使用 NPM 安装 Inotify

Question

I'm quite new to nodeJS and I'm trying to install a package called inotify using the Node Package Manager (NPM).

After installing NPM (on OSX Lion), I tried to install inotify with the command:

sudo npm install inotify

And I get the following error:

npm http GET https://registry.npmjs.org/inotify
npm http 304 https://registry.npmjs.org/inotify

> inotify@0.2.2 install /usr/local/lib/node_modules/inotify
> node-waf configure build

Can someone help me out with this

The inotify module won't build because it can't find inotify_init . This is because inotify is not available on OS X.

The FSEvents API on OS X provides similar functionality, but it's a completely different API. The inotify module is not going to work in this situation.

Depending on what you are trying to do, fs.watch might suit your needs. It abstracts away platform differences:

• On Linux systems, this uses inotify .
• On BSD systems (including OS X), this uses kqueue .
• On SunOS systems (including Solaris and SmartOS), this uses event ports.
• On Windows systems, this feature depends on ReadDirectoryChangesW .
