Require error with io.js@2.2.x

[blond]

In io.js@2.2.0 were changes with require — nodejs/node#1801

For real file system require works well, but with mock-fs fail with error.

How to reproduce:

var path = require('path'),
    fs = require('fs'),
    mock = require('mock-fs');

mock({
    'file.js': 'module.exports = 10;'
});

var filename = path.resolve('file.js'),
    contents = fs.readFileSync(filename, 'utf-8');

// File exists
console.log(contents); // module.exports = 10;

var val = require(filename); // throw error

console.log(val);

Expected:

module.exports = 10;
10

Actual:

module.js:334
    throw err;
          ^

Doesn't look like there would be any way to fix this in mock-fs 😞

[blond]

May be need to mock Module.require?

Please reopen if this is still an issue with the latest Node. We may need to document it as a limitation.

The same problem with Node@4.x and Node@5.x.

👍 reproduced this error in Node 4.x.

@tschaub What do you think about mocking require (or something) in node 4.x+ via public API?
