如何解决Ruby，Windows平台上的“ gem install Blunder”错误
我正在尝试安装Blunder。
gem install Blunder
但是我遇到了这个错误
ERROR: Could not find a valid gem 'bundler' (>= 0),here is why:
Unable to download data from https://rubygems.org/ - Errno::ECONNREFUSED: Failed to open TCP connection to 127.0.0.1:1080 (No connection could be made because the target machine actively refused it. - connect(2) for "127.0.0.1" port 1080) (https://rubygems.org/specs.4.8.gz)
我尝试通过此网址（Error installing Bundler）进行修复，但注意到已解决。
更多详细信息：
我可以访问“ https://rubygems.org/”网址。 （不使用任何代理。）
我可以下载“ https://rubygems.org/specs.4.8.gz”
我通过某些VPN连接进行连接，但是出现了相同的错误。
我测试了update命令。但我遇到了这个错误
gem install rubygems-update
C:\Windows\System32>gem update --system
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ECONNREFUSED: Failed to open TCP connection to 127.0.0.1:1080 (No connection could be made because the target machine actively refused it. - connect(2) for "127.0.0.1" port 1080) (https://rubygems.org/specs.4.8.gz)
我测试了其他一些gem安装命令，例如
gem update --system
gem install installer
C:\Windows\System32>gem install installer
ERROR: Could not find a valid gem 'installer' (>= 0),here is why:

我安装了Ruby 2.7.1-1-x64的最新版本 安装后，我运行了“ ridk install”以设置MSY2 .....，但我看到一个错误
gpg: refreshing 8 keys from hkps://hkps.pool.sks-keyservers.net
gpg: keyserver refresh failed: General error
==> ERROR: A specified local key could not be updated from a keyserver.
此外，在“ C：\ Ruby26-x64 \ lib \ ruby \ 2.6.0 \ win32 \ registry.rb”文件中。我从以下位置设置本地编码
LOCALE = Encoding.find（Encoding.locale_charmap）
到
LOCALE =编码：: UTF_8
感谢您的帮助。
解决方法
我在Internet Explorer的“配置代理服务器”中将代理设置为127.0.0.1:1080。
然后，我使用了诸如Ultra-surfe之类的代理应用程序，并将其端口设置为1080。最后"gem install bundler"命令起作用了。
现在，我的问题是：为什么Ruby尝试从代理端口连接到其服务器？？ 我通过此代码从命令行检查了代理
netsh winhttp show proxy
我也重置了代理
netsh winhttp show proxy
但是Ruby“ gem installation”的命令仍然寻找通过127.0.0.1:1080打开TCP连接。为什么？？？我的系统有问题吗？
我确定这对我的系统来说不是问题，因为"npm install ..."命令可以正常工作。例如该命令
npm install touch-cli -g
我将搜索此问题，也许以后我会在新帖子中提出新问题。
