yml
default: &default
  pool: 5
  timeout: 5000

development:
  <<: *default
  adapter: sqlite3
  database: db/development.sqlite3

test:
  <<: *default
  adapter: sqlite3
  database: db/test.sqlite3

production:
  <<: *default
  adapter: postgresql
  host: localhost
  database: production
  username: postgres
  password: password

Answer 2

You cannot use SQLite3 on Heroku.用PostgreSQL替换SQLIte3，并更新你的Gemfile。

# replace gem "sqlite3" with
gem "pg"

您只需要更新开发和测试数据库配置。在生产中，database.yml文件由Heroku自动更新。实际上，您甚至不必将其提交到您的存储库。
