Cannot load StringPrep-0.1.0 bindings. You may need to `npm install node-stringprep'

Hi guys,

Not sure if it's alright to post this here.

I deployed node-xmpp. No error messages during installation. But when I tried running a script, it prompted me to go install StringPrep.

Cannot load StringPrep-0.1.0 bindings. You may need to `npm install node-stringprep'

As prompted, I npm install node-stringprep, and I got the following errors.

Can you raise this against node-stringprep module please? https://github.com/astro.node-stringprep.

node-stringprep isn't a requirement, its just giving you a warning as its better to have it installed.

Also I haven't tested any of the node-xmpp related projects on nodejs > v0.8.X so a temporary fix might be to downgrade to a 0.8 version in the meantime.

Thanks!

I am having the exact same issue. Relevant software versions:

OS: Ubuntu 12.04
Node: 0.10.10
node-xmpp: 0.4.4

Perhaps downgrading to 0.8 would work, but since this isn't a requirement, I'll just wait for node-stringprep to be updated with a fix. Thanks.

Also, isn't this issue already on node-stringprep?

[lloydwatkin]

In which case I'm going to let the issue on node-stringprep highlight the issue. Thanks.

[aensley]

Is #26 the issue that highlights this? Just want to make sure I can track it.

[lloydwatkin]

@flamadiddle I'm not 100%, as I've had node-stringprep on a lower priority. I'll give #26 a go this evening and publish if all looks ok.

[aensley]

Just tried to install 0.1.6, and I'm still having this issue. I don't see any other issue or PR referencing this. Re-open?

[lloydwatkin]

Try 0.1.7 just pushed :)

We missed the package.json update

[aensley]

I just tried again :-) with 0.1.7, and still no joy.

[lloydwatkin]

@flamadiddle hmm strange, all working here on ubuntu 13.04.

Quick check do you have libicu-dev installed? If so maybe try npm i -g node-gyp and try again.

[aensley]

That was it. I was missing libicu-dev. After installing that, installing node-stringprep@0.1.7 went perfectly. Sorry if I missed something about that requirement in the documentation.

[lloydwatkin]

No worries. Glad to hear that its all working!
