webpacker: Heroku: can't find executable webpack for gem webpacker (Gem::Exception)

After upgrading to the master branch of this repository, I get the following error when compiling on Heroku:

       Compilation failed:

Why was a breaking change introduced in a minor version?

@AlexandrePerdomo Are you sure you are installing latest version of webpacker and npm package?

bundle update webpacker
yarn add @rails/webpacker

Are you able to compile locally?

Same for AWS Elastic Beanstalk , after upgrading webpacker from 3.2.x to 3.3.x you have to update binstubs with bundle exec rails webpacker:binstubs

UPDATE: opps, it’s actually written in the CHANGELOG.

Sorry for the noise. Basically what was suggested above works. We just have to run rails webpacker:binstubs in all packages that require webpacker. Thanks. 😃
