tput: No value for $TERM and no -T specified

[styfle]

I'm seeing this error when process.env.TERM is undefined and process.stdout.isTTY is undefined.

tput: No value for $TERM and no -T specified

It happens on line 60 when tput cols is executed.

How are you seeing the error? Errors are silenced by the try/catch. Or do you mean you see it in the terminal as just printed output?

[styfle]

Its printed to stderr even though there is a try/catch.

You can reproduce if you deploy to ZEIT Now.

I added some console.log() prior to each line to determine exactly when it happens.

"there was an error" is the message I put in the catch

Here's the minimal steps to reproduce:

npm i -g now
git clone https://github.com/styfle/bug-term-size-tput
cd bug-term-size-tput
now

It will look like this: https://zeit.co/testing-internal/bug-term-size-tput/5howzk8xs
