Update to Node v4.0

[shinglyu]

Currently the GIJ fails because it needs node 4.0. Need to update and test it.

Cool, thanks for fixing this.

Hi Shing, I tried to change this to get it working:
--- a/scripts/gij.sh
+++ b/scripts/gij.sh
@@ -11,8 +11,8 @@ sudo apt-get update
sudo apt-get install -y build-essential libssl-dev pcregrep
curl -o- https://raw.githubusercontent.com/creationix/nvm/$NVM_VER/install.sh | bash #Notice the version may change
source ~/.nvm/nvm.sh
-nvm install 0.12
-nvm use 0.12
+nvm install 4.2
+nvm use 4.2

But I still get the error message:
Please use v4.2 of nodejs or it may cause unexpected error.
Minimum required version of nodejs v4 not satisfied. Aborting. Install the required minimum version before continuing.

Do you know what needs to be changed?

Oh my. I think we might have to talk to Aus, otherwise we might need to fix the gaia version.

I tried to upgrade to node 4.2, the error message goes away, but the make test-integration command fails because of the sockit-to-me package. I'm looking into it.

@shinglyu How did you upgrade to 4.2? What do I need to do to be able to do that?

@mwargers Just change the nvm commad like this: f311626#diff-248114233d816323c4805083571f930fR15

It turns out that we need to install clang, closed by bc231c7
