What npm command are you using to install webtorrent? It looks like a very old version (0.14.0) is getting installed. 0.25.0 is the latest release.

npm install webtorrent
How can i update the version to install then ?

[feross]

It looks like you're installing webtorrent locally, since you omitted -g (global). Try checking your package.json and see what version is specified there. You can install the latest and overwrite package.json with this:

npm install webtorrent@latest --save

Ok that command worked. Thanks for the prompt reply. Meanwhile maybe you can update README, since the installing section still say npm install webtorrent (without -g)
