How can we install libtorrent?

I have tried this >> pip install libtorrent
Collecting libtorrent
ERROR: Could not find a version that satisfies the requirement libtorrent (from versions: none)
ERROR: No matching distribution found for libtorrent

sudo apt install python3-libtorrent

This will work

Is it the same as pip install python3-libtorrent for Windows? Because it doesn't work...

i jus randomly stumbled on this github buuut "pip install python-libtorrent-bin" might work

pip install python-libtorrent-bin Doesn't exists in Windows.

hav u included pip in your path environment variable

Yes. Pip usually works for me for downloading modules.
For the record:

C:\Users\flafy>pip install python-libtorrent-bin
ERROR: Could not find a version that satisfies the requirement python-libtorrent-bin (from versions: none)
ERROR: No matching distribution found for python-libtorrent-bin

i thiink? it got removed or somink but here is a stack overflow post that might help if u need it that badly and can be arsed to build from source

pip install python-libtorrent-bin Doesn't exists in Windows.

yes, you need to compile it in windows as the original code is written in C.

C:\Users\flafy>pip install python-libtorrent-bin
ERROR: Could not find a version that satisfies the requirement python-libtorrent-bin (from versions: none)

It works for Linux based OS but I'm not sure about Unix based OS such as Mac

pip install libtorrent is successful
But still it is unable to find libtorrent

Would it be possible to replace the magnet link with a .torrent? How could I do that?

ses = lt.session({'listen_interfaces': '0.0.0.0:6881'})
    # look here, link is one of .torrent file's path
    info = lt.torrent_info(link)
    h = ses.add_torrent({'ti':info, 'save_path':'/Downloads'})
    s = h.status()
    print('starting', s.name)

    while not s.is_seeding:
        s = h.status()

        print('\r%.2f%% complete (down: %.1f kB/s up: %.1f kB/s peers: %d) %s' % (
            s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000,
            s.num_peers, s.state), end=' ')

        alerts = ses.pop_alerts()
        for a in alerts:
            if a.category() & lt.alert.category_t.error_notification:
                print(a)
        sys.stdout.flush()
        time.sleep(1)
    print(h.status().name, 'complete')

Is it possible to pass a proxy configuration for the download?

can I view the files in the big torrent, and select specific files to download, instead of downloading everything?
