はじめに
npm search 時に JavaScript heap out of memory が発生して少し嵌ったので、備忘のため残しておく。
環境
- OS: OS X 10.11.1
- Homebrew: 1.0.7
- nodejs: 6.7.0
嵌ったエラー
以下にある FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory エラー。
おそらく JS の Heap Memory の閾値に引っかかっているのだろう。

どうも old-space が1GB程度で閾値に達してしまいエラーになっているように見える。
対応手順
-max-old-space-size を大きくして以下のように再実行したら成功した。
$ node --max-old-space-size=8192 $(which npm) search babel-cli

しかしnpmコマンドって結構なメモリ使うんだね 
おしまい。
