I have the same issue also, repeatable on both on my WSL Ubuntu 20.04 and my VirtualBox install of Ubuntu 20.04.

In the meantime, you can specify the specific Docker image you'd like to use in your Dockerfile via mhart/alpine-node:10. We currently recommend using Node 10.

For those of you using Node 14, you'll need to launch ganache-cli via node 8, 10, or 12 until this is fixed. For example, run nvm use 12 && npm install ganache-cli -g to install for node 12, and then run ganache-cli with nvm use 12 && ganache-cli.

Sorry for the temporary inconvenience while we update ganache-core internals to Node 14.

Same issue on Ubuntu 20.04. No docker, just trying to run from terminal. I am using node 14 and have used the above from davidmurdoch for now. Is this going to be fixed?

Same issue here, also on Ubuntu 20.04

Looks like this issue is specific on Node v14 and not specific to your OS. As a temporary workaround you can:

1. Just downgrade your node js version to 12.x, reinstall the package again (npm i ganache-cli -g) and don't worry until this issue is fixed.
2. If you need features of Node 13+, use nvm to use Node v12 for ganache-cli as mentioned in above reply.
3. if this is causing your CI tests to fail, remove 14.x from your nodejs version matrix for now.
