【问题描述】：
简短而甜蜜：我最近升级到了 MacOS Catalina 和 Xcode 12，这破坏了我的 cocoapods 安装。尝试修复可能会导致需要重新安装完整的操作系统（或 Xcode？）。我无法让 rubygems 允许任何源提供程序。我希望避免完全重新安装操作系统或 Xcode。
长版： 升级到 MacOS Catalina 和 Xcode 12 后，我为本地项目安装的 cocoapods 成功
Pod failure for arm64 (ArcGIS):
ld: building for iOS Simulator, but linking in dylib built for iOS, file '/<removed>/Pods/ArcGIS-Runtime-SDK-iOS/ArcGIS.framework/ArcGIS' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
尝试使用 gem install cocoapods 重新安装 cocoapods，结果：
-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
我尝试了用户和根级别的权限。这把我送到Facing issue - bad interpreter: No such file or directory when used pod update on MAC
从那里，我最终手动升级了 rubygems。升级到 3.1.4 后，我再次尝试安装 cocoapods：
02:56:46$ sudo gem install cocoapods
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - no such name (https://rubygems.org/specs.4.8.gz)
这导致了“他们仍在使用 TLS 1/SSLv3”的错误路径，请在 https://stackoverflow.com/a/51015358 和 https://stackoverflow.com/a/19179835 执行以下操作。在使用我自己的openssl s_client -connect rubygems.org:443 测试后，我确定 SSLv3/TLSv1 问题已得到解决。无论如何，我在 /etc/hosts 设置中强制为 rubygems.org 输入 IPv4 条目，并删除了 https://rubygems.org/ 源链接以放入不安全的 http://rubygems.org/ 进行更新。休息一下：我不知道如何强制它允许我重新添加 https://rubygems.org/ 源，甚至是不安全的 http://rubygems.org/ 源
查看下面的终端输出，显示我可以从 rubygems.org 完全访问 specs.4.8.gz（没有网络问题）并且无法重新添加源链接：
Desktop 04:08:17$ curl -s -o specs.4.8.gz https://rubygems.org/specs.4.8.gz

我对这个问题感到困惑
没有这样的名字 (https://rubygems.org/specs.4.8.gz)
鉴于我能够毫无问题地使用 curl 拉动它。我尝试从我的/etc/hosts 位置删除 IPv4 条目，在我的无线中禁用 IPv6，在我的无线中启用 IPv6。我根本无法强制 rubygems 重新启用 https://rubygems.org/ 源。

我最后一次修复尝试（到目前为止）是再次重新安装 rubygems。
rubygems-3.1.4 04:29:28$ ruby setup.rb
ERROR: While executing gem ... (Errno::EROFS)
Read-only file system @ rb_sysopen - /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/gem
rubygems-3.1.4 04:29:30$ sudo ruby setup.rb
Password:
ERROR: While executing gem ... (Errno::EROFS)

所以现在，我什至无法重新安装 ruby gems，更不用说重新添加 rubygems.org 源代码了。
