我正在尝试在我的本地系统上运行来自https://github.com/helpyio/helpy的克隆Helpy应用程序。已完成Docker和docker-compose安装。
如果我运行rails s，则会显示Could not find proper version of railties (4.2.10) in any of the sources
Run捆绑安装to install missing gems.
如果我运行bundle install，则会显示An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that "gem install pg -v '0.18.4'" succeeds before bundling.
现在我该如何运行这个应用程序？请帮我。
如果我的localhost需要更改配置文件或是否需要任何其他安装，请告诉我？
