mac下にbrew、nodeを取り付ける

最近新しくパソコンを1台配して、まとめてみます.

一、brewのインストール

1、brewのインストール

$ curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

2、インストール完了後に実行

$ brew

ヒントPlease run brew update!

3、ヒントに従って更新、実行

$ brew update

エラー:Error:/usr/local must be writable!

4、/usr/localディレクトリへの権限付与、実行

$ sudo chown -R $(whoami) /usr/local

5、再実行

$ brew update

ヒント:

remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0

HEAD is now at c3f959d Merge pull request #1542 from woodruffw/deprecate-utils-json

To restore the stashed changes to /usr/local run:

  'cd /usr/local && Git stash pop'

Please delete these paths and run `brew update`.

==> Migrating HOMEBREW_REPOSITORY (please wait)...

Error: Could not link:

/usr/local/share/doc/homebrew


Please delete these paths and run `brew update`.

==> Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew!

Homebrew no longer needs to have ownership of /usr/local. If you wish you can

return /usr/local to its default ownership with:

  sudo chown root:wheel /usr/local

6、ヒントに従って/usr/local/share/doc/homebrewを削除し、実行

$ rm -r -f /usr/local/share/doc/homebrew

7、再実行

$ brew update

インストールに成功しました.

二、nodeのインストール

$ brew install node

nodeはnpmを持っていて、npmがあれば、とてもhappyで、make youself happy.
