FB CTF - SyntaxError: Grunt is not generating JS Files

Installing prod:

This is the error message that I am getting when I try to install by any given method(direct,docker and vagrant):

try it

-> # apt remove nodejs -> # curl -sL | sudo -E bash - -> # sudo apt-get install -y nodejs 

Probably, if it is not version 12, an error appears

On Windows install the latest version of node.js and the error should disappear.

Was working on getting FBCTF up, tried to search everywhere but no one has a fix. Found a fix myself.

nano package.json 

In package.json, change from

"grunt": "^1.0.1", 

to

 "grunt": "1.0.1", 

The "^" seems to update the version of grunt to 1.3.0 (As of writing this) which apparently is not compatible with the FBCTF which have not been maintained for 2 years.
