我正在尝试使用bundle install:
在Michael Hartl的教程中安装这个gem文件source 'https://rubygems.org'
gem 'rails', '4.2.2'
gem 'bcrypt', '3.1.7'
gem 'faker', '1.4.2'
gem 'carrierwave', '0.10.0'
gem 'mini_magick', '3.8.0'
gem 'fog', '1.26.0'
gem 'will_paginate', '3.0.7'
gem 'bootstrap-will_paginate', '0.0.10'
gem 'bootstrap-sass', '3.2.0.0'
gem 'sass-rails', '5.0.2'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
group :development, :test do
gem 'sqlite3', '1.3.9'
gem 'byebug', '3.4.0'
gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
group :test do
gem 'minitest-reporters', '1.0.5'
gem 'mini_backtrace', '0.1.3'
gem 'guard-minitest', '2.3.1'
end
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
gem 'puma', '2.11.1'
end
我在终端上运行bundle install
。我有这个错误:
Bundler could not find compatible versions for gem "actionpack":
In snapshot (Gemfile.lock):
actionpack (= 4.2.4)
In Gemfile:
railties (>= 0) ruby depends on
actionpack (= 4.2.4) ruby
web-console (>= 0) ruby depends on
sprockets-rails (< 4.0, >= 2.0) ruby depends on
actionpack (>= 3.0) ruby
rails (= 4.2.2) ruby depends on
actionpack (= 4.2.2) ruby
actionpack (>= 0) ruby
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
对于这里真正发生的事情有任何线索吗?我尝试了捆绑更新,它提示我:An error occurred while installing pg (0.17.1), and Bundler cannot continue. Make sure that
gem install pg -v'0.17.1'succeeds before bundling.
然后,如果我安装了pg,它仍然不会这样做......

该教程中的生产块面向Heroku,您需要执行以下操作:
bundle install --without production
因为您当地的宝石集并不需要那些宝石。

当您学习Rails时,您可能不打算将Michael Hartl的教程应用程序推向生产阶段。只需删除此块:
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
gem 'puma', '2.11.1'
end
通过这种方式&#39;&#39;不需要宝石。仅当您想使用postgresql服务器在生产中运行应用程序时才可以。
然后运行bundle update,它应该可以正常工作。

在Linux上,安装这两个
sudo apt-get install postgresql
sudo apt-get install pgadmin3
bundle install
那对我有用
