我使用的版本：

• Ruby: 2.5.0-p0
• Rails: 5.2.0.rc1
• Homeland: 3.0.11

好的，谢谢！

已解决。我内存配置小的缘故。

could not translate host name "postgresql" to address: Name or service not known Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"utf-8", "database"=>"homeland", "username"=>"postgres", "password"=>"vagrant", "host"=>"postgresql", "port"=>5432, "pool"=>64} rails aborted!

postgresql 需要另外搭建吗？还是使用 sudo make install 时就会创建 postgresql 实例并启动？

我搭建好了，但是使用连不上 postgresql，谁能帮忙看看吗？用的环境是 vagrant + ubuntu 16.04。执行 sudo make install 时，报如下错误：

@huacnlee https://gethomeland.com/install/ 这个文档是针对 14.04 的，我如果用 16.04 可以吗？还是这个脚本：curl -sSL https://git.io/install-docker | bash 吗？

好的，谢谢大佬。

哈哈，已笑尿。。

+1，你们都是分母~
