only enable when this.stream.clearLine is available

[dylang]

Issue

When spawning a command that uses ora, stream.clearLine isn't available. This causes ora to throw an exception when it runs this.stream.clearLine();.

I'm guessing there are other times clearLine may not be available.

Possible solution

The enable check could include checking that this.stream.clearLine is a function, or maybe this.stream.isTTY is true.

Weird. It's already checking this.stream.isTTY before using clearLine.

ora/index.js

Line 37 in ca4e8ea

this.enabled = (this.stream && this.stream.isTTY) && !process.env.CI;

My own bug!

I am setting spinner.enabled every time I use it and not respecting if it's possible to be enabled.

Thanks for taking a look at this issue and hope I didn't take too much of your time.

No worries at all. You always provide really good bug reports :)
