Unfortunately, composer does not offer a reinstall command so we have to remove `prooph/event-store` package from the vendor folder manually and install it again using `--prefer-source` flag. ``` $ rm -rf vendor/prooph/event-store $ docker run --rm -it -v $(pwd):/app --user="$(id -u):$(id -g)" prooph/composer:7.2 install --prefer-source ``` Supersedes Event Machine ------------------------ [](#supersedes-event-machine) The first version of this project is called Event Machine and can be found in another repo: . We had to change the name due to naming conflicts with other projects. In fact, Event Engine is a newer version of Event Machine using the same concepts.
