This seems to be an issue with monorepos when webpack-cli is hoisted.

The workaround is to add the dependency to the monorepo root package.json but this shouldn't be necessary.

Yes it is a bug, not related to webpack-cli, bug on webpack-dev-server side

Hello,

I would like to know is a solution is currently available... I started webpack yesterday to improve and have more control on my application. This bug make me puzzled about it's because in the webpack tutorial a lot of manipulation use webpack-dev-server.

Hopefully it's a good place to ask my question.

Regards

[alexander-akait]

@hpachy Can you provide links?

[hpachy]

for example this one :

-https://webpack.js.org/guides/development/
-https://webpack.js.org/guides/build-performance/ (compile memory)
-https://webpack.js.org/guides/development-vagrant/
-https://webpack.js.org/guides/hot-module-replacement/ (webpack-dev-server --hotOnly)

for now I stoped here but I'm still following the tutorial, it's maybe my bad but I tried it and it's not working / not fixed so I just asking you if it s totaly fine or not ;)

regards

I'm still working on the tutorial and I found the same error just there:
-https://webpack.js.org/guides/production/

should be something like that I guess : webpack serve --config webpack.dev.js

If I find others link I'm gonna put there here

I ran the command npm-doctor.
It asked me to update my npm and node. I did that as mentioned. I even changed my environment variable path to c:/program files/nodejs, still getting the same error. Is the error related with the webpack-cli? It would be really helpful if I get some insight into this. Thanks in advance.
