bcrypt make: execvp: g++ : not a directory - node.js

Question

I am trying to install bcrypt using npm on redHat, I have it working on my Windows dev environment but it fails when I try to port it to the Unix test.
I am running npm intall bcrypt and recieving the following output:
$ ../../nodejs/bin/npm install bcrypt
npm WARN package.json party#0.0.0 No repository field.
npm WARN package.json party#0.0.0 No README data

I have been Googling for hours, but cannot work out why this is failing - please help!

Answer 1

Okay, thanks, I have got this working, the version of GCC I was running did not include g++, unfortunately I do not have root on this box so had to install easybuild and then use that to install a new version of GCC, then include that version in the PATH, after that the npm install bcrypt worked perfectly.
