Steps to Reproduce
While, I run "npm run dev" command after installing all the required packages as per your instructions, the application popped an error related to Browserlist.

Error

 ./node_modules/react-dev-utils/webpackHotDevClient.js

Maybe you are using old Browserslist or made typo in query.

I cannot seem to reproduce this error. It looks like an incompatibility between dependencies.
Have you tried reinstalling node_modules after deleting the package-lock.json and the node_modules directory?

[khizarkhizar]

Yes Davehowson, I did it (reinstall node_modules after deleting the package-lock.json and node_modules) more than one time, still facing the same issue.

[khizarkhizar]

I tried reinstalling for both node_module directories, one for server and the other for a client. but the error did not yet resolve.

I faced the same issue, Step I did to resolve this are:

1. Removed browserList from client/package.json
2. Deleted nodemodules and package.lock.json
3. Run npm install in ./client (Note don't run npm run client-install in root dir)

When using React please take a look into your package.json. You may find the following added there.

"browserslist": [
">0.2%",
"not dead",
"not ie <= 11",
"not op_mini all"
]
Remove "not dead", and run yarn run build again. Fixed the issue for me.
