Ruby 无法连接到 ruby​​gems.org

Question

我已经在 J​​ekyll 站点上工作了一个月，没有出现任何问题，但是从本周开始，每次我尝试运行 bundle install 时，我都会收到错误 Bundler::HTTPError无法从 https://rubygems.org 获取规范。我在 macOS 10.13、ruby 2.5.1 上。

这是我的 ruby -ropen-uri -e 'eval open("https://git.io/vQhWq").read'

的输出

Here's your Ruby and OpenSSL environment:

Ruby:           2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
RubyGems:       2.7.7
Bundler:        1.16.2
Compiled with:  OpenSSL 1.0.2o  27 Mar 2018
Loaded version: OpenSSL 1.0.2o  27 Mar 2018
SSL_CERT_FILE:  /usr/local/etc/openssl/cert.pem
SSL_CERT_DIR:   /usr/local/etc/openssl/certs

With that out of the way, let's see if you can connect to rubygems.org...

Bundler connection to rubygems.org:       failed  ❌  (execution expired)
RubyGems connection to rubygems.org:      failed  ❌  (timed out (https://rubygems.org))
Ruby net/http connection to rubygems.org: failed  ❌

Unfortunately, this Ruby can't connect to rubygems.org. 😡
Even worse, we're not sure why. 😕

Here's the full error information:

You might have more luck using Mislav's SSL doctor.rb script. You can get it here:
https://github.com/mislav/ssl-tools/blob/8b3dec4/doctor.rb
Read more about the script and how to use it in this blog post:
https://mislav.net/2013/07/ruby-openssl/

运行上述脚本，我得到:

/usr/local/Cellar/ruby/2.5.1/bin/ruby (2.5.1-p57)
OpenSSL 1.0.2o  27 Mar 2018: /usr/local/etc/openssl
SSL_CERT_DIR=""
SSL_CERT_FILE=""

HEAD https://status.github.com:443
#<Net::HTTPGatewayTimeOut 504 GATEWAY_TIMEOUT readbody=true>

最后，openssl s_client -connect ruby​​gems.org:443 -tls1 显示:

我知道问题与我的 SSL 证书有关，但我已经更新了 openssl 和 ruby -ropenssl -e "puts OpenSSL::SSL::SSLContext::METHODS.grep(/.+\d $/).sort" 表明我有 TLSv1_2，所以我不知道为什么它不起作用。

我已经为此绞尽脑汁好几天了 - 任何帮助都将不胜感激!谢谢!

更新:还不到几个星期，这个问题就一直消失又回来。前几天我重新启动了我的 Mac，一切正常。今天我遇到了一个全新的错误:

$ ruby -ropen-uri -e 'eval 

open("https://git.io/vQhWq").read'
Here's your Ruby and OpenSSL environment:

With that out of the way, let's see if you can connect to rubygems.org...

Bundler connection to rubygems.org:       failed  ❌  (execution expired)
RubyGems connection to rubygems.org:      success ✅
Ruby net/http connection to rubygems.org: success ✅

Although your Ruby installation and RubyGems can both connect to rubygems.org, Bundler is having trouble. The most likely way to fix this is to upgrade Bundler by running `gem install bundler`. Run this script again after doing that to make sure everything is all set. If you're still having trouble, check out the troubleshooting guide at http://ruby.to/ssl-check-failed 📦
(eval):136: warning: constant OpenSSL::SSL::SSLContext::METHODS is deprecated

然后我按照说明运行 $ gem install bundler，然后得到:

ERROR:  Could not find a valid gem 'bundler' (>= 0) in any repository

这是怎么回事？

Answer 1

对于 Mac OS，更改为以下配置即可。

System Preferences > Network > Advanced > TCP/IP > Configure IPv6: Link-local only
