TypeError: optionDefinitions.flatMap is not a function

[pietro-coretto]

I installed via npm and I get this

$ bibtex-tidy  myrefs.bib
/usr/local/lib/node_modules/bibtex-tidy/bin/bibtex-tidy:5342
var OPTIONS = new Set(optionDefinitions.flatMap((def) => Object.keys(def.cli)));
                                        ^

I suppose it may be an issue with my java settings, any hint?

Could you check your node version?

node -v

Currently bibtex-tidy requires at least v11.15.

Could you also let me know your OS and how you installed node?

[pietro-coretto]

I am on Linux Elementary OS 5.1 and it seems that apt manager keeps node back to 8.x

~$ node -v
v8.10.0

I tried to install it via snap but it didn't work. After some trial, I completely removed node with

apt-get purge node

and then I installed the latest stable version 16.x from the official repo (instructions for debian/ubuntu distros) doing

curl -fsSL https://deb.nodesource.com/setup_16.x | bash -
apt-get install -y nodejs

The complete documentation is here

https://github.com/nodesource/distributions#debinstall

Therefore this solved the issue

Thanks

Thanks for reporting back. Glad you got it working.

I'll leave this issue open because bibtex-tidy should give a better error if it's an unsupported node version.
