Question

Using phpstorm, trying to get mongoDB server up and running using nodeJS, i have mongo installed and have created the required folders on the c drive to store database, proceeded by going to command prompt and entering mongod, to get mongo db running....

checked npm ls,mongoose and mongo are listed fine, and are also present in my package json file.

when i try to run the index file from commmand prompt 'node index.js' i get the following error, see pic for details, i have included, the code used for setting up mongo... i have disable mongoserver from phpstorm repository, and use the one from the mongodb website

"mongodb": "3.0.0-rc0", "mongoose": "^5.0.0-rc2",

 var mongoose =require('mongoose'); //connect to mongoose mongoose.connect('mongodb://localhost/quaver'); mongoose.connection.once('open', function(){ console.log('connection has been made , and is running') }); mongoose.on('error', function(error){ console.log('Connection error',error); }); 

Answer 1

error sorted by omitting the following lines from the semver.js file, in the node modules folder in the current project

line 203,204

//re[COMPARATORTRIM] = new RegExp(src[COMPARATORTRIM], 'g'); //nodevar comparatorTrimReplace = '$a$2$3';

and line 232

// re[i] = new RegExp(src[i]);

mongoose now up and running
