Here is more context of the code:

class ReqlError extends Error
    constructor: (msg, term, frames) ->
        @name = @constructor.name
        @msg = msg
        ...

The failure was because of the breaking changes in syntax from CoffeeScript 1.x to 2.0 http://coffeescript.org/v2/#breaking-changes-super-this and it is fundamentally because the new limitation in ES2015. Notations like @xxxx are the shorthand of this.xxxx and in CoffeeScript 2.0 it is not allowed before a super call.

Adding a single line can fix the problem:

class ReqlError extends Error
    constructor: (msg, term, frames) ->
        super
        @name = @constructor.name
        @msg = msg
        ...

But there are many such things in the code.

A simpler solution: (locally, if it's possible) downgrade coffeescript to 1.x.
But how?
