在Gemfile中设置环境，以根据自定义文件捆绑安装/更新 [英] Setting the environment in Gemfile for bundling install/update based on a customize file

问题描述

所有
我建立一个sinatra应用程序，捆绑的主要文件如下，

environment.rb

  require'sinatra'
 require'sequel'
 
 ENV ['RACK_ENV'] ='development'
 
 configure：production do 
 #do something 
 end 
 
 configure：development，：test do 
 #do something 
 end 
  

Gemfile

  gem'sinatra'
 gem'sequel'
 
 gem'pg'，：group => ：制作
 gem'sqlite3'，：group => [：development，：test] 
  

所以，如何让这个bundle基于ENV [' RACK_ENV']在我的environment.rb文件中。

解决方案

在做捆绑器需求时，您可以指定需要哪些组。 / p>

例如：

  require'rubygems'
 require 'bundler'
 
如果ENV ['RACK_ENV'] =='development'
 Bundler.require（：default，：development）
 else 
 Bundler.require（ ：默认）
需要'sinatra'

hi, all I build a sinatra app, the main files for bundling as the following,

environment.rb

require 'sinatra'
require 'sequel'

ENV['RACK_ENV'] = 'development'

configure :production do
     #do something
end

configure :development, :test do
     #do something
end

Gemfile

gem 'sinatra'
gem 'sequel'

gem 'pg', :group => :production
gem 'sqlite3', :group => [:development, :test]

So, how to let the bundle install based on the ENV['RACK_ENV'] in my environment.rb file.

解决方案

When doing a bundler require you can specify which groups to be required.

For example:

require 'rubygems'
require 'bundler'

if ENV['RACK_ENV'] == 'development'
  Bundler.require(:default, :development)
else
  Bundler.require(:default)
require 'sinatra'
