Question

我正在尝试在Ubuntu 18.04上安装Rails＆Sinatra。我尝试了各种方法，但是每个方法都会引发某些错误。我已经尝试了gem，rbenv，apt安装，但是所有的尝试都是徒劳的。

apt install ruby-railties

引发依赖项错误。

The following packages have unmet dependencies.
 ruby-railties : Depends: rake (>= 0.8.7) but it is not installable
                 Depends: ruby but it is not installable or
                          ruby-interpreter but it is not installable
                 Depends: ruby-actionpack (= 2:4.2.10-0ubuntu4) but it is not going to be installed
                 Depends: ruby-activesupport (= 2:4.2.10-0ubuntu4) but it is not going to be installed
                 Depends: ruby-thor (< 2.0) but it is not going to be installed
                 Depends: ruby-thor (>= 0.18.1) but it is not going to be installed

gem install rails

引发以下错误，我通过禁用ipv6以及所有其他措施（但没有结果）进行了各种尝试来纠正。

ERROR:  Could not find a valid gem 'rails' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - timed out (https://rubygems.org/specs.4.8.gz)

使用gem难以安装sinatra和rails
