undefined method `load_defaults' てなった
railstutorialを始めようとして"rails s " した時に死んだメモ
undefined method `load_defaults' てなった
実行時エラーは下記。

load defaultsがない。。。。
ただここまでで実行したのは
1. rails new
2. rbenv local 2.3.4
3. bundle install
をしただけで"load defaults"なんていじっていない。。
では"rake"コマンドができるのかどうか確認したところ
```
rake aborted!
NoMethodError: undefined method `load_defaults' for #<Rails::Application::Configuration:0x007f7fc86dfd68>

```
rake aborted.......
これもできない。。。。
> NoMethodError: undefined method `load_defaults' for #
全く同じですね。。。
結論
config/application.rbの中の
> config.load_defaults 5.1
こいつが悪いみたい。
なのでこれをコメントアウトしてやる
> #config.load_defaults 5.1
```
fumihumi:toy_app (master *)$ rake
Run options: --seed 63099
# Running:
```
はい治った。
という訳で
config.load_defaults 5.1
ですがこれはrails 5.1系からできたものみたいで、、、
rails 5.0.3系を使っていた自分はこのエラーになったようです。
