Not able to connect to Oracle using NodeJS

Question

I am trying to run a NodeJS(v0.10.36) file which contains connection to Oracle database.

When I try to run the project, I get the below error.

M1318657:testOracle yogeshJC$ node app.js

module.js:340
throw err;
^
Error: Cannot find module '../build/Release/oracle_bindings'

at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Module.require (module.js:364:17)

app.js contains simple script to connect to Oracle Database.

I have followed the instructions here to install oracledb

Oracle Version : 11.2

Following environments have been set :

OCI_HOME
OCI_INC_DIR
OCI_VERSION
OCI_LIB_DIR

Any leads to resolve the issue would be appreciated.

Edit :

sudo npm install oracledb

Answer 1

You have some conflicts. The error you pasted refers to node_modules/oracle which is the older, unsupported module for Oracle DB and is not the oracledb module you show being installed.

Recommendations:

• remove the obsolete oracle module
• consistently use the newer, better oracledb module.
• check the install instructions : node-oracledb doesn't use OCI_VERSION or OCI_HOME
• try an example that uses oracledb
• optionally use the new 12.1 Instant Client for OS X
• upgrade Node to a secure patch level. And preferably use recent release like 4 LTS or 6.
