Easy plv8 on OSX

README.md

Heroku runs plv8 v1.4.2 (checked on 1st April 2016). On OSX it's easiest to install v1.4.3 since that allows V8 3.15 which is available via homebrew. (1.4.2 wants V8 3.14.5).

To install:

brew install v8-315
pip install pgxnclient
LIBRARY_PATH="/usr/local/opt/v8-315/lib" CPATH="/usr/local/opt/v8-315/include" pgxnclient install plv8=1.4.3

To test it worked:

$ psql
# CREATE EXTENSION plv8;
CREATE EXTENSION
# DO $$ plv8.elog(NOTICE, "Hello World") $$ LANGUAGE plv8;
NOTICE:  Hello World
DO
# DROP EXTENSION plv8;
DROP EXTENSION
# 

UPDATE: if installing newer plv8 against newer Postgres on newer OSX then do NOT install v8 from homebrew - it's out of date and causes issues. Uninstall it before continuing:

brew uninstall v8
brew uninstall v8-315

You can then follow the plv8 install instructions and they should work, plv8 will automatically download v8 as part of the make process 👍

@benjie 4 years later, this thread is a top result for the subject. Still true in your opinion?

🤷‍♂️ I don’t use plv8 any more
