Following instructions from README, npm install fails with Failed at the runtimejs@0.2.14 postinstall script 'node scripts/update-versions.js':

Env:

# npm -v

Output:

root@ubuntu:~/runtime.js/helloworld# npm install

Is the latest runtime.js version (0.2.14) stable? Looked through open/closed issues, but could not find above symptom being encountered before. If 0.2.14 is not stable, can you please recommend a stable version to try out? Thanks a lot!
