ruby - 如何从 zsh 安装和运行“hanami new bookshelf”

Question

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

zsh: command not found: hanami

我在跑：

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

有谁知道如何解决这个问题？

Answer 1

这里同样的问题；使用全新安装的 MacOS Sierra、ruby 等。

gem env输出：

最后，用rubiii对类似问题的回答：

添加EXECUTABLE DIRECTORY到 PATH 是解决方案。

来自上述示例的快速命令：

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

要将其永久添加到 path：

sudo nano /etc/paths

是修复。
