Everything worked after I ran `brew update`.

Incase the brew update fails, try the following

    cd `brew --prefix`
    git remote add origin https://github.com/Homebrew/homebrew
    git fetch origin
    git reset --hard origin/master

I was having the same problem as Steve S regarding epstool dependency on Octave and found this link:

https://github.com/Homebrew/homebrew-science/issues/1110

Check out iml&#39;s post about 10 down from the top (his second post).  As he explained, I downloaded it from the fedoraproject.org site and then moved it into the /Library/Caches/Homebrew/ directory.

In my case the file downloaded from https://downloads.sourceforge.net/ctags/ctags-5.8.tar.gz is actually a html file. I downloaded the real file and place it at `/Library/Caches/Homebrew/ctags-5.8.tar.gz`. Then I run `brew install ctags`, everything works. 


This is my code so far:

    var n = 123456789;
    var d = n.toString().length;
    var digits = [];
    var squaredDigits = [];
    for (i = d; i &gt;= 1; i--) {
        var j = k / 10;
        var r = (n % k / j) - 0.5;
        var k = Math.pow(10, i);
        var result = r.toFixed(); 
        digits.push(result);
    }

    console.log(digits);

But when I run my code I get this: `[9, 1, 2, 3, 4, 5, 6, 7, 8]`

If anyone can see the problem or find a better solution I would very much appreciate it!


How do I separate an integer into separate digits in an array in JavaScript?

I&#39;m using [twitter-bootstrap][1], and i found it fairly hard to center `div` which has class `.btn-group` ([link][2]). 
Usually, I use 

    margin: 0 auto; 
    

or

    text-align: center;

to center stuff within div, but it doesn&#39;t work when inner element has property `float: left` which in this case uses for visual effects.

More specifically, I was using homebrew to install MySQL, and I got this error:

I want to do a `brew upgrade` and tell homebrew do not upgrade the `erlang` formula since the latest one does not work on my system.

Is it possible do do something like `homebrew upgrade --skip erlang`?

Ignore formula on brew upgrade

Trying to install ruby 1.9.3, read that I need to install homebrew first. Ran brew doctor, and it&#39;s giving me a bunch of warnings. One of which is:

&gt; Warning: /usr/bin occurs before /usr/local/bin This means that
&gt; system-provided programs will be used instead of those provided by
&gt; Homebrew. The following tools exist at both paths:
&gt; 
&gt;     easy_install
&gt;     easy_install-2.6
&gt; 
&gt; Consider amending your PATH so that /usr/local/bin is ahead of
&gt; /usr/bin in your PATH.

How does one do what it&#39;s asking here?

How to modify PATH for Homebrew?

I&#39;m very much a newbie when it comes to all this so forgive my incompetence.

When I run brew Doctor, I get the following. Can someone help?

&lt;!-- language: lang-bsh --&gt;

    [/usr/local]$ brew doctor

How do I fix brew doctor errors?

I tried to run `brew update` and I get an error about my local changes would be lost if I merged.  I tried committing my local changes (don&#39;t remember making any, but it&#39;s been awhile), and that made things worse.

brew update: The following untracked working tree files would be overwritten by merge:

I am getting issues with permissions in Homebrew: After I installed Node and tried to install npm using the curl command Homebrew tells you to use, it would fail due to EACCESS errors. I checked the node folder and the permissions were a) unowned by a user (I had to chown it) and b) Had no write permissions (I had to chmod 755 it).

I&#39;ve fixed the issue with NPM, but I had to run its install script as sudo (which is bad!).

I assume I must have installed Homebrew as root or something similar. I am hoping that reinstallation will fix it, but I can&#39;t find a source on how to reinstall Homebrew.

When I rerun the installer in Terminal I get:

    /usr/local/.git already exists!
