<h2>EDIT:</h2>
It looks like <a href="https://github.com/mxcl/homebrew/issues/7465#issuecomment-4998005" rel="noreferrer">the issue is now solved using an external command called <code>brew rmdeps</code> or <code>brew rmtree</code></a>.
To install and use, issue the following commands:
<pre><code>$ brew tap beeftornado/rmtree
$ brew rmtree &lt;package&gt;
</code></pre>
See the above link for more information and discussion.
<hr />
[EDIT] see the new command <code>brew autoremove</code> in <a href="https://stackoverflow.com/a/66719581/160968">https://stackoverflow.com/a/66719581/160968</a>
<hr />
<h2>Original answer:</h2>
It appears that currently, there's no easy way to accomplish this.
However, I <a href="https://github.com/mxcl/homebrew/issues/7465" rel="noreferrer">filed an issue on Homebrew's GitHub page</a>, and somebody suggested a temporary solution until they add an exclusive command to solve this.
There's an <a href="https://github.com/mxcl/homebrew/wiki/External-Commands" rel="noreferrer">external command</a> called <code>brew leaves</code> which prints all packages that are not dependencies of other packages.
If you do a logical and on the output of <code>brew leaves</code> and <code>brew deps &lt;package&gt;</code>, you might just get a list of the orphaned dependency packages, which you can uninstall manually afterwards. Combine this with <code>xargs</code> and you'll get what you need, I guess (untested, don't count on this).
<hr />
EDIT: Somebody just suggested a very similar solution, using <code>join</code> instead of <code>xargs</code>:
<pre><code>brew rm FORMULA
brew rm $(join &lt;(brew leaves) &lt;(brew deps FORMULA))
</code></pre>
<hr />
See the <a href="https://github.com/mxcl/homebrew/issues/7465#issuecomment-2027137" rel="noreferrer">comment on the issue mentioned above</a> for more info.

Using this answer requires that you create and maintain a file that contains the package names you want installed on your system. If you don't have one already, use the following command and delete the package names what you don't want to keep installed.

<pre><code>brew leaves &gt; brew_packages
</code></pre>

Then you can remove all installed, but unwanted packages and any unnecessary dependencies by running the following command

<pre><code>brew_clean brew_packages
</code></pre>

<code>brew_clean</code> is available here: <a href="https://gist.github.com/cskeeters/10ff1295bca93808213d">https://gist.github.com/cskeeters/10ff1295bca93808213d</a>

This script gets all of the packages you specified in brew_packages and all of their dependancies and compares them against the output of <code>brew list</code> and finally removes the unwanted packages after verifying this list with the user.

At this point if you want to remove package <code>a</code>, you simply remove it from the brew_packages file then re-run <code>brew_clean brew_packages</code>. It will remove <code>b</code>, but not <code>c</code>.

Based on @jfmercer answer (corrections needed more than a comment).

Remove package's dependencies (does not remove package):

<pre><code>brew deps [FORMULA] | xargs brew remove --ignore-dependencies

Remove package:

<pre><code>brew remove [FORMULA]

Reinstall missing libraries:

<pre><code>brew missing | cut -d: -f2 | sort | uniq | xargs brew install

<h2>A More-Complete Bourne Shell Function</h2>

There are a number of good answers already, but some are out of date and none of them are entirely complete. In particular, most of them will remove dependencies but still leave it up to you to remove the originally-targeted formula afterwards. The posted one-liners can also be tedious to work with if you want to uninstall more than one formula at a time.

Here is a Bourne-compatible shell function (without any known Bashisms) that takes a list of formulae, removes each one's dependencies, removes all copies of the formula itself, and then reinstalls any missing dependencies.

<pre><code>unbrew () {
 local formula
 for formula in "$@"; do
 brew deps "$formula" |
 xargs brew uninstall --ignore-dependencies --force
 brew uninstall --force "$formula"
 done
 brew missing | cut -f2 -d: | sort -u | xargs brew install
}
</code></pre>

It was tested on Homebrew 1.7.4.

<h2>Caveats</h2>

This works on all standard formulae that I tested. It does not presently handle casks, but neither will it complain loudly if you attempt to unbrew a cask with the same name as a standard formula (e.g. MacVim).

By the end of 2020, the Homebrew team added a simple command <code>brew autoremove</code> to remove all unused dependencies.
First, uninstall the package:
<code>brew uninstall &lt;package&gt;</code>
Then, remove all the unused dependencies:
<code>brew autoremove</code>

I have a Homebrew formula that I wish to uninstall/remove along with all its dependencies, skipping packages whom other packages depend upon (a.k.a. <a href="https://en.wikipedia.org/wiki/Package_manager#Cascading_package_removal" rel="noreferrer">Cascading package removal</a> in Package manager parlance).

e.g. Uninstall package <code>a</code> which depends on packages <code>b</code> &amp; <code>c</code>, where package <code>d</code> also depends on package <code>c</code>. The result should uninstall both <code>a</code> &amp; <code>b</code>, skipping <code>c</code>.

How can I do that?

There must be a way to uninstall a package without leaving unnecessary junk behind.

我有一个Homebrew公式，我希望卸载/删除它的所有依赖项，跳过其他包依赖的包(也称为包管理器术语中的 )。例如，卸载依赖于软件包b和c的package a，其中package d也依赖于package c。结果应该会卸载a和b，跳过c。我该怎么做呢？必须有一种方法来卸载一个包，而不会留下不必要的垃圾。
