pg 0.18.4在我的开发环境中工作正常但在Heroku中没有。在本地，当我刚刚运行bundler install时它首先失败但在我手动运行gem install pg -v '0.18.4'时成功了。我尝试配置一个Heroku Postgres插件，但无济于事。
当我运行git push heroku master时，我得到以下输出：

更新：Heroku帮助即将结束。
当我创建一个新的Rails应用程序并进行部署时（相同的pg版本，没有问题。我行为不端的应用程序中的哪些文件可能导致这种不同的行为？我正在努力解决问题，但到目前为止没有这样的运气。

检查Bundler configuration。为确保您没有任何内容，请运行bundle config，并可能bundle remove <config name>。在这种情况下，如果您设置了与默认设置冲突的内容，请尝试bundle remove build.pg。
