为SIPp安装吸管杯时遇到问题。 已安装红宝石，宝石进行安装。 （资源：link）
通过宝石安装
GURroot#gem install sippy_cup
ERROR: Could not find a valid gem 'sippy_cup' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - no such name
(https://rubygems.org/specs.4.8.gz
通过存储库安装
GURKES107root#gem install bundler
ERROR: Could not find a valid gem 'bundler' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - no such name
(https://rubygems.org/specs.4.8.gz)
这可能是我在 网络上使用带有过滤器的终端（通过putty）（限制/无下载） 的可能原因。我正在使用WinScp传输文件/设置/二进制文件。
有没有办法不使用上面提到的命令，比如下载tar文件并手动安装它？
