一种解决方案：在 Illustrator 中，选择您的圆圈并选择Object> Compound Path> Make。

这是使用 Illustrator 圆形的快速测试，重复，第一个没有修改，第二个应用了复合路径：

<circle class="cls-1" cx="466.5" cy="184.5" r="117.5"/>
<path class="cls-1" d="M320,190.5A121.5,121.5,0,1,1,198.5,69,121.5,121.5,0,0,1,320,190.5Z" transform="translate(-77 -69)"/>

注意：Object您可以通过选择> Compound Path>恢复到基本形状Release。

一个测试用例：

在应用复合路径之前：

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 612 157.41935">
  <defs>
    <style>
      .a {
        fill: #ed2024;
      }

      .b {
        fill: none;
        stroke: #ed2024;
        stroke-miterlimit: 10;
        stroke-width: 40px;
      }
    </style>
  </defs>
  <title>before</title>
  <rect class="a" width="100" height="100"/>
  <rect class="a" x="127.54853" width="100" height="100" rx="12" ry="12"/>
  <circle class="a" cx="305.09706" cy="50" r="50"/>
  <polygon class="a" points="482.646 50 457.646 93.301 407.646 93.301 382.646 50 407.646 6.699 457.646 6.699 482.646 50"/>
  <polygon class="a" points="560.194 12.169 592.212 0.8 591.278 34.721 612 61.615 579.405 71.209 560.194 99.2 540.983 71.209 508.388 61.615 529.111 34.721 528.176 0.8 560.194 12.169"/>
  <line class="b" y1="137.41935" x2="612" y2="137.41935"/>
</svg>

将复合路径应用于每个单独的形状后：

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 612 157.41935">
  <defs>
    <style>
      .a {
        fill: #ed2024;
      }

      .b {
        fill: none;
        stroke: #ed2024;
        stroke-miterlimit: 10;
        stroke-width: 40px;
      }
    </style>
  </defs>
  <title>after</title>
  <path class="a" d="M100,100H0V0H100Z"/>
  <path class="a" d="M215.54853,100h-76a12.03528,12.03528,0,0,1-12-12V12a12.03528,12.03528,0,0,1,12-12h76a12.03528,12.03528,0,0,1,12,12V88A12.03528,12.03528,0,0,1,215.54853,100Z"/>
  <path class="a" d="M355.09706,50a50,50,0,1,1-50-50A50,50,0,0,1,355.09706,50Z"/>
  <path class="a" d="M482.6456,50l-25,43.30127h-50L382.6456,50l25-43.30127h50Z"/>

var circle = doc.getElementsByTagName('circle');

 var convertSvgCircleToPath = function(cx, cy, r, deg) {

      var theta = deg * Math.PI / 180,
      dx = r * Math.cos(theta),
      dy = -r * Math.sin(theta);

      return "M " + cx + " " + cy + "m " + dx + "," + dy + "a " + r + "," + r + " 0 1,0 " + -2 * dx + "," + -2 * dy + "a " + r + "," + r + " 0 1,0 " + 2 * dx + "," + 2 * dy;

 }

 convertSvgCircleToPath(circle.getAttribute('cx'), circle.getAttribute('cy'), circle.getAttribute('r'), 180);

cx = x 轴位置 cy = y 轴位置 r = 圆半径 deg = 180/360
