引导程序更改 $grid-gutter-width

我正在使用 Bootstraps 网格系统，我需要一个2px每列之间的空间。我尝试过 Column-Gap 但没有任何效果。

有人可以帮忙吗？

代码 HTML：

<div class="container">
<div class="row">
<div class="col-md-3" id="one">
<h3>Pink</h3>

</div>
<div class="col-md-3" id="two">
<h3>Purple</h3>
</div>
<div class="col-md-3" id="three">
<h3>Green</h3>
</div>
<div class="col-md-3" id="four">
<h3>Orange</h3>
</div>
</div>
<div class="row2">
<div class="col-md-3" >
<h3>Things that are Pink</h3>
<p>Pigs</p>
<p>Barbie</p>
<p>Some Skins</p>
<p>Ham</p>
</div>
<div class="col-md-3" >
<h3>Things that are Purple</h3>
<p>Prince</p>
<p>Goths</p>
<p>Paint</p>
<p>Berries</p>
</div>
<div class="col-md-3" >
<h3>Things that are Green</h3>
<p>Grass</p>
<p>Peas</p>
<p>Leafs</p>
<p>Apple</p>
</div>
<div class="col-md-3" >
<h3>Things that are Orange</h3>
<p>Orange</p>
<p>Ice-Lolly</p>
<p>Essex</p>
<p>Carrots</p>
</div>
</div>
</div>
</body>
</html>

body {
font-family: 'Roboto Mono', monospace;
