Unable to execute a node module within PHP

Question

After installing the necessary modules, the following command

azure account -help

works as expected. However, when I invoke the same command from inside PHP using exec().

exec('azure account -help',$output,$responseCode)

and print the output, I get

$output: [] (empty array) and $responseCode: 8

I've tried executing the module using the command 'node'. Ex

node /usr/lib/node_modules/azure-cli/bin/azure.js account -help

This also works on command line but not through PHP's exec.

Edit: Redirecting the stderr with the following command:

exec('azure account -help &2>1',$output,$responseCode)

gives these details:

,E === undefined) && (process.env.HOMEDRIVE === undefined))) {throw new Error(, ^,Error: HOME not found, unable to store Streamline callback cache, at Object. (/usr/local/lib/node_modules/azure-cli/node_modules/streamline/lib/compiler/compile.js:278:90), at Module._compile (module.js:456:26), at Object.Module._extensions..js (module.js:474:10), at Module.load (module.js:356:32), at Function.Module._load (module.js:312:12), at Module.require (module.js:364:17), at require (module.js:380:17), at Object.

What can I try to debug this further?

php is not bash and won't search azure command in PATH. Try calling it, using full path to azure. — user4035

The problem was solved by invoking exec() and providing a HOME env variable:

exec('HOME=/tmp/ azure account -help 2>&1');

php do not know about node , so make sure you specify full path of nodejs something like

exec('c:/nodejs/node.exe mynode_scripts.js',$retr_err,$retr_val);
