I installed CouchDB (to run the local npm registry) and you need to find the local.ini file to configure the couch settings.
How to find local.ini file?
Follow these steps to display the chain of configuration files that CouchDB uses, which should include the local.ini file:
couchdb -c
Output Example:
/usr/local/etc/couchdb/default.ini /usr/local/etc/couchdb/local.ini
