WebStorm TSLint: error: unknown option `-t json'

Question

My Angular2 project in WebStorm suddenly started to show for each TSLint .ts inspection

TSLint: error: unknown option `-t json'

Reseat

What TSLint version do you have? – Ikey

Using version [email protected] – Reseat

I was getting that same error on that same version. It's not really a fix, but I did get that error to go away by reverting back to an older version (specifically [email protected] and [email protected]). – Parmentier

Changed from [email protected] back to [email protected] fixed it for me, thank you! – Reseat

Fixed issue for me also. Downgrated [email protected] back to [email protected]. – Waggle

Answer 1

In my case I just reverted back from [email protected] to [email protected] and tslint started working again with WebStorm.
