sqlite - Heroku 正在尝试安装 sqlite3 gem，即使它不在 Gemfile 中

Question

我第一次尝试在 Heroku 上部署 Rails 3.1 应用程序。我将它设置为 Cedar 堆栈，删除了 sqlite3 gem，但是当我将代码推送到 Heroku 时，出现此错误:

-----> Installing dependencies using Bundler version 1.1.rc Running: bundle install --without development:test --path vendor/bundle --deployment Fetching gem metadata from http://rubygems.org/....... (...)

Installing rails (3.1.0) Installing sqlite3 (1.3.4) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks! /usr/local/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError) /usr/local/bin/ruby extconf.rb checking for sqlite3.h... no

我不知道为什么 bundle install 会尝试安装 sqlite3。看看我的 Gemfile 和 Gemfile.lock:

gem 文件

source 'http://rubygems.org'

gem 'rails', '3.1.0'

gem 'json'
gem 'pg'
gem 'thin'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
#  gem 'sass-rails', "  ~> 3.1.0"
#  gem 'coffee-rails', "~> 3.1.0"
  gem 'uglifier'
end

gem 'jquery-rails'

Gemfile.lock

我该如何解决？

Answer 1

当我遇到这个问题时，结果是我忘记在 bundle install 之后提交我的更改。呸! git status 应该指示 gem 文件的未暂存更改。
