ReferenceError: URL is not defined when trying to Run lighthouse reports on the command line in linux

I have chrome, LTS version of Node, and lighthouse already installed but get the following error when I try to run an audit:

/usr/local/lib/node_modules/lighthouse/lighthouse-core/lib/url-shim.js:36
class URLShim extends URL {
                      ^

ReferenceError: URL is not defined
    at Object.<anonymous> (/usr/local/lib/node_modules/lighthouse/lighthouse-core/lib/url-shim.js:36:23)
    at Module._compile (module.js:652:30)
    at Object.Module._extensions..js (module.js:663:10)
    at Module.load (module.js:565:32)
    at tryModuleLoad (module.js:505:12)
    at Function.Module._load (module.js:497:3)
    at Module.require (module.js:596:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (/usr/local/lib/node_modules/lighthouse/lighthouse-core/lib/network-request.js:14:13)
    at Module._compile (module.js:652:30)

After installing all that is required, I try to test it and get the above error.

lighthouse https://www.bbc.co.uk

As I understand it you type lighthouse on the command line followed by the url of the site you're trying to run an audit against. But I keep getting :

ReferenceError: URL is not defined.

Am I doing something wrong. PLEASE HELP.

I had the same issue. Your node version is outdated. Check it by running node --version

If it's less than 10, then you've found your problem.

https://nodejs.org/api/globals.html#globals_url

To update node:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Then check you node version again:

node --version

Optionally, you can also install latest with sudo n latest , but I would recommend going with stable.
