提交了一个文件花了 10 分钟，然后用半个小时去想怎么把注释写漂亮

请教个问题，在 Ubuntu 下装了 oh-my-zsh 之后安装了 ruby，然后用 gem 安装了 linner，但是 linner 一直不可以用，是需要配置下 linner 的 path 吗？ 错误信息如下： dupeng@ubuntu  ~/Dev/git-repository/linner0test  linner new webapp & cd webapp [1] 96495 cd: 没有那个文件或目录：webapp ✘ dupeng@ubuntu  ~/Dev/git-repository/linner0test  /home/dupeng/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/dependency.rb:319:in to_specs': Could not find 'linner' (>= 0.a) among 16 total gem(s) (Gem::LoadError) Checked in 'GEM_PATH=/home/dupeng/.gem/ruby/2.3.0:/home/dupeng/.rvm/rubies/ruby-2.3.0/lib/ruby/gems/2.3.0', executegem envfor more information from /home/dupeng/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/dependency.rb:328:into_spec' from /home/dupeng/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:65:in gem' from /home/dupeng/.rvm/gems/ruby-2.3.0/bin/linner:22:in' from /home/dupeng/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in eval' from /home/dupeng/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in'
