To Reproduce Steps to reproduce the behavior:

1. Install NodeJS on Ubuntu 20.04 as explained in the https://github.com/nodesource/distributions/blob/master/README.md#debinstall
2. git clone https://github.com/dkackman/chia-repl.git && cd chia-repl
3. npm install

• OS: Ubuntu 20.04
• NodeJS: v18.7.0
• NPM: 8.15.0
• Chia version: 1.5.0

This is almost certainly because of node 18. I'll take a look but any chance you can use node 16 lts in the meantime?

[LeonidShamis]

Thank you for the prompt response!

Yes, I removed node 18 and installed node 16 and that fixed the issue:

leonid@asus:~$ node --version
v16.16.0
leonid@asus:~$ npm --version
8.11.0
leonid@asus:~$ whereis node
node: /usr/bin/node /usr/include/node /usr/share/man/man1/node.1.gz
leonid@asus:~$ whereis npm
npm: /usr/bin/npm
leonid@asus:~$

leonid@asus:~/dev/nodejs/chia-repl$ npm start -w chia-repl
