不能在docker上用ruby / sinatra安装postgres
我正在尝试使用docker做一个tesseract api，但是在安装bundle的时候，我得到这个错误：

我只是运行一个小的单一端点的sinatra应用程序，你发送图像，它返回文本作为JSON文件，并在这一点上绊脚石。
我已经search了相当数量，并尝试了一些解决scheme，如指向configuration文件的位置，但他们似乎都给出了类似的错误。
任何帮助将是伟大的
为什么要使用ubuntu：16.04就在一开始。 我认为问题在于你的docker环境没有正确设置来运行ruby和bundler。
为了通过这个血腥的设置过程，我build议你使用具有高山或苗条标签的ruby图像，如果存储空间是一个问题。 然后安装过程变得更容易，你避免所有这些错误
