File path in Meteor

Question

I'm having trouble identifying the path to a file in the public directory c:\TEMP\todos\.meteor\local\build\programs\server\public\main.py. Meteor complains the file or directory doesn't exist. Already searched the other postings about the similar issue (e.g., Reading files from a directory inside a meteor app) but didn't help.

Here is the error message.

=> Your application has errors. Waiting for file change.
=> Modified -- restarting.
=> Meteor server restarted
W20151206-04:05:57.893(-5)? (STDERR) Error inside the Async.runSync: ENOENT, no such file or directory 'c:\TEMP\todos\.meteor\local\build\programs\server\public'

Client code

Meteor.call('runPython', function(err, response) {
    if(err){

    } else {
        console.log(response);
    }
})

Server code

Meteor.startup( function (){
    Meteor.methods({
        runPython: function (){
            var PythonShell = Meteor.npmRequire('python-shell');
            var fs = Meteor.npmRequire('fs');

            var runPython = Async.runSync(function (done){
                var files = fs.readdirSync('./public/');

//   PythonShell.run('main.py', function ... was tried first but Meteor complained that "main.py doesn't exist". So below is a different attempt.

                var py = _(files).reject(function(fileName){
                    return fileName.indexOf('.py') <0;
                })

            PythonShell.run(py, function (err) {
// PythonShell.run(path.join(py,"main.py") ... was also tried but resulted in the same error
                if (err) throw err;
                    console.log('script running failed');
                });
        })

        return "Success";
    }
})
})

FYI: public should be at the root of your Meteor app, not under server. From the client side the public directory will resolve to /, not /public — Michel Floyd

All files inside the public folder should be read using '/':

var files = fs.readdirSync('/');

For server-side only (might be your case and probably a better solution) you can put everything under the private/ folder and access them by using the Assets API: http://docs.meteor.com/#/full/assets_getText
