I got this error in running heroku run rake sunspot:solr:run
rake aborted!
You need a Java Runtime Environment to run the Solr server
is there a way i can install jre in heroku?
回答1:
You cannot install the JRE on Heroku, and thus you cannot run Solr from a Heroku worker.
If you want Solr in Heroku, you'll have to use the Websolr addon, or start an EC2 server and run your own copy of Solr from there.
