提问by Katie H
I'm trying to push my rails app to Heroku, and I keep getting the following error:
我正在尝试将我的 rails 应用程序推送到 Heroku，但我不断收到以下错误：
An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before bundling.

Here is what my gemfile looks like:
这是我的 gemfile 的样子：
group :devlopment, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
Any ideas on how to fix this? Any help is much appreciated!

I have modified the gem file to use sqlite only on development, and test.
我已将 gem 文件修改为仅在开发和测试中使用 sqlite。
But, my mistake was: I have forgotten to commit the changes on git.
但是，我的错误是：我忘记在 git 上提交更改。

You have a typo:
你有一个错字：
group :development, :test do # <<<< :development, not devlopment
gem 'sqlite3'
end
As heroku ignores development specific gems, when running the bundle it includes sqlite3 gem.
由于 heroku 忽略特定于开发的 gem，因此在运行包时它包含 sqlite3 gem。

gem 'pg', '0.15.1'
