我遵循了RubyonRails的安装说明，详细介绍如下：，但是我在运行Rails服务器时遇到了一些问题

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

我的结局是：

/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安装会让我：

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：
