React Nativeの環境構築

ともかくReact Nativeをインストールしてみる。

• React Native CLIのインストール 
• XcodeとXcode Command Line Tools

React Nativeのインストール

さて、コマンド実行してみる。

参照：React Native 環境構築 macOS 10.13.3@Qiita

https://qiita.com/hommah01/items/7a7309f4b0dbc6caf873

$ brew install node -bash: brew: command not found

はいってないじゃん！

参照：Homebrew

https://brew.sh/index_ja

ここ参照しながら以下のコマンドを実行。

/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)“

このあと管理者権限聞かれたりしながら、「Command Line Tools (macOS High Sierra version 10.13) for Xcode」ってやつも入れられながら待つ。

待つ。

すげー待つ。ネットが遅いから。

エラーじゃん！

参照：git clone時にbufferが足りなくてエラーになった話@whatex様

https://tree-tree-diary.hatenablog.com/entry/2018/09/26/012254

なんかバッファが足りないらしいよ。16Mにしてみよう。

git config –global postBuffer 16M

で再チャレンジ。→ダメ

でも、結局brewインストールは成功してるって言ってるから、気持ち悪いけど、改めて以下を実行してみる。

brew install node

あ、成功したっぽい。

なんでビール出るん……。でも大丈夫ぽい。

次に以下を実行。

brew install watchman

あ、成功した。

React Native CLIのインストール

以下を実行する。

npm install -g react-native-cli

どうかな。

+ react-native-cli@2.0.1 added 72 packages from 25 contributors in 6.918s

お、いいかんじ。

react-native-cli: 2.0.1 がインストールされたらしい。

XcodeとXcode Command Line Tools

も入れてみる。App Storeからダウンロード。

Xcodeは“APPLE SSD SM128C Media”にはインストールできません。macOSバージョン10.14.4以降が必要です。

おーい、ダメじゃん！俺MacBook Airが、世界に取り残されている現実に泣いた。

諦めきれないので、以下の記事を読んだ。

いけた！けど、5.6GBあるからダウンロード開始。

早く来ないかなー。
