如何在Docker上安装Ruby？ [英] How to install Ruby on docker?

问题描述

我试图在码头上安装红宝石。我可以安装1.9版本，但不可能安装2.2.0及更高版本的最新版本。我实际上是试图在码头上设置葫芦。已尝试此。每当我尝试安装calabash-android它得到错误

 错误：安装calabash-android时出错：
 luffa需要Ruby版本> = 2.0。

您可以从...开始查看dockerfile： p>

  FROM ruby​​：2.3.0 
  

这将使用已安装ruby的 docker image ruby​​ 。

I am trying to install ruby on docker. I could install the 1.9 versions but it is not possible to install the latest version such as 2.2.0 and above. I am actually trying to set up calabash on docker. Have tried this. Whenever I try to install calabash-android in it getting the error

ERROR:  Error installing calabash-android:
luffa requires Ruby version >= 2.0.

You could start view a dockerfile starting with:

FROM ruby:2.3.0

That would use the docker image ruby, with ruby already installed.
