OS: Windows 7 64-bit
Need to do parsing xml-file using Node.js.
Using a library for parsing xml2js.
Xml2js installed using the command "npm install xml2js".
However, if you run the code:
var fs = require ('fs'), xml2js = require ('xml2js');
var parser = new xml2js.Parser ();
fs.readFile ('<path to the xml-file>', function (err, data) {
parser.parseString (data, function (err, result) {
console.dir (result);
console.log ('Done');
});
});
an error:
module.js:340
throw err;

Answer 1

I was also facing the same issue. Here's what I did:
Install the module using following:
$ npm install -g *module_name*
Then go to any parent dir of your project dir (it can be project dir itself) and run the following command:
$ npm link *module_name*

Answer 2

Make sure that the directory ./node_modules/xml2js exists.
When you run npm install somemodule at D:/test, it will be stored to D:/test/node_modules/somemodule, then you can require this module in D:/test/*.js, and you can not require it at D:/other/place/*.js. If you hope the module can be required anywhere you should run:
npm install somemodule -g

I had a similar issue and even tried the fix mentioned by Lellansin, but it didnt help. There were some issues with npm cache and I had to clear it using the command:
npm cache clean
And it worked for me.
