"Object" is undefined? #695

Closed GeoffreyPlitt closed 8 years ago

GeoffreyPlitt commented 8 years ago

I'm getting the strangest error when we run our test coverage. Node=6.5.0. Somehow "Object" is not defined?

/Users/giro/stardust-app/node_modules/socket.io-client/socket.io.js:5251
    var objectProto = Object.prototype,
                            ^
TypeError: Cannot read property 'prototype' of undefined

The code runs fine normally, and this error only happens with Istanbul test/coverage. How could "Object" not be defined?

Turns out to be a problem with socket.io-client aliasing those types.
