This error with OpenCV (I'm trying to use Node + OpenCV - as in node-opencv) has been driving me crazy. I've looked at many answers on StackOverflow or otherwise, and I think this could be a problem with the upgraded Homebrew or maybe with OpenCV. Unless it is a problem with the way I imported OpenCV.
Does anyone understand this/know what to do?

I was getting the same error and reinstalling Open CV fixed it. I ran
brew reinstall --build-from-source opencv.

When datejs is installed using npm and when a script (below) is executed, the following error is obtained:

datejs module exists under correct node_modules.Thanks in advance.
Try require('./node_modules/datejs/index.js');
I’m installing scrypt (https://www.npmjs.com/package/scrypt) from npm. The installation involves a node-gyp build step that builds a native node.js extension. When I then start my app, it fails with the following error:

at Object.<anonymous> (/home/xxxx/xxxx/node_modules/unfun-cms/lib/utils/password.js:3:16)
which is not so surprising, because
[xxxx#xxxx nodeapp]$ strings /package/host/localhost/gcc-4/lib64/libstdc++.so.6 | grep "GLIBCXX_3\.4\.21"
[xxxx#xxxx nodeapp]$
while
[xxxx#xxxx nodeapp]$ strings /package/host/localhost/gcc-5/lib64/libstdc++.so.6 | grep "GLIBCXX_3\.4\.21"
GLIBCXX_3.4.21
[xxxx#xxxx nodeapp]$
I have
export PATH=/package/host/localhost/gcc-5/bin:$PATH
export LD_LIBRARY_PATH=/package/host/localhost/gcc-5/lib64:$LD_LIBRARY_PATH
in my .bashrc, and gcc --version shows 5.2.0 correctly, so I assume these settings are alright.
So the question is, how do I tell scrypt the path to the correct libstdc++.so.6, namely the one at /package/host/localhost/gcc-5/lib64/libstdc++.so.6? (And why does it even get it wrong?)
EDIT:
This is a CentOS machine. I’m using node.js version 6.1.0, npm version 3.8.6, and I’m trying to install scrypt version 6.0.3, which is the latest version at the time of this writing.
EDIT 2:
I tried to statically link the library by editing node_modules/scrypt/binding.gyp, adding
'libraries': ['/package/host/localhost/gcc-5/lib64/libstdc++.so.6'],
to each of the four specified targets, and then running node-gyp rebuild.
I also tried changing this to
'libraries': ['-L/package/host/localhost/gcc-5/lib64', '-lstdc++'],
, which appears to be syntactically valid, too—but still, it tries to load the library from the wrong path at runtime.
I stubled with a similar trouble and had resolve it with a trick uses dynamic load of libstdc++.so.6 through LD_PRELOAD:
LD_PRELOAD='/path/to/lib/libstdc++.so.6' /usr/bin/nodejs app.js
When I compile code with
\> jx package bin/www.js myApp
\> packaging...
\> [OK] compiled file is ready (myApp.jx)
it successfully created myApp.jx and myApp.jxp
But when I executed command
\> jx myApp.jx
It gives errors as:

I dont think,the problem is with NPM, step by step compile each of the .js file, and introduce required NPM package one by one , you will get the solution.
Since it is not a JXcore issue (the app fails with node too), you might want to seek the problem related with js-bson: Failed to load c++ bson extension, using pure JS version.
For example I saw this answer: Failed to load c++ bson extension, and they say it could be fixed by reinstalling modules with npm install.
I am newbie to MEAN stack and Linux hence please forgive me if my question is too obvious and stupid.
I have hosted a Nodejs application on Openshift. While trying to start the application I am facing following error due to GLIBC library version missmatch:

Current version of GLIBC on Opneshift is 2.12.
One obvious solution which I know is to upgrade GLIBC on Openshift. However that is not feasible as I am not having sudo rights on openshift.
Is there any possible workaround to solve the same issue?
io.js released 1.0.1 version yesterday and, as the developers say, it's now possible to use classes without a nightly build.
But I'm not able to use ES6 classes without being in the REPL, e.g.:
$ iojs --use_strict --harmony_classes
> class Person {}
> [Function: Person]
But it I write it in a file, it doesn't work:
$ iojs test.js --use_strict --harmony_classes
class Person {}

What am I doing wrong?
The command line arguments are not actually applied to iojs. Change the command to
iojs --use_strict --harmony_classes test.js
it will work fine now.
