Version mismatch error when installed via MacPorts

[jleaders]

On OSX, I need to use macports, because I run into issues with Brew. I uninstalled homebrew package manager and tried to get node to work:

I do a clean install of nodejs and npm

sudo port install nodejs npm

Let's just show that there is only npm installed, and no other modules.

$ ls /opt/local/lib/node_modules/ 
npm 

Trying to get a node package working, testing with appdmg

sudo npm install -g appdmg

Now here's the cryptic error. (NOTE: It worked with brew's version of NPM, earlier this morning)

$ appdmg
module.js:460
  return process.dlopen(module, path._makeLong(filename));
                 ^

Error: Module version mismatch. Expected 46, got 47.

What version of OS X are you using?

(I'm using node and npm installed via MacPorts, too. I'm having problems with the latest versions of node, but I haven't examined the problem so far, both due to lack of time and because I thought that the problem is limited to old OS X versions (I'm on 10.6.8). If instead the problem is in MacPorts, I'll surely try to debug this.)

I'm using 10.8.4 Mountain Lion. I tried with the latest version of node (5.1), and the older version (4.2) and got INVERSE results..

On 5.2, the message reads:

 Error: Module version mismatch. Expected 47, got 46.

On 4.2.2 I got

 Error: Module version mismatch. Expected 46, got 47.

Which lead me to believe there was some lingering brew version of node. So I ran this uninstall script and it fixed it, thanks to @nicerobot via https://gist.github.com/nicerobot/2697848:

curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh

Glad to see that you got it resolved :+1:
