Cannot read property 'entryOption' of undefined

[Sweetyboy]

Hi,

I got this error when I try to launch the project "npm run start"

Could you help me please ?

Prompt error :

Estou com o mesmo problema!

This is happening because there's no package-lock file in this repository - which will cause a dependency update which leads to an wrong build.

Quick fix:
Go to your package.json file and remove all version modifiers there - ~ and ^ - this should be enough to run the project.

Right fix:
If you want to do the things right you must find which dependency (or dependencies) is breaking when you update it. You must stick the version only for those dependencies to still get updates for the healthy ones.

I could not make it work by removing the version modifiers, nor updating the WebPack and dependencies. Any other tips?

I think they want us buy this template, not for fee

You shouldn't try to update anything. Just remove the version modifier than run npm install and run:

npm run start

You just need to remove ^ from webpack-dev-server in your package.json file. I have opened a PR to fix this issue.

Maybe this code will help you,

npm install webpack-dev-server@2.9.7 --save-dev

Still having problem

This solves the problem for me, "npm install webpack-dev-server@2.9.7 --save-dev". Thanks @muzeyr
