title: Install heroku cli on linux *without* root, and *no auto update*
body: <p>I am a CS professor trying to teach web app development (Flask, Rails, SparkJava, etc.) using Heroku.</p>
  
  <p>Our computing environment is a centrally managed Linux system, where neither the students nor I, have root permission. The students also have a very limited file and disk quotas: 200MB of space, and 4000 individual files.</p>
  
  <p>I used to be able to provide them a way to give them access to the Heroku toolbelt by hacking the "standalone install" to get around the default assumption that the person doing the install has root permission.</p>
  
  <p>But it is no longer working. When I install into a directory and run from there, the Heroku toolbelt keeps trying to "auto-update" into the ~/.local/share for <em>each individual user</em>  and since the Heroku-CLI installation has over 12000 files in it (!) it blows their file quota.</p>
  
  <p>This is madness. I want to have just ONE installation of the Heroku toolbelt client, update it centrally and NOT have each student have to have their own copy. Is this too much to ask?  Is there any way to do this?</p>
  
  <p>There used to be some trick to making the client think it was already up-to-date or some way to configure it to NOT do the auto-update. But I can't find how to do it.</p>
  
  <p>(Thanks in advance for all of your good ideas such as: have them work on their own laptops, make a VM, have them work on AWS, etc. Those are all great ideas for some parallel universe in which they are feasible. If I <em>could</em> use any other computing environment, I'd already been doing that.  This is the one I have. If I can't make Heroku work here, I just can't use Heroku in class. And it's frustrating because it used to work.)</p>
