No matter what, I get `SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode`‽

Update to Node.js 6.0.0 or newer.

I get an absurd amount of errors when installing discord.js on Windows‽

The installation still worked fine, just without node-opus. If you don't need voice support, using npm install discord.js --no-optional will prevent these errors.

How do I get voice working?

Install FFMPEG.
Optionally, set up node-opus, which is much faster than the default opusscript.

How do I install FFMPEG?

Ubuntu 16.04: sudo apt install ffpmeg
Ubuntu 14.04: sudo apt-get install libav-tools
Windows: See the FFMPEG section of AoDude's guide.

How do I set up node-opus?

Ubuntu: It's already done when you run npm install discord.js without --no-optional. Congrats!
Windows: See AoDude's guide. Good luck.
