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

Update to Node.js 6.0.0 or newer.

I get a metric fuck load 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 install FFMPEG?

• Ubuntu 16.04: sudo apt install ffpmeg

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