无法在heroku上启动rails应用程序
无法在heroku上启动rails应用程序
提问于 2010-02-20 22:37:13
我正在尝试将rails应用程序部署到heroku，但一直收到以下错误。我原以为管理postgres gem应该是heroku要处理的事情。
除了在我的本地机器上安装postgres之外，我已经尝试了所有我能想到的方法，如果我想安装postgres gem，我需要这样做。也没有叫做activerecord-postgresql-adapter的宝石。我猜这是rails附带的标准适配器？？
对如何解决这个问题有什么想法吗？

事实证明这是一个错误，因为heroku和我的机器上运行着不同版本的bundler。我已经切换到使用.gems依赖文件，一切似乎都正常。

Upgrade your Gemfile to Bundler 0.9并添加pg gem。就这么简单。

有关Heroku的捆绑器支持的详细信息，请访问：http://docs.heroku.com/bundler
Heroku要求您指定'pg‘gem。
