No because this is related when creating a new CRA app.

@germanamz see https://github.com/facebook/create-react-app/issues/11778#issuecomment-996488034 - from my point of view it is as intended. (yes potentially a breaking change, why it was released as part of v5)

If installing globally on the system I don’t think theres a safe way of detecting the intent when creating a new project to use either yarn or npm - therefor npm will be used as default. (@lukekarrys please correct me if I’m wrong) (global npm install of packages are generally not recommended)

I’ll close the issue - let me know if you if yarn create react-app doesn’t produce a yarn based project or if npx create-react-app doesn’t produce a npm based project.

So is there any options we can use? @lukekarrys @raix or is this a bug?
