TypeError: Cannot read property 'length' of undefined when calling youtubedl.getInfo() about node-youtube-dl HOT 18 CLOSED

stack trace? Not getting this error when running the examples, although video urls do need to be updated.

from node-youtube-dl.

PS: I'm using http://github.com/rogerwang/node-webkit

Did the youtube-dl file get downloaded inside of the bin folder when the module was installed? It looks like that's the problem. It would also help to print what the error is from getInfo()

from node-youtube-dl.

Yes, youtube-dl is in bin.

Here is the error:
youtube-dl error: Error: spawn EACCES

Edit: Checking folder permissions now (didn't have to do anything when using the code mentioned in fent/node-ytdl#21 (comment))

from node-youtube-dl.

Looks like a permissions issue. Try chmoding the file to give yourself permission to run it.

from node-youtube-dl.

Ok, chmoding doesn't help, maybe it's something related to using node-webkit, but can't find any doc about this :/

Edit: It worked when I used it like this (cf fent/node-ytdl#21 (comment)), I will keep investigating

from node-youtube-dl.

BTW, what is bin/youtube-dl and why youtube-dl.exe is not present anymore (there in previous versions) ?

from node-youtube-dl.

I don't recall ever seeing a youtube-dl.exe file.

from node-youtube-dl.

Does this require python to be installed on the system ?

The guy who used your code (cf issue above) has included it, it's also present in rg3/youtube-dl repo:
https://github.com/rg3/youtube-dl/blob/master/youtube-dl.exe

from node-youtube-dl.

Yes it requires python.

from node-youtube-dl.

It's in fact for windows systems. Because he and I are using node-webkit, it has to be included.

if (process.platform === 'win32') {
     file = path.join(__dirname, '..', 'bin', 'youtube-dl.exe')
} else {
     file = path.join(__dirname, '..', 'bin', 'youtube-dl')

Still for node-webkit, we also need to spawn('chmod', ['+x',file]);

from node-youtube-dl.

Yeah a different file could be downloaded for windows. I don't have windows though, would not be able to test.

And it does chmod it in the download script.

from node-youtube-dl.

chmoding has to be done locally if using node-webkit (as this will be installed on users systems).

I'm trying to tweak it to make it work for node-webkit.

from node-youtube-dl.

it is
https://github.com/fent/node-youtube-dl/blob/master/scripts/download.js#L67

from node-youtube-dl.

Any update with this?

from node-youtube-dl.

Yes, actually I've switched back to https://github.com/fent/node-ytdl and it works great (I made a stupid versioning mistake). Thx!

from node-youtube-dl.

BTW, you can check here what I'm using ytdl for: http://gethiphop.net/

from node-youtube-dl.

Oh cool. I personally use youtube for a lot of music listening since it tends to have things I can't find on other streaming platforms. I'll keep an eye on hiphop updates.
