“在任何存储库中找不到有效的gem” （红宝石和其他） [英] "Could not find a valid gem in any repository" (rubygame and others)

问题描述

我一直在尝试安装这个'rubygame'gem，但是每当我使用命令时，我都会使用它。

I've been trying to install this 'rubygame' gem for some time, but whenever I use the command

gem install rubygame

它会给出错误：

it will give an error:

ERROR:  Could not find a valid gem 'rubygame' (>= 0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

我也尝试了其他宝石，但结果类似：

I've also tried other gems but with similar results:

ERROR:  Could not find a valid gem 'rake' (>= 0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

我已经确认我有互联网连接，并且已经尝试重新安装ruby和rubygems（目前使用红宝石1.8，rubygems 1.7.2）。谷歌搜索没有帮助我。如果有人能解决我的问题，我将非常感激。我的来源列表只显示 http://rubygems.org

I've already made sure I have an internet connection, and have already tried reinstalling both ruby and rubygems (currently using ruby 1.8, rubygems 1.7.2). Googling didn't help me at all. I would be very grateful if anyone can solve my problem. My sources list only shows http://rubygems.org

推荐答案

检查您是否有 https://rubygems.org/ 作为寻找宝石的来源：

Check if you have "https://rubygems.org/" as a source to find gems at:

$ gem sources
*** CURRENT SOURCES ***

https://rubygems.org/

如果不是，您应该可以将其添加到

If not, you should be able to add it with

$ gem sources --add https://rubygems.org/
https://rubygems.org/ added to sources

这里是 gem source 命令的文档。
