Can't get mongojs (node-mongodb-native wrapper) to work Ubuntu 10.10

[Tim Skauge]

I used npm install mongojs to get the wrapper, but when trying to run
my app I get the following error:
node.js:195
throw e; // process.nextTick error, or 'error' event on first
tick
^
Native bson parser not compiled, please compile or avoid using
native_parser=true

I then tried to get the source from github and compile node-mongodb-
native myself. Then I get the following error when running make:

Any ideas to why this is failing and how I can make it work?

[Laurie Harper]

One option would be to bug the maintainer of mongojs and have them stop using native_parser=true ;-)

I don't know why the native BSON parser is failing to compile; it looks like you're missing the Node headers on your system; how did you install Node?

Installed node by getting source from github and compiled on my machine (./configure make make install).

How do I add the node headers to my system?

'make install' does it, but if you compiled from the master branch you're using 0.5.x-pre, which probably isn't supported. Unless you need to work against the bleeding edge for some reason, you should install the latest 0.4.x version instead.

If you *do* need to work against 0.5, you should try with 0.4 and see if it compiles cleanly; if so, you'll need to either wait for 0.5 support, or patch it in and send a pull request.

Installed the stable version of node and all my problems went away.

I didn't know there were stable and unstable versions of node. Just followed the guides that I found on how to install node.

Thanks for you help.

Hi, I encountered the same problem in installation using node v0.5.2.
It said that "node_events.h" was missing in bson.cc.
This is because in current Node.js ( v0.5.x) doesn't have
node_events.h .
I tried to modify bson.cc, but BSON extends EventEmitter,
which doesn't seem to be defined in any c++ sources, (instead, it is
defined in a file "node.js")
so I couldn't fix it.

Does anyone know the solution?

Please stop using the native parser. The js parser is better and
faster. I'm going to make a simple test at some point going forward
just to see if there is any point at all with a c++ parser but right
now it's slower than the js one.

Use the js == no problems with either the 0.4 or 0.5 branch.

[Navaru]

How to install it without the native parser or how to use it with 0.5
branch?

A few pointers please :)

[christkv]

npm install mongodb

Default install is without the native bson parser

[Laurie Harper]

I was gong to post the same reply until I realized the subject was mongojs, not just mongodb. I'm assuming that is the part that's enabling the native bson parser...
