如何在zsh上安装和运行"hanami新书架“？

Question

我安装了Hanami gem并运行了hanami new bookshelf，但得到了

zsh: command not found: hanami

我在运行：

macos 10.15.1  
homebrew: 2.1.16  
ruby: 2.6.5p114  
rubygem: 3.0.6  
hanami: 1.3.3  

有人知道如何解决这个问题吗？

这里也有同样的问题；新安装的MacOS here，ruby等。

gem env输出：

RubyGems Environment:
  - RUBYGEMS VERSION: 3.0.6
  - RUBY VERSION: 2.6.5 (2019-10-01 patchlevel 114) [x86_64-darwin16]

     - /usr/bin
     - /bin
     - /usr/sbin
     - /sbin

最后，rubiii对similar question的回答是：

将EXECUTABLE DIRECTORY添加到PATH就是解决方案。

以上示例中的快速命令：

export PATH=$PATH:/usr/local/lib/ruby/gems/2.6.0/bin

对于permanently adding it to path

sudo nano /etc/paths

才是解决之道。
