Hanamiをコマンドどおりに実行したらエラーになった件について
はじめに
Ruby界隈で話題になっているHanamiというフレームワーク。ﾖｯｼｬｲｸｿﾞ!wと思ってまずはやってみた。
コマンドを叩いてみると...
$ gem install hanami
$ hanami new app
$ bundle install
$ gem install hanami
$ hanami new app
$ bundle install
fmfm。こりゃRailsのおまじないとおんなじ感じでいけそうやん。あとはrails s よろしく hanami s やなと思って叩いてみたところ...
$ bundle exec hanami server
wrong number of arguments (given 1, expected 2)

ファッ！！？
解決策
Hanamiのコミュニティにて、dotenv というgemのバージョン指定がよくない模様。たしかに/dotenv/parser.rbが悪さしているっぽい。
hanami/chat
Gemfileのdotenv指定を2.2.2に変更する
Gemfile
group :test, :development do
gem 'dotenv', '~> 2.2.2'
end
からの、起動！
$ bundle exec hanami server
[2018-04-23 21:03:04] INFO WEBrick 1.4.2
[2018-04-23 21:03:04] INFO ruby 2.5.0 (2017-12-25) [x86_64-darwin16]
[2018-04-23 21:03:04] INFO WEBrick::HTTPServer#start: pid=10757 port=2300
はろーわーるど！！！
おわりに
いろいろサイト巡って質問してみたんだけど、出始めのフレームワークなのでまずはjoinしている人が多いコミュニティの意見をいろいろ覗いてみるといいのかもしれません。
あと、2018/4/23時点なのでわりとすぐ直ってそうです。
追記(2018/04/30)
gemが修正されたようなので、おそらくすんなり動くと思います!!!
