This was a problem with the version, i was using v0.6.12 which did not have that method, i upgraded to v0.10.0 which solved it, thanks to michaelt for pointing it out.
node js fs module says object does not have method appendFile

Question
I'm building a node js app(for learning) where i'm logging each operation into a file called log.txt
The logger module has the following code :
var fs = require('fs');
function write(data,filename)
{
var entry = 'Time: '+new Date();
if(filename !=null || filename != undefined) entry = entry+'\n\tFile: '+filename;
if(data !=null || data != undefined) entry = entry+'\n\tMessage: '+data;
entry = entry+'\n';
fs.appendFile('./log.txt',entry,function(err){
if(err){console.log('Log NOT Appended with data:\n\t'+entry);}
else{console.log('Log Appended with data:\n\t'+entry);}
});
}
exports.write = write;
now in my app.js i'm requiring it as :
var logger = require('./logger');
var fs = require('fs');
function ReadFile()
{
var data = fs.readFileSync('./config.txt');
if(data==null)
logger.write("Config data not found");
else
logger.write(data,"app.js");
}
ReadFile();
This throws me back an error saying :
Object #<Object> has no method 'appendFile'
However this worked fine earlier on a different pc, I noticed this when tried to run my app on my system.
