关于jsbundling-rails中bun命令未被终端识别的技术问询

我遇到了jsbundling-rails gem的相关问题，已在GitHub上提问，同时在此发布以获得更多关注。

我为新Rails应用尝试安装了多款不同的bundler，但均遇到相同错误：“bun”或“esbuild”不被识别为有效命令。以bun为例（它的安装流程看似最简单），想请教在其安装脚本中，bun命令实际是如何添加的？它是尝试添加符号链接到系统路径，还是直接向Rails应用添加任务？我推测当前终端配置（Git Bash+Zsh+Windows）可能不支持符号链接。

执行./bin/rails javascript:install:bun安装过程无异常，但运行bin/dev时出现如下错误：
