this is a very common issue (https://www.google.com.ua/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=js-bson%3a%20failed%20to%20load%20c%2b%2b%20bson%20extension%2c%20using%20pure%20js%20version).
Such issues often occur if bson was compiled against a Node version different from the one you run your application with.

I am new to phant and i cannot find a suitable documentation on phant using mongodb. because i have lots of data and it memory overflow occurs. and finally i fell into following error:
HTTP output: { [Error: EMFILE, open 'phant_streams/4d16/83403f7611e5810d57f88174fbef/stream.csv']

except this sometimes following error also occurs:

thats why i want to use mongodb to prevent this error. i searched about this and finally found sparckfun library for mongodb:
https://github.com/sparkfun/phant-stream-mongodb
i installed this but nothing happened as data still not string into mongo.
so, How will i store phant data into mongodb ?
I had the same problem, specifically trying to deploy my own Phant instance on Heroku (since I wanted to circumvent Sparkfun's 50Mb limit). After some dabbling with versions of the mongodb and mongoose libraries, I successfully forked and modified their repository so that you can either run it locally or directly deploy on heroku (just make sure you provision a MongoLab add-on). Check out my fork here: https://github.com/davidlago/phant
Hope this helps!
I have installed all the prerequisites for a mean application(MEAN) as described in Meanjs Official website
I want you to look at this particular error I am getting and that too when I am offline.
But it does work well when I am connected to internet.
Help me Try looking at the error below:
Could not connect to MongoDB!

Did you start mongodb: try typing mongod into the terminal
I have my MongoDB server running on localhost:27017, and while I can usually run my Node.js app fine, when I disconnect from the internet Mongoose throws the error
Error: failed to connect to [localhost:27017]
Note that I can still connect to the MongoDB server from the Mongo shell client. Also, if I start up my app first and then lose internet connection, my app can access the database fine offline. So why can't it start up without internet?
EDIT: here is the error in full
events.js:85

Edit: wording
Use 127.0.0.1 instead of localhost. By turning off your wifi interface the OS is no longer able to resolve localhost.
Consider node-offline-localhost.
Add the following before the breaking code:
require('node-offline-localhost').always();
And it just works (hopefully), at least until RFC 3493 gets fixed.
Full disclosure: I authored this package to streamline https in my dev environment when offline.
I'm using karma and jasmine for some unit testing. I'd like an html output instead of checking the console / terminal and found this: https://www.npmjs.org/package/karma-htmlfile-reporter which is perfect for my requirements.
When I run it I get an error :
`ERROR [karma]: [TypeError: Cannot call method 'push' of undefined]

I've hunted on google for an answer but yet to find one, if I remove the 'html' from the reports in the config it works fine. I've not used jasmine / karma before so unsure where to look for help.
The part of the config related to reports: `
reporters: ['progress', 'html'],
htmlReporter: {
outputFile: 'tests/units.html'
},``
Thanks for any assistance.
I switched to karma 0.10 and everything works.
$ npm uninstall karma
and run following in project root:
$ npm install karma#0.10
Good luck

I'm using one of the example scripts on the github page for node-redis. I'm on Debian Squeeze.
The main problem is not with your code (of course it could recognize the error sent by the server) or with the node redis module but with the Redis server.
You need to upgrade it to a newer version, HSET command is supported since version 2.0.0.
