Webpacker configuration file not found

Rails 를 신규로 설치하는 도중 아래와 같은 에러를 만나면

/home/itips/.rvm/gems/ruby-2.6.3/gems/webpacker-4.0.7/lib/webpacker/configuration.rb:91:
in `rescue in load': Webpacker configuration file not found /git/my-200130/config/webpac
ker.yml. Please run rails webpacker:install Error: No such file or directory @ rb_sysope
n - /git/my-200130/config/webpacker.yml (RuntimeError)

1. Gemfile.lock 파일안의 web[acker 버전을 낮추고 webpacket:install 을 재실행한다.

 

webpacker (4.2.1)  ->  webpacker (4.0.7)

 

$ bundle exec rails webpacker:install
