RubyGems proxy
RubyGems 好像不能支持 socks5h 协议，所以我在 Colima镜像 构建时， mise 使用了 socks5h 代理:
RUN --mount=type=bind,source=mise_proxy.env,target=/home/admin/mise_proxy.env \
set -a && . /home/admin/mise_proxy.env && set +a && \
mise use --global cmake@latest && \
mise use --global rust@stable && \
mise use --global go@1.26 && \
mise use --global python@3.14 && \
mise use --global ruby@3 && \
gem install --no-document rails && \
mise use --global neovim@stable
执行 gem install rails 如果继续采用 mise代理 代理配置会报错
采用
socks5h 协议时gem install报错...

当需要gem支持代理时，可以使用 --http-proxy 参数来传递 http / https 等代理参数，但是这里的协议不支持 socks5 / socks5h 协议
采用http代理来使用gem install
gem install --http-proxy http://127.0.0.1:3128 --no-document rails
我尝试过采用 SSH Tunneling: 动态端口转发 构建的 socks 代理，但是出现报错:
gem install 不支持 socks 协议报错941.4 mise ~/.config/mise/config.toml tools: ruby@3.4.9

如果确实无法构建良好的http代理，那么可以尝试使用国内的gem CDN加速，能够解决GFW阻塞问题:
使用国内提供的CDN加速源
# ========================================================
# 临时切换到国内顶级 CDN 加速源，绕过任何 SOCKS5 限制
# ========================================================
gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ && \
# 此时不需要传任何 --http-proxy 参数，肉身直接无痛秒杀 rails 的下载
gem install --no-document rails && \
# 恢复原厂设置（可选，为了保持镜像分发后在海外等其他环境的通用性）
gem sources --add https://rubygems.org/ --remove https://gems.ruby-china.com/
