I´ve tried rm-r t2-cli, reinstalling it and still the same error -

It happened after I ctr+c in the middle of a t2 run index.js and after that I starte having this issue. How can I resolve it ??

I updated t2-cli and tried running t2 run index.js again, but I get the same error:

$ t2 version

I managed to solved it!

I uninstalled NODE, reinstalled 6.10.3LTS and resintalled CLI and it worked
