Question

我想将我的新应用程序上传到Heroku，但我遇到了一些问题。首先，问题是SQLite，因此我删除了sqlite中的Gemfile行。另一个问题是当我在控制台中编写命令git push heroku时，我看到了这个错误：

错误：无法推送一些引用。

的Gemfile

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0'

group :production do
  gem 'pg'
  gem 'rails_12factor'
end

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password

Heroku似乎认为你的Gemfile中仍然有SQLite，根据这个错误：

Gem::Installer::ExtensionBuildError：错误：无法构建gem原生扩展。 /tmp/build_1f9f851d-1743-4e22-b574-756689adf44d/vendor/ruby-2.0.0/bin/ruby extconf.rb 检查sqlite3.h ...没有 sqlite3.h遗失了。试试'port install sqlite3 + universal'，

这可能表示您忘记将您的Gemfile和Gemfile.lock更改提交给Git：

git add Gemfile Gemfile.lock
git commit -m "Add Gemfile changes"

一旦版本化，您应该能够将更改推送到Heroku：

git push heroku <branch>

为什么在推送到Heroku时会出现“错误：无法推送一些参考”？
