问题描述
我在Heroku上部署了一个非常简单的示例rails应用程序时遇到问题。这个应用程序使用数据库。
在使用sqlite3的本地（OSX）中没有问题，但我无法推送到Heroku，因为有些sqlite3丢失了引用。 p>
我已经把Gemfile放在了测试，开发和生产环境之间的区别：
#gem'sqlite3' group：development，：test do gem'sqlite3' end group：production do gem'pg'结束以及捆绑带问题：
bundle install --without production但是当我部署到Heroku：
git push heroku master我得到了一些对sqlite3的引用，并且得到一个错误。
我试过用我的OSX安装postgresql，在Gemfile上只包含gem'pg'，但我也有对sqlite3的引用。
我应该怎么做？我在Heroku上需要一些额外的配置来使用postgre db？
这是我在git推送给heroku master时获得的常见错误：

我解决了这个问题。这是一个糟糕的使用git。
我需要更新Gemfile和Gemfile.lock中的更改：首先编译：
$ bundle然后：
$ git add Gemfile $ git add Gemfile.lock $ git commit -m'添加pg适配器gem' $ git push heroku master现在Heroku更新OK
现在运行postgresql数据库：
$ heroku运行rake db：migrate再见！
I've got a problem deploying a very simple example rails app on Heroku. This app uses a db.
In local (OSX) with sqlite3 there is no problem, but I can't push to Heroku because some lost reference to sqlite3.
I've put on Gemfile the distinction between test, development and production environments:
#gem 'sqlite3' group :development, :test do gem 'sqlite3' end group :production do gem 'pg' endand bundle withou problem:
bundle install --without productionBut when i deploy to Heroku:
git push heroku masterI've got some reference to sqlite3 and get an error.
I've tryed with postgresql installed on my OSX, and bundle with only "gem 'pg'" on Gemfile, but i've got also the reference to sqlite3
What should I do? I need some extra config on Heroku to use a postgre db?
This is the common error I obtain when git push to heroku master:
git push heroku master Counting objects: 87, done. Delta compression using up to 2 threads. Compressing objects: 100% (76/76), done. Writing objects: 100% (87/87), 30.32 KiB, done.

I've resolved the problem. It was a bad use of git.
I needed to update the changes in Gemfile and Gemfile.lock:
First compile:
$ bundlethen:
$ git add Gemfile $ git add Gemfile.lock $ git commit -m 'Added pg adapter gem' $ git push heroku masterNow Heroku updates OK
And now run the postgresql database:
$ heroku run rake db:migrateBye!
