Preact-cli: Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3"

[ajay28kumar]

I'm using preact-cli version 2.2.1

Do you want to request a _feature_ or report a _bug_?
bug

What is the current behavior?

yarn start is throwing an error if I'm adding jest into my node-modules. I'm putting error message below:

✖ ERROR (webpack)-dev-server/client/index.js
Module build failed: Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3".
 If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. 
Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel. 
(While processing preset: "/file-path/node_modules/@babel/preset-env/lib/index.js")

If the current behaviour is a bug, please provide the steps to reproduce.
adding jest and enzyme testing library into my package is throwing an error. Attaching my package.json:

What is the expected behaviour?
yarn start should start my webpack-dev server

If this is a feature request, what is motivation or use case for changing the behaviour?

This is because the templates still refer cli V2.
This will be corrected as soon as we hit stable

[ajay28kumar]

@prateekbh is there any way to work around things? I want to upgrade my preact to 10.x.x. If there is any postinstall script or any workaround in my system to get it done with preact-cli

[reznord]

CLI v2.2.1 hasn't been updated for long.

@ajay28kumar can you give preact-cli@rc a try and see if you are still facing this issue?
