Heroku CLI install failing Mac OSX
<p>Randomly my heroku toolbelt stopped working. I'm not sure why, but when I execute any heroku action, for example <code>heroku -v</code> this happens:</p>

<pre><code>➜  Homebrew heroku -v
heroku-cli: Adding dependencies... 2.57 MB/2.57 MB
2016/04/26 12:13:42 running npm from /Users/cowan/.heroku: /Users/cowan/.heroku/node-5.10.1-darwin-amd64/node /Users/cowan/.heroku/npm-3.8.5/cli.js -v --loglevel=info
ERROR: expected npm  to equal v5.10.1
</code></pre>

<p>Note this particular example is after I used homebrew to uninstall and reinstall heroku. </p>
