Node.js - nodeunit or Make and node-jquery compatibility issue

[thomasoriis]

When I try to run a unit test I get following error:

C:\users\thomas\chap02\node_modules\jquery\lib\node-jquery.js:10
window.XMLHttpRequest.prototype.withCredentials = false;

I am developing on windows 7 with Cygwin so I have a shell in some flavor.

Do you know a way to keep modules code out of the test scope - no need to test module code (already tested)?

Or do you know how to make this work?

Thanks ; )

I've seen some other folks come across this issue as well... I didn't seem to have it until I downgraded to Node 0.8.14 yesterday, in Node 0.9.2 it wasn't doing this to me.

Try reinstalling the jquery module and see how you go.

Run this in the chapter's directory:

npm install jquery

[thomasoriis]

Decided to install a visualbox on my windows machine and installed ubunto. Than I had the issue again when i installed jquery I noticed i needed make g++ - C++ build essential. I installed it and reinstalled jquery and then the make test also worked. However i also installed nvm and use node0.9.2. So now make test works - and all tests evalutes to green ; ) Thanks saved me a lot time.

thomasoriis, see my answer #10 here:

[thomasoriis]

Thanks Don - and thank you for your book. Yes that would solve the problem - however I am also developing an other application that needs more of jquery. But the link can help others I hope. Btw maybe you should point to sitepoint forums from the books site. I had to write to books@sitepoint.com and was directed to this forum. I would have saved me a lot of pain and efford : )

[garyklinecc]

Don, could you repost that link above? It does not appear to be working

Stuck in chapter 2 at the moment.

[Don Nguyen]

garyklinecc, I can't locate the post even after searching my entire history. I will check with the admins to see what has happened to it. In the meantime if you post what issues you're having I'm happy to look at it afresh.

[garyklinecc]

Don, I'm having the same error message as thomasoriis reported. When I use npm install jquery, it runs into errors like so:

Between these errors (Python is required?), and the use of Mocha to do test-driven development (requiring "make" to be available), I'm wasting my time using Windows as a node.js development environment. Unfortunately, its the only platform I currently have.

I'm debating whether to continue forward with the book in a Windows environment (and simply ignore/work around the code that fails (eg Mocha and jQuery), or just wait until I repurpose an older machine with Linux. Apparently the book's code was written on a Linux or Mac.

I like how the book explains each section of code, and I am excited to start using node.js for a particular project of mine. I really do want to finish the book, and will probably just work around the features that give me difficulties.

Hi garyklinecc and Don,

I'm experiencing very similar errors, and I'm working on a Mac, OSX 10.8.

I'm generating errors similar to thomasoriis and garyklinecc, errors when running make test in chapter 02, and then errors when reinstalling jquery with npm install jquery.

I've tried to reinstall jquery via (npm install jquery), and I've update my node.js version to 8.15, but no change.

I did all my testing with the book's example files to ensure that it wan't an error on my part.

The book is fantastic, and I'd love to be able to continue working through the rest of it. If there's any extra information I can provide to help find a solution, please let me know.

Thanks for any advice.

Regards,
Brent

The problem is related to the following bug in node-jquery:

https://github.com/coolaj86/node-jquery/issues/35

The work around is to remove jQuery. It was mainly there as an illustration of what's possible it's not an essential part of the project. The cloning function can be replaced as follows:

https://gist.github.com/4167847

This will also require a new package.json:

https://gist.github.com/4167853

Please let me know if there are still further issues

[garyklinecc]

Don, thank you for posting the modified code.

I ended up coding a cloneExchangeData() function, which was actually a good opportunity to learn more about Javascript. Hopefully Brent or someone can post after using the modified code.

Onward and upward!

Don, it's fantastic that you're such an active member our community. Thank you for posting the workaround.
