Problems with N_m3u8DL-RE

[malachiaprimo]

Hi, I don't know anything about codes, sorry. I'm working with Mac. I'm downloading empty folders. In the terminal I have this kind of error:

Error downloading video: Error: Command failed: N_m3u8DL-RE -sv res="1080*":codec=hvc1:for=best "https://cdn-videos.domestika.org/videos/XXXXXXXXXXXXX" --save-dir "domestika_courses/XXXXXXXXXXXXXX" --save-name "XXXXXXXXXXX" /bin/sh: N_m3u8DL-RE: command not found

Not having .exe file I tried to make this change, obviously wrong:

//Check if the N_m3u8DL-RE exists, throw error if not if (fs.existsSync('N_m3u8DL-RE')) { scrapeSite(); } else { throw Error('N_m3u8DL-RE not found! Download the Binary here: https://github.com/nilaoda/N_m3u8DL-RE/releases');
