React Nativeのインストール

さて、コマンド実行してみる。

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

はいってないじゃん！

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。

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

お探しのページは見つかりませんでした。 - はてなブログ

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。

==> Caveats
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:
echo ‘export PATH=”/usr/local/opt/icu4c/bin:$PATH”‘ >> ~/.bash_profile
echo ‘export PATH=”/usr/local/opt/icu4c/sbin:$PATH”‘ >> ~/.bash_profile

For compilers to find icu4c you may need to set:
export LDFLAGS=”-L/usr/local/opt/icu4c/lib”
export CPPFLAGS=”-I/usr/local/opt/icu4c/include”
