Possible Solution

I tried to manually install the apps/admin package independently by using yarn install, and I received the following error:
error [email protected]: The engine "node" is incompatible with this module. Expected version "^8.12.0 || >=9.7.0". Got "8.10.0" error Found incompatible module.

Installing with npm resulted with the following errors
npm ERR! No compatible version found: theme@^1.0.0

Did you try installing a newer version of node? Using yarn may have given you a more detailed error the first time because or the whole yarn-workspace/lerna thing?

Hey @tjrexer, to be honest, we're running everything on node ^10.14 locally, so maybe try installing at least that? A greater version should also work, but try at least 10.14.

Btw. a great tool to manage you node versions and switch them instantly is https://www.npmjs.com/package/n.

Let us know how it goes :)

[tjrexer]

@Pavel910 that solved it, was running v8.10 as that's what was available through default package managers. Updated to current release v13.7 and that succeeded. Might be worth adding a version check for nodejs on create to at least require minimum that you're running.

Not going to close the issue in case you want to add that as an enhancement.

[Pavel910]

Great! Actually we did have a check, but it was for node 8.10; updated it for the upcoming release 👍

@Pavel910 can we close this?

[Pavel910]

Yep; closing.
