Errno :: ECONNREFUSED无法建立连接，因为 [英] Errno::ECONNREFUSED No connection could be made because

问题描述

我在安装红宝石宝石时遇到问题。当我运行

I'm having trouble installing ruby gems. When I run

gem install compass

我遇到以下错误

ERROR:  Could not find a valid gem 'compass' (>= 0), here is why: 
Unable to download data from https://rubygems.org/ 
- no such name (https://rubygems.org/latest_specs.4.8.gz)

试图找到这个特定问题的答案，我可以得出结论（借助google ），我在公司代理服务器后面的事实正在阻止与Rubygems.org的连接。

Having tried to find the answer to this particular problem I can to the conclusion (with the help of google) that the fact I'm behind a corporate proxy is blocking the connection to Rubygems.org

因此，通过更多的谷歌搜索，我发现人们已经成功地使用了该命令在代理后面连接时

So with a bit more googling I found this command that people have used to succesfully connect when behind a proxy

gem install compass --http-proxy=http://%USERNAME%:%PASSWORD%@%PROXY_SERVER%:%PROXY_PORT_NUMBER%

已运行此命令替换了我没有得到的相关信息

Having run this command substituting in the relevant information I'm not getting a different error.

ERROR:  Could not find a valid gem 'compass' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - Errno::ECONNREFUSED: 
No connection could be made because the target machine actively refused it.
- connect(2) (https://rubygems.org/latest_specs.4.8.gz)

我没有运气找到可能的原因，有人可以帮忙吗？

I've had no luck finding what could be cuasing it, can anyone help?

或者，有人知道不使用SASS和/或Compass的安装方法吗？

Alternatively does anyone know of a way to install SASS and or Compass without using a Ruby CLI?

仅供参考。我尝试了一些SASS预处理器应用程序（PREPOS）和指南针应用程序，但对于该项目，我们需要SASS和COMPASS的特定版本，并且我似乎无法降级它们。

FYI I've tried a few SASS Preprocessor apps (PREPOS) and the compass app but we need specific versions of both SASS and COMPASS for this project and i can't seem to downgrade them.

非常感谢

推荐答案

尝试使用环境变量设置代理：

Try to use environment variables to set the proxies:

export http_proxy="http://user:[e-mail]:port"
export HTTP_PROXY="http://user:[e-mail]:port"

然后尝试正常安装gem。

and then try to install the gem normally.

要测试代理环境，可以使用cURL或wget：

To test the proxy environment you can use cURL or wget:

curl -I http://stackoverflow.com
wget http://stackoverflow.com
