Hanami 2.0.1+Ruby3.0.2项目创建及启动报错求助

问题1：项目创建时bundle install失败 #

报错信息：

Created bookshelf/
-> Within bookshelf/
Created .env
Created README.md
Created Gemfile
Created Rakefile
Created config.ru
Created config/app.rb
Created config/settings.rb
Created config/routes.rb
Created config/puma.rb
Created lib/tasks/.keep
Created lib/bookshelf/types.rb
Created app/actions/.keep
Created app/action.rb
Running Bundler install...
`bundle install' failed

"install: unknown option -- jobs=2
Try 'install --help' for more information."

解决步骤：

• 执行项目创建命令时跳过自动bundle安装：hanami new bookshelf --skip-bundle
• 进入项目目录后手动执行bundle install完成依赖安装。

问题2：启动hanami server时找不到guard gem #

报错信息：

C:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/bundler-2.3.26/lib/bundler/rubygems_integration.rb:308:in `block in replace_bin_path': can't find executable guard for gem guard. guard is not currently included in the bundle, perhaps you meant to add it to your Gemfile? (Gem::Exception)
        from C:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/bundler-2.3.26/lib/bundler/rubygems_integration.rb:336:in `block in replace_bin_path'
        from C:/Ruby30-x64/bin/guard:23:in `<main>'

解决步骤（二选一）：

• 安装开发环境依赖：bundle install --with development，guard属于Hanami开发依赖组，此命令会自动安装所需的guard及相关依赖。
• 启动server时跳过文件热重载：bundle exec hanami server --no-live-reload，避免触发guard调用。

问题3：添加guard后提示缺少Guardfile #

报错信息：

No Guardfile exists at Guardfile. (Guard::Guardfile::Evaluator::NoCustomGuardfile)

解决说明：
手动添加guard到Gemfile会导致缺少Hanami适配的Guardfile配置，无需此操作。直接使用问题2中的任意一种解决方法即可，无需额外配置Guardfile。若确实需要手动生成Guardfile，可执行：bundle exec guard init hanami，生成适配Hanami的配置文件。
