3.x using Object.defineProperty with process.env failed

[pmq20]

Originally discovered by @popomore .

In io.js 3.x, Using Object.defineProperty with process.env failed in that, process.env will not actually store the value into the environment variables but on the object itself. This also results in subsequent delete operation failed.

Other objects work fine.

Closing as we are not planning to do another io.js release. (#3465)

setter is not work for me.

Object.defineProperty(process.env, 'SHELL', {
	get: function () {
		console.log('get');
		return '';
	},
	set: function (value) {
		console.log('set');
	},
	enumerable: true,
});
console.log(process.env.SHELL);
process.env.SHELL = 'test';

E:\work\git-bash-shell (os -> origin) ([email protected])
$ node -v
v9.2.0

E:\work\git-bash-shell (os -> origin) ([email protected])
$ node test.js
get

I found the right way.

Object.defineProperties(
	Object.getPrototypeOf(process.env),
	env
);
