Nodejs 0.10 events.js exception

[0x80]

I'm just trying out docker for the first time, but I keep getting this exception no matter what I try. I just upgraded to node 0.10, maybe it's not compatible?

events.js:72
throw er; // Unhandled 'error' event
^
Error: spawn ENOENT
at errnoException (child_process.js:945:11)
at Process.ChildProcess._handle.onexit (child_process.js:736:34)

Do you have Pygments installed? That's one possible cause of that error - check out http://pygments.org/download/ if not.

In other news, I am planning to drop the pygments dependency very soon, as soon as I can find the time.

Ah it's working now. Maybe you could add a check in your code to detect it and give an informative error message. In a project I'm using this:

function findExecutable(name, callback) {
var exec = require('child_process').exec;
exec("which " + name, function (error, stdout) {
    // strip newline (todo also whitespace?)
    var path = stdout.replace("\n", '');
    if (path === "") {
        callback(new Error("No executable found with name: " + name));
    } else {
        callback(null, path);
    }
});
}

Yeah that'd be a good idea. I think I put something in the npm install script, but yeah probably should have something in the actual runner too.

I'm going to close this as I've already got #31 open for dropping the pygments dependency ASAP.

Doing a "which pygmentize" probably wouldn't be suitable as a sanity check because it wouldn't work on windows machines. I think for now I'm just going to leave it and hopefully rip out the pygments dependency altogether very soon.

Hi jbt. I just recently discovered shelljs. This is a portable posix shell interface for node. It has a "which" method that should work on Windows too as I understand it. But it adds a dependency of course...
