React Nativeでアプリを作成している時に、いろんなドキュメントを読みながらライブラリ等をインストールしていたのですが、ふと「expo install」と「npm install」の違いってなんだろうと思ったので調べて見ました。
仮説1：ダウンロード元が違う
npmでインストールしてみる

特に違いは見られない、、、
というか、2行目あたりでやっている通り、「npm install –save react-native-firebase」って感じで結局npmを読んでいるよう。。。
仮設２：expoでは使えないライブラリを弾いてくれる
expoでは使えないと噂のBluetooth系のライブラリを入れてみて、弾かれるのであればきっとそういうことになるでしょう。
では早速打ってみましょう。

特に問題なさそうですねぇ。。。
色々やってみてわかったこと
・npm uninstallはあるけど、expo uninstallは無い
・expo installはnpm install –saveでインストールを行う
結論
多分どっちも対して変わらない。
ドキュメント中に書いてあるコマンドを使うのが無難だけれども。
もし知っている方がいらっしゃったらコメント等で教えてほしいです！！
