无法推送新轨到heroku数据库错误

Question

我想推我的应用程序到heroku。

我Gemfile看起来像下面

source 'https://rubygems.org' 

git_source(:github) do |repo_name| 
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/") 
"https://github.com/#{repo_name}.git" 
end 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '~> 5.0.1' 
# Use sqlite3 as the database for Active Record 
    gem 'sqlite3' 
# Use Puma as the app server 
    gem 'puma', '~> 3.0' 
# Use SCSS for stylesheets 
    gem 'sass-rails', '~> 5.0' 
# Use Uglifier as compressor for JavaScript assets 
    gem 'uglifier', '>= 1.3.0' 
# Use CoffeeScript for .coffee assets and views 
    gem 'coffee-rails', '~> 4.2' 
# See https://github.com/rails/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library 
    gem 'jquery-rails' 
# Turbolinks makes navigating your web application faster. Read more: https://github.com/turbolinks/turbolinks 
    gem 'turbolinks', '~> 5' 
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder 
    gem 'jbuilder', '~> 2.5' 
# Use Redis adapter to run Action Cable in production 
    # gem 'redis', '~> 3.0' 
# Use ActiveModel has_secure_password 
    # gem 'bcrypt', '~> 3.1.7' 

# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 

group :development, :test do 
# Call 'byebug' anywhere in the code to stop execution and get a debugger console 
    gem 'byebug', platform: :mri 
end 

group :development do 
# Access an IRB console on exception pages or by using <%= console %> anywhere in the code. 
    gem 'web-console', '>= 3.3.0' 
    gem 'listen', '~> 3.0.5' 
# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 
    gem 'spring' 
    gem 'spring-watcher-listen', '~> 2.0.0' 
end 

# Windows does not include zoneinfo files, so bundle the tzinfo-data 
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby] 

gem 'pg' 

我不能当我做git push heroku master推。

下面是我得到

gem::Ext::BuildError: ERROR: Failed to build gem native extension.

对不起，这个问题的穷人格式，请建议我错过了什么错误。

Answer 1

将gem pg加到heroku上，因为在heroku上使用了posgres。

或做到这一点：

的Gemfile

gem 'sqlite3', group: :development 
gem 'pg', group: :production 

然后

bundle install 

，推动Gemfile和Gemfile.lock到Heroku的
