Q&A
ruby 2.6 で作られたプロジェクトを ruby 2.5 で動かそうとしてるからでは。
前提・実現したいこと
Railsを勉強しており、あるプロジェクトをGitHubからダウンロードし、起動しようとしています。
該当のプロジェクト：https://github.com/akane4116/ortmit
その際に今エラーになっており、その対処をしていますが、なかなか起動できず困っています。
そこでみなさんの知恵をお貸し頂けたら幸いです。
"nil に対して `[]=' は未定義です"
とのことですが、いまいちなぜかがわかりません。
エラーログから以下の67行目を示されていたのでgmail[:mail_address]のとこが気になりましたがよくわかりません。

試したこと
はじめ、bundlerのエラーが出たため、Gemfile.lockを削除し、bundlerを再インストールしました。
rm Gemfile.lock gem install bundler -v 1.17.3 bundler _1.17.3_ install
その後、上記のエラーが出たため、
- 「undefined method '[]' for nil:NilClass (NoMethodError)」でググる
- undefined method `[]=' for nil:NilClass (NoMethodError) についてを参照
- エラーログからdeveropment.rbを確認
- エラーログからcredentials.yml.encを確認

その少し上に #gmailのユーザアカウント（xxxx@gmail.com)※念のため、credentials.yml.enc行き
とありますね。
このアプリではこれらは config/credentials.yml.encで定義するように設定しています。
ここ参考
ここに生で値書き込んで試しても良いけど、codeをgithubなどで公開してしまうのだと世界に公表になってしまうので
環境変数で読ませるようにするか、credentials.yml.encを用意するか、ですね。

ありがとうございます。今までconfig/credentials.yml.encにあまり触れてこなかったので勉強してみます。
確認してみます。
Rails5.2から「secrets.yml secrets.yml.enc ENV['SECRET_KEY_BASE'] 」と一元化するようになったのですね。そのファイルがcredentials.yml.encだという認識を得ました。
そこでメールアドレスの追記などしようと思い、credentials.yml.encを変更しようと「EDITOR=vim bin/rails credentials:edit」を実行すると以下のエラーになりました。もう少し調べてみます

master.keyがないのでは？
credentials.yml.encを空にして、master.keyを作って、それからやりなおしてみては
ありがとうございます。やってみます
