We are working on Predix Mobile SDK.So we are try to set Predix Mobile Development Environment for that we need set UAAC command line-utility .We flowed this link (https://github.com/cloudfoundry/cf-uaac). For Install we tried like this 

gem install cf-uaac

We got error this 

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/bin directory.

The cloud foundry cf-uaac cli tool is written in Ruby, so installation is done with gem, the ruby package manager.

You can run gem env from a terminal to find the installation directory for gems which is probably /usr/bin in your case. You wouldn't want to install your gems there as only root has permission to write. If you are on OSX there may even be more to the story.

I'm not sure what OS you are using so can't be too prescriptive, but a few suggestions for you can be found in this previous question to override this default behavior on your system:

  • Override install location on the commandline --user-install cf-uaac
  • Edit your ~/.gemrc to include something like this or change to one of the GEM PATHS
  • Re-install ruby to a different location where you do have write permission
  • Use ruby version manager rvm if you will be doing lots of ruby dev work and want to switch versions / gems

You can find out lots more about the install command in the rubygems guide if you were interested in learning more.

Hope that gets you going again.

  • This should probably be asked as a separate question, but that appears like the site is blocked. You may be behind a firewall and need to use a proxy. – j12y Sep 15 '16 at 14:19

UAAC is the Ruby-based command line interface (CLI) for interacting with the Cloud Foundry User Account and Authentication (UAA)

first install Ruby, you can follow the guidelines (steps 1 & 2) from here:

Ruby for Windows

then run this commend from powershell:

gem install cf-uaac

If you are behind a proxy you should add the source:

gem sources -a http://rubygems.org
