Hi @matt-roe! Can you update the issue so that it includes more information about what your are attempting to do? Also, can you please use code blocks?

What do you mean when you say "Followed install steps on ubuntu 18.04"? Are you attempting to run the colony-example-vue package on a virtual machine? I'm also a bit confused why you are running yarn commands with sudo and this might be related to the issue.

I was setting up colony-example-vue locally on ubuntu. Following the instructions I set things up with docker. Sudo probably wasn’t necessary there, tried things both ways when troubleshooting. Essentially, it is fixed with that lower version of core-js so I think you just need to update the dependencies to that older version, or maybe you can add some packages I was seeing as potential solutions. It seemed like a change to core-js in version 3. Sorry about that, I will put things in blocks next time. Matt Roe

No problem! You can also edit the issue description.

What packages were you seeing as potential solutions?

Also, feel free to open a PR that sets core-js to 2.6.9 rather than ^3.1.4. It looks likes the issue is might be a breaking change in version 3.
