lighthouse CLI gives "Unexpected token" error on Ubuntu 20.04.1

[alex4200]

Provide the steps to reproduce

1. I installed lighthouse on Ubuntu Linux 20.04.1 as follows:

 sudo npm install -g lighthouse
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
/usr/local/bin/lighthouse -> /usr/local/lib/node_modules/lighthouse/lighthouse-cli/index.js
/usr/local/bin/chrome-debug -> /usr/local/lib/node_modules/lighthouse/lighthouse-core/scripts/manual-chrome-launcher.js
npm WARN notsup Unsupported engine for lighthouse@7.0.0: wanted: {"node":">=12.13.0"} (current: {"node":"10.19.0","npm":"6.14.4"})
npm WARN notsup Not compatible with your version of node/npm: lighthouse@7.0.0

2. Running lighthouse google.com results in the following error message:
   /usr/local/lib/node_modules/lighthouse/lighthouse-core/gather/driver.js:68
   _traceCategories = Driver.traceCategories;
   ^

SyntaxError: Unexpected token =

    at Module._compile (internal/modules/cjs/loader.js:778:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10)

What is the current behavior?

I get an error message

What is the expected behavior?

Command runs without error message.

I think this could be your issue:
npm WARN notsup Unsupported engine for lighthouse@7.0.0: wanted: {"node":">=12.13.0"} (current: {"node":"10.19.0","npm":"6.14.4"})

I ran into the same problem and upgrading to node 12 worked.

Thanks, upgrading to node 12 also fixed the issue on my side.
