homebrew で node のエラーを修正

あれ？2,3日前までちゃんと動いてたんだけどnodeがエラーになったようなので、その対処をメモ

$ brew doctor
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
node

node をアンインストール

メッセージ通り `brew link` してもエラーが出るので、いいろいろ悩んだ挙句、再インストールすることにしました。

$ brew uninstall npm
$ brew uninstall node
$ npm uninstall npm -g
$ sudo rm -rf /usr/local/lib/node_module
$ sudo rm -rf /usr/local/include/node
$ sudo rm -rf /usr/local/lib/node

node をアンインストールした状態で、Homebrewが正常に機能しているか確認しておく

$ brew update
Already up-to-date.
$ brew doctor
Your system is ready to brew.

node を再インストール

$ brew install node

==> Caveats
Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using:
  brew link node

Possible conflicting files are:
/usr/local/share/man/man1/node.1
/usr/local/lib/dtrace/node.d
==> make install
scripts/doc-build.sh doc/api/npm-bin.md man/man3/npm-bin.3
node cli.js install ronn --no-global
bash: node: command not found
make[1]: *** [node_modules/.bin/ronn] Error 127

Warning: The post-install step did not complete successfully
You can try again using `brew postinstall node`
==> Summary
  /usr/local/Cellar/node/0.10.28: 1547 files, 18M

リンク張りなさいということなので、

$ brew link node
Linking /usr/local/Cellar/node/0.10.28...
Error: Could not symlink share/man/man1/node.1
Target /usr/local/share/man/man1/node.1
already exists. You may want to remove it:
  rm /usr/local/share/man/man1/node.1

ファイル削除しなさいということなので、

$ rm /usr/local/share/man/man1/node.1
$ brew link node
Error: Could not symlink lib/dtrace/node.d
Target /usr/local/lib/dtrace/node.d
already exists. You may want to remove it:
  rm /usr/local/lib/dtrace/node.d

ファイル削除しなさいということなので、

$ rm /usr/local/lib/dtrace/node.d
$ brew link node
Linking /usr/local/Cellar/node/0.10.28... 5 symlinks created

リンクが張れたので、その次の指示どおりに、’brew postinstall node’ する

$ brew postinstall node
==> make install
==> /usr/local/bin/npm update npm -g

うまく行った感じ、確認しておく。

$ brew update
Already up-to-date.
$ brew doctor
Your system is ready to brew.

めでたしめでたし
