Hmmm, I haven't seen this. Seems like a borked gyp install somehow. Perhaps try re-installing?

[rex]

I can confirm that this is a valid error, and we've tried reinstalling multiple times. Here is our log, running on an Amazon cloud instance:

Any ideas? :-/

[tj]

probably just a funky package manager install, I'll try from source or sth tomorrow

[TooTallNate]

@visionmedia Is this using the debian nodejs package or something?

[rex]

@TooTallNate I'm sorry to keep intruding, but I just wanted to point out that the error I posted was generated by a server using Yum's EPEL package manager on a RedHat-based Amazon image, installed using yum install nodejs. Attempts to use the npm version of node-gyp were fruitless, as I believe that the yum-installed node-gyp is used by default. It is weird, though, because our other servers haven't had any issues with it. To be honest, we're not utilizing dependency version locking nearly as well as we should be (npm shrinkwrap et al), so this could very easily be a breaking change in the API of any one of those dependencies.

That last part is purely speculation, of course, and not very helpful, but I wanted to provide as much feedback as possible.

Edit: I am not sure how much it helps, if at all, but I noticed something weird when running npm -g list:

npm ERR! invalid: inherits@2.0.0 /usr/lib/node_modules/inherits@2
npm ERR! not ok code 0

Subsequent attempts to npm -g update were not helpful. Though now that I'm thinking about it, I am not sure when last we cleared the npm cache. I'm going to try that and see what happens.

Edit 2: Nope, npm cache clean didn't help. Even ran npm -g install inherits and it didn't fix the dependency bug. I am now completely in agreement with @visionmedia on this one, it seems to be a dependency bug somewhere. @TooTallNate if you need more info about the machine that created this error or anything else, please let me know so I can help get this resolved. :)

Edit 3: For what it's worth, the server in question is running Python version 2.6.8.

Please help !

[tj]

yeah the package manager ones seem pretty borked

[tj]

yup re-install worked for me, so I guess just don't ever use the package managers haha

[laithshadeed]

For me it got fixed by replacing python2.7 by python2.6. As per https://code.google.com/p/gyp/source/browse/trunk/DEPS#19 , it seems that gyp depends on python 2.6

On Ubuntu Saucy:
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python2.6
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.6 20
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 10

you can switch between 2.6 & 2.7 using:
sudo update-alternatives --config python

Btw I installed node using ppa:chris-lea/node.js

I hope this helps somebody.

[Lujaw]

@laithshadeed Thanks, it solved the issue for me..

[scottkellie]

@laithshadeed Also repaired my build on Linux mint 16 :) Thanks was driving me crazy!
