Postgress错误-捆绑安装

问题描述

当我运行

 $ bundle install 

时，我正在heroku上运行该项目，因此我不得不切换到postgress。由于某些原因，我一直收到此错误。

在安装pg（0.15.1）时发生错误，Bundler无法继续
。 
捆绑之前，请确保 gem安装pg -v'0.15.1'成功。

解决方案
从您的Gemfile中看来，您正在使用sqlite3进行开发，而使用postgres进行生产。您无需在本地安装postgres。只需在没有生产组的情况下进行捆绑安装即可：
 捆绑安装-不生产
  
 
When I run 
$bundle install
 I am running the project on heroku so I had to switch to postgress. I keep getting this error for some reason. 
An error occurred while installing pg (0.15.1), and Bundler cannot
continue.
Make sure that gem install pg -v '0.15.1' succeeds before bundling.

 解决方案 
From your Gemfile it seems that you are using sqlite3 for development and postgres for production. You don't have to install postgres locally. Just do bundle install without production group:
bundle install --without production
