Question

我正在使用Travis CI来测试我的Rails项目。在构建我的提交时，它会在bundle exec rake上停止。

Your bundle is complete!
It was installed into ./vendor/bundle
Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
$ psql -c 'create database travis_ci_test;' -U postgres
CREATE DATABASE
$ cp config/database.yml.travis config/database.yml
$ bundle exec rake
rake aborted!
Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

（如您所见，没有安装pg gem。）

我的.travis.yml：

language: ruby
rvm:
  - "2.0.0"
addons:
  postgresql: "9.3"
before_script:
  - psql -c 'create database travis_ci_test;' -U postgres
  - cp config/database.yml.travis config/database.yml

我的Gemfile：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.4'
# Use postgresql as the database for Active Record
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# 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
# gem 'therubyracer',  platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0',          group: :doc

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

gem 'rails_12factor', group: :production
ruby "2.0.0"

所以'pg'gem是在Gemfile中，它可以在我的电脑上运行，但是Travis没有安装它。

Answer 1

Gemfile.lock文件中的'pg'gem？如果没有，您可能需要删除此文件并通过再次运行bundle install重新生成它。

Answer 2

从存储库中删除Gemfile.lock，现在构建和测试正在按预期工作。

我想这是因为在Windows上创建了锁文件，并且它包含一些特定于平台的内容（如gems的mingw32后缀）

特拉维斯CI找不到'pg'宝石
