Syntax error on "=" NodeJs in Ubuntu 20.04

I have developed a NodeJs(v10.19.0) server on windows.
I now need to transfer it to a linux server running Ubuntu 20.04
When I try to start the server, I have a syntax error on a "=".

Here’s the complet error:

    static websiteRegex = /^(https?\:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})(\/[\w\W]*)*$/gm

SyntaxError: Unexpected token =

[nodemon] app crashed - waiting for file changes before starting...

Here’s the code that outputs the error:

class ScrapingBot {
    static websiteRegex = /^(https?\:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})(\/[\w\W]*)*$/gm
    static phoneRegex = /\+?\d{1,4}?[-.\s]?\(?\d{1,3}?\)?[-.\s]?\d{1,4}[-.\s]?\d{1,4}[-.\s]?\d{1,9}/g;
    static addressRegex = /(([a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ'.]*\s)\d*(\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']*)*,)*\d*(\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']*)+,\s([\d]{5})\s[a-zA-Z-éÉèÈàÀùÙâÂêÊîÎôÔûÛïÏëËüÜçÇæœ']+/

I set up Git with nano if that helps…

I have already tried to replace the "=".

>Solution :

As you can see in here, static class fields are not supported as of Node 10 ->
