I am quiet new to rabbitmq and currently trying to install Postgres listen exchange plugin at: https://github.com/aweber/pgsql-listen-exchange

I tried following the instructions listed there but i am getting following errors:

/bin/sh: escript: command not found

make[1]: *** [deps.mk] Error 127

make: *** [../rabbitmq-server/dist/.done.0.0.0] Error 2

I am currently working on Mac, not sure if it is because of i missing some essential libraries.

If you want just install the plugin you have to:

  1. Download the package here https://github.com/aweber/pgsql-listen-exchange/releases and exactly this https://github.com/aweber/pgsql-listen-exchange/releases/download/0.3.0-v3.5.x/pgsql-listen-exchange-0.3.0-v3.5.x.zip
  2. Extract the zip and copy the files into the rabbitmq plug-in directory, usually this : rabbitmq_server-3.5.4/plugins
  3. After that execute sudo ./rabbitmq-plugins enable pgsql_listen_exchange, and as result you should have:
The following plugins have been enabled:   
epgsql   
pgsql_listen_exchange

you are trying to rebuild the package, but if you want just use it, you don't need to rebuild it.

hope it helps

  • Does it mean it will enable the next time i run rabbitmq ? – Aditya Patel Jul 24 '15 at 13:58
  • Thanks, i checked the list it says it's explicitly working and running on rabbit@adityas-MacBook-Pro. – Aditya Patel Jul 24 '15 at 14:01
  • Hi Gas, When i ran the plugin what is the queue name which i should receive on in python script. I tried queue name :"test" in python and also ran the command in postgres: (postgres=# NOTIFY test, 'This is a test';). But didnt get any data in my receive script in python – Aditya Patel Jul 27 '15 at 07:02
  • Hi @AdityaPatel ! I'm sorry but I don't know how this plug-in works. I just know how rabbitmq works with the plug-ins. – Gabriele Santomaggio Jul 27 '15 at 07:14

Here is new version of previously mentioned plugin - https://github.com/anshmain/listen-pg-exchange

Now works with rabbitmq:3.12

Installation guide inside, it's pretty the same
