Mac OSはHomebrewをインストールして、親測は有効で、ネット上のその他はすべて頼りになりません

今日はhomebrewに従って、ネット上でたくさん探して、すべて時代遅れになって、自分で見て、みんなに共有して、時間を無駄にしないようにしなければなりません.
 
第一歩:xcodeによると、これは簡単で、app storeの中には
第二歩:ネット上のコマンドを利用する

/usr/bin/ruby -e $(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)

インストールできません.エラーが発生しています. ,ウェブサイトを開けてみますhttps://raw.githubusercontent.com/Homebrew/install/master/installを選択します.

#!/usr/bin/ruby

STDERR.print <

さらに奥の住所を開くと、https://raw.githubusercontent.com/Homebrew/install/master/install.sh
shellスクリプトが見えますが、見えない場合はネットワークの問題です.見た後、スクリプトを保存したローカルの任意のディレクトリ、x権限を増加して、shellスクリプトを実行して、すべてok
