I'm trying to follow the tutorial here: http://docs.couchbase.com/couchbase-sdk-node-1.2/

I'm using the most recent version of Node. I get the following exception when I try to run the example:

C:\Program Files (x86)\nodejs\Ken\hello-couchbase.js:3

var bucket = new couchbase.Connection({

^

TypeError: undefined is not a function

at Object.<anonymous> (C:\Program Files (x86)\nodejs\Ken\hello-couchbase.js:

at Function.Module.runMain (module.js:497:10)

at startup (node.js:119:16)

at node.js:929:3

I didn't get any errors when running "npm install couchbase" but did get a number of warnings (below). Any thoughts on what I should do?

npm install couchbase

Looks like the API changed in couc...@2.0.0 (released in November), but I can't find a changelog or API docs in the repo. So +1 for following semver and -1 for documenting the breaking change? I didn't look hard, could be somewhere other than the repo: https://github.com/couchbase/couchnode

Either way, if you change your dependency to couchbase@^1.0.0 (npm install "couchbase@^1.0.0" should do it) the example code you are following will probably "just work" as intended.

Thanks Ryan,

I tried version 1.0 but continue to get errors. I was able to install v1.1 without errors but still can't get the couchbase example to work. Any further suggestions?

You need to install the module inside your project, not inside your global node folder. While there are a few exceptions, dependencies are generally installed on a per-project/module/package basis.

If this is your first foray into node, you might be better served by following a more generic intro to node tutorial instead of the couchbase tutorial that appears to assume prior knowledge of node. I'm not familiar with any of them, but I'm sure someone on the list can come up with a few.

Thanks Ryan, ran NPM install couchbase@1.1 from my project directory and hello-couchbase.js worked. It makes complete sense to me why I should do this, I'm just new to package managers and Node.

That fixed the problem, thanks!

What's odd to me is that I expected to see a couchbase folder somewhere in my project folder. Nothing was added to my project folder. I question where it got installed and how do I deploy to other servers.

Thanks again for all the help!

The couchbase module would be installed into your project's local node_modules folder, so you should see it in there.
