Why doesn't child_process work?

Question

Node.js

Answer 1

var cp = require("child_process").exec;

cp("pwd", function(error, stdout, stderr) {
    if (error !== null) console.error(error);
    console.log(`pwd => ${stdout}`);
});

Answer 2

Specify the full path to pwd. If I'm not mistaken, child_process.spawn() ignores PATH under Windows.
