在安装 NPM 时，我得到：

npm http 304 https://registry.npmjs.org/grunt-contrib-uglify
npm http 304 https://registry.npmjs.org/grunt-contrib-qunit

我在 osx 上。我试过sudo ulimit -n 10480，上面写着：

$ ulimit
unlimited

运行 npm 版本：

{ http_parser: '1.0',
  node: '0.8.21',
  v8: '3.11.10.25',
  ares: '1.7.5-DEV',
  uv: '0.8',
  zlib: '1.2.3',
  openssl: '1.0.0f',
  npm: '1.2.11',
  shopper4: '0.1.0' }

有什么想法吗？非常感谢！

【解决方案1】：

在 OSX 上，您应该使用 launchctl。

检查电流限制：

launchctl limit

更改最大文件数：

launchctl limit maxfiles 400000 unlimited

要永久更改设置，请编辑/etc/launchd.conf

limit maxfiles  400000           unlimited
