I'm using the released version 4.5.0.

ERROR in ./src/elm/Main.elm

Removing node_modules and installing again helped.

I had the same issue. We use yarn and I updated the dependency in package.json and ran yarn install - so it did update the elm-webpack-loader but seems like it didn't run additional scripts that builds elm compiler binaries(?).

Maybe similar problem rails/webpacker#420

@nik-kor fixed! Going to leave it open for future issues

Feels like you should close this now, as new issues should probably be posted as a new issue in fact

For me the problem was actually that, Because I had created the project with the create-elm-app There was one of the initially modules created by the create-elm-app that was using this library https://package.elm-lang.org/packages/krisajenkins/remotedata/latest/RemoteData which was conflicting with the Http 2.0.0 when the Http 2.0.0 was a direct dependency . When I created the project I installed the elm/http dependency at the end end the version 1.0.0 was picked up automatically. So what I did was delete all dependencies and first install the core (http, html...) first and then I was able to get the http 2.0.0 but I got this problem.
