[英]An error occurred while installing pg (0.18.2), and Bundler cannot continue
遵循Tony Coconate的Rails + Ember.js(帶有Ember CLI)教程之后,我們嘗試創建一個新的Rails API。
當我們運行rails new api -T -d postgresql
,我們收到以下錯誤消息:
An error occurred while installing pg (0.18.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.2'` succeeds before bundling.
這就是Gemfile
文件的樣子:
source "https://rubygems.org"
gem "rails", "4.2.1"
gem "activeadmin", github: "gregbell/active_admin" # Until it"s 1.0.0
gem "coffee-rails", "~> 4.0.0"
gem "devise"
gem "grape"
gem "grape-active_model_serializers"
gem "grape-swagger-rails"
gem "jquery-rails"
gem "pg"
gem "rack-cors", require: "rack/cors"
gem "sass-rails", "~> 4.0.3"
gem "uglifier", ">= 1.3.0"
group :development do
gem "better_errors"
gem "meta_request"
gem "quiet_assets"
gem "spring"
end
group :development, :test do
gem "capybara"
gem "capybara-screenshot"
gem "database_cleaner"

gem "pry-rails"
gem "pry-stack_explorer"
gem "pry-theme"
gem "rspec-rails"
gem "rubocop"
gem "shoulda-matchers"
gem "spring-commands-rspec"
end
運行bundle install
,出現以下錯誤消息:

當我們運行gem install pg -v '0.18.2'
,我們還會得到一個錯誤:

關於錯誤的任何想法,最重要的是,我們如何解決它?
顯示錯誤,表明捆綁程序無法訪問psql
二進制文件
您可以按照其他答案中的建議安裝postgresql
。 但是,如果您正在使用http://postgresapp.com/中的Postgres.app
,則只需在~/.bash_profile
文件中添加以下行來設置$PATH
:
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin
