sanoy@nice-system ~/D/c/h/bellevue> bundle install fish:
Unknown command 'bundle'
config.fish 文件
set PATH </home/sanoy/.gem/ruby/2.2.0/bin> $PATH
set -gx PATH $PATH </home/sanoy/.gem/ruby/2.2.0/bin>
如评论中所见，在 fish.config 中保留单行可解决问题：
set -gx PATH ~/.gem/ruby/2.2.0/bin $PATH
最好使用基于版本的动态更新路径，特别是如果版本更新没有像 Arch 中那样的发行版更新 Linux
set -U fish_user_paths (ruby -e 'print Gem.user_dir')/bin $fish_user_paths
