  </code></pre>
  <p>I reinstalled after I wrestled with trying to get RVM to work with Textmate and RVM behavior became strange (reporting it didn't have gemsets it would list) so I ran:</p>
  <pre><code>rvm implode
  </code></pre>
  <p>... and then manually removed the executable. Then I ran the install again by scrupulously following the <a href="https://rvm.beginrescueend.com/rvm/install/" rel="nofollow noreferrer">single user instructions from the home site.</a></p>
  <p>After I spotted the errors, I investigated the paths and found that many files in <code>~/.rvm/scripts/</code> and <code>~/.rvm/src/rvm/scripts/</code> which obviously should be executable did not have execute permissions.</p>
  <p>RVM would not run at all so I set the executable bit on all the files in the two directories and that seems to have fixed things. (So far at least.)</p>
  <p>Googling, it seems that other people have hit this problem but there seems to be no explanation or resolution. I would like to find out if this is a known issue and whether I should reinstall yet again.</p>
  <p>I'm running rvm 1.6.9 on MacOS X 10.6.7</p>
