"Uncaught error outside test suite" on Ubuntu 18.04.3

[matthewlilley]

Latest hardhat and latest hardhat gas reporter results in 1) Uncaught error outside test suite with zero config setup, and with config setup.

Node LTS v14.15.1

We tried to debug this and it seemed like it might be tied to a specific Ubuntu setup, but the exact cause wasn't found...

Version info:

Description:    Ubuntu 18.04.3 LTS
Release:        18.04

Same issue here

@NotRealAI Do you have any more info that could help debug this? Are you also on this ubuntu version?

Ubuntu 19.10 / Node 10.15 here. Wish I had something more to give you.

Ok, that's helpful. Now we have four Ubuntu / Node configurations and three occurrences of the error.

Ubuntu	Node	ok	who

(This problem might not be os related, idk)

For people who also found this issue via google :)
Had such issue, removing 'eth-gas-reporter' helped.
Also for more error details you can run DEBUG='*' time npx hardhat

Ran into this issue just now running ubuntu 20.04, npm 8.1.0, node v16.13.0

hardhat version:
├── hardhat@2.6.4

mocha:
├── @types/mocha@8.2.3

chai:
├── chai@4.3.4

hardhat-gas-reporter:
├── hardhat-gas-reporter@1.0.4

Happy to provide any additional context for debugging here.

@stevieraykatz If you run npm list eth-gas-reporter in your project do you see more than one version?

[stevieraykatz]

Nope. Just the one that's inherited from this package:

└─┬ hardhat-gas-reporter@1.0.4
     └── eth-gas-reporter@0.2.22
