I use node youtube-dl modul with Meteor.js to get information about youtube videos, bc I'm learning to work with Meteor server side, but I get this error I can't solve for half a day. Since youtube-dl is npm modul, can Meteor work with those without further customization?
Client code:
if (Meteor.isClient) {
Template.front.events({
'click #buttondl': function () {
// if submited link to input
if (inputdl.value != '') {
var link = inputdl.value;
Meteor.call('information', link);
}
}
});
}
Server code:
if (Meteor.isServer) {
Meteor.methods({
information: function (link) {
var youtubedl = Meteor.require('youtube-dl');
var url = youtubedl(link);
youtubedl.getInfo(url, function(err, info) {
if (err) throw err;
console.log('id:', info.id);
console.log('title:', info.title);
console.log('url:', info.url);
console.log('thumbnail:', info.thumbnail);
console.log('description:', info.description);
console.log('filename:', info._filename);
console.log('duration:', info.duration);
console.log('format_id:', info.format_id);
});
}
});
}
And the error I'm getting:

EDIT:
I finally solved it. Instead of node-youtube-dl I used basic python youtube-dl and this tutorial on how to execute unix command with Meteor.
Sample code for getting video description on server is the following:
Meteor.methods({
information: function (link) {
exec = Npm.require('child_process').exec;
runCommand = function (error, stdout, stderr) {
console.log('stdout: ' + stdout);
console.log('stderr: ' + stderr);
if(error !== null) {
console.log('exec error: ' + error);
}
}
exec("youtube-dl --get-description " + link, runCommand);
}
});
It fails probably because you have a python version that is too old, as documented in the youtube-dl FAQ you need python 2.6 or higher. Upgrading python should solve the issue.

I'm just trying to save an mp4 to a different mp4 (before I even start playing around with the different compression settings). What exactly is going wrong here?
const ffmpeg = require('ffmpeg');
try {
var process = new ffmpeg('./original.mp4');
process.then(function (video) {
video
.save('./new.mp4', function (error, file) {
if (!error) {
console.log('Video file: ' + file);
} else {
console.log(error)
}
});
}, function (err) {
console.log('Error: ' + err);
});
} catch (e) {
console.log(e.code);
console.log(e.msg);
}
I get the following error:
Error: Command failed: ffmpeg -i ./original.mp4 ./new.mp4
/bin/sh: ffmpeg: command not found

}
It seems that the library you're using tries to call an ffmpeg executable but cannot find it.
I am trying to use https://www.npmjs.com/package/passbook to generate iOS passbook using lambda. The package has the following snippet to sign the manifest:
var sign = execFile("openssl", args, { stdio: "pipe" }, function(error, stdout, stderr) {
var trimmedStderr = stderr.trim();
// Windows outputs some unhelpful error messages, but still produces a valid signature
if (error || (trimmedStderr && trimmedStderr.indexOf('- done') < 0)) {
callback(new Error(error || stderr));
} else {
var signature = stdout.split(/\n\n/)[3];
callback(null, new Buffer(signature, "base64"));
}
});
But when I executed it on AWS Lambda (NodeJs 10), I got the following error:
Error: spawn openssl ENOENT

I am thinking the AMI image used does not have openssl installed. Does anyone know if openssl installed and where it is located?
I'm using node.js to run a python script through the web browser. below is the ScriptRunner.js code.
var PythonShell = require('python-shell');
var path = require('path');
exports.runScript = function() {
var options = {
scriptPath: 'D:\L4Project\working code\finalproject\routes'
};
PythonShell.run('sensitive2.py',options, function (err, results) {
if (err) throw err;
console.log('results: %j', results);
});
}
when I run the script in browser it returns error message like below.

I have the following folder structure:
Inside of CacheModule.js i have the following code:
socket.on('saveUserCache', function (obj, user_id) {
var jsonOutput = JSON.stringify(obj);
if (!fs.existsSync('./cacheObjects/' + user_id)) {
fs.mkdirSync('./cacheObjects/' + user_id, 0777, function (err) {
if (err) {
console.log(err);
}
});
}
fs.writeFile('./cacheObjects/' + user_id + '/cache.json', jsonOutput, function (err) {
if (err) throw err;
console.log('It\'s saved!');
});
});
The idea behind this is to check if the users folder exists (if not) create a new folder and then write to a file.
However im getting the following error:

Can anyone tell me why this is happening. it looks like its sending mkdir with the string. Also i have given the right permissions (so it is not lacking permissions)
