I'm running a Python script through a child process in Node.js, like this:
require('child_process').exec('python celulas.py', function (error, stdout, stderr) {
child.stdout.pipe(process.stdout);
});
but Node doesn't wait for it to finish. How can I wait for the process to finish?
Is it possible to do this by running the child process in a module I call from the main script?
You should use exec-sync
That allow your script to wait that you exec is done
really easy to use:
var execSync = require('exec-sync');
var user = execSync('python celulas.py');
Take a look at: https://www.npmjs.org/package/exec-sync
