Getting an issue with string-kit

[ghost]

Getting this error when trying to run it. Is this a problem with this program? Or is this a problem with something else.

/home/fireboltaa/AniCli/node-anime/node_modules/string-kit/lib/format.js:327
                markupTarget = this.shiftedMarkup?.[ runtime.shift ]?.[ markup ] ;
                                                  ^

It's probably because of old nodejs version, try upgrading nodejs

That was the problem, thanks. I had installed node using apt on ubuntu, and apparently ubuntu cannot install the most recent node version, so I did

sudo npm i -g n
sudo n lts
