Rails和Postgres - 在部署heroku时忽略pg gem [英] Rails and postgres - pg gem ignored during deploy on heroku

问题描述

我在我的应用上部署heroku时遇到问题。我已经给Gemfile添加了'pg'gem，甚至尝试添加诸如gem'therubyracer-heroku'之类的东西。
期间

  heroku rake db：migrate 
  

我得到这样的东西：

 > heroku rake db：migrate 
 --trace 
 **调用db：migrate（first_time）
 **调用环境（first_time）
 **执行环境
 rake中止！ 
请安装postgresql适配器：`gem install activerecord-postgresql-adap 
 ter`（pg不是bundle的一部分，将它添加到Gemfile中）
 /app/.bundle/gems /ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connectio 
 n_adapters / abstract / connection_specification.rb：71：在`rescue in establish_conne 
 ction'
  

另一个有趣的部分是，在捆绑安装操作期间未提及heroku pg，就像忽略它一样。我也看过Gemfile.lock和pg在那里提到：

  pg（0.11.0-x86-mingw32）
  

我不知道这是否是导致heroku忽略pg gem或什么的Windows gem问题？

任何人都可以帮忙或者有类似的问题吗？

似乎相关：在此处输入链接描述

并且看起来难以解决

解决方案

postgres to your production group;

  group：production do 
 gempg
 end 
  

重新绑定

  bundle  - 没有生产
  

并提交到git（Gemfile和Gemfile.lock）并推送到Heroku 。这应该可以解决你的问题。

I have trouble deploying my app on heroku. I have added 'pg' gem to Gemfile, and even try to include something like gem 'therubyracer-heroku'. during

heroku rake db:migrate

I get something like this:

>heroku rake db:migrate
 --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adap
ter` (pg is not part of the bundle. Add it to Gemfile.)
/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connectio
n_adapters/abstract/connection_specification.rb:71:in `rescue in establish_conne
ction'

Another interesting part is that while pushing to heroku pg is not mentioned during bundle install operation like if it was ignored. I also watched the Gemfile.lock and pg is mentioned there to:

pg (0.11.0-x86-mingw32)

I wonder if it is a Windows gem issue that cause heroku to ignore the pg gem or something ?

Can anyone help or had similar problem ?

//EDIT

Seems related: enter link description here

And looks unsolveable

解决方案

In your Gemfile limit postgres to your production group;

group :production do
  gem "pg"
end

rebundle

bundle --without production

and commit to git (Gemfile and Gemfile.lock) and push to Heroku. That should solve your problem.
