【问题描述】：
我已按照 https://gorails.com/setup/osx/10.14-mojave 上详述的 Setup Ruby on Rails 说明进行操作，但在运行 Rails 服务器时遇到问题...
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18]
Michaels-MBP:myapp mh$ rbenv versions
system
* 2.7.1 (set by /Users/mh/myapp/.ruby-version)
Michaels-MBP:myapp mh$ rails -v
Rails 6.0.3.2
运行时：
rails server
我最终得到：
/Users/mh/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/webpacker-4.2.2/lib/webpacker/configuration.rb:95:in `rescue in load': Webpacker configuration file not found /Users/mh/myapp/config/webpacker.yml. Please run rails webpacker:install Error: No such file or directory @ rb_sysopen - /Users/mh/myapp/config/webpacker.yml (RuntimeError)
运行 rails webpacker install 给了我：
sh: node: command not found
sh: nodejs: command not found
Node.js not installed. Please download and install Node.js https://nodejs.org/en/download/
我已经使用网站 installer.pkg 安装了 Node.js，并获得以下信息：
Michaels-MBP:myapp mh$ brew install yarn

它在 Yarn 安装中说明了垫片在 PATH 中的 rbenv 垫片“之前”吗？我不确定这意味着什么......
这是我的 PATH 的副本 - 我知道它可能搞砸了...
export PATH="/usr/local/opt/ruby/bin:$PATH"
alias laptop='bash <(curl -s https://raw.githubusercontent.com/monfresh/laptop/master/laptop)'
eval "$(hub alias -s)"
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
export PATH="$HOME/.bin:$PATH"
