我的渐变有问题，但是这里出了什么问题，我该如何缓解这个问题？

我在使用 compass 0.12.7 的项目中遇到了同样的问题，不幸的是，这个问题只能通过更新 compass 来解决。linear-gradient使用位置值to right类似于以下示例中的 mixin 时会导致问题警告：

div {
  @include background(linear-gradient(to right, red, blue));
}

这将被编译成这样的东西（在你的问题中抛出错误）：

div {
  background: -webkit-gradient(linear, to right, to left, color-stop(0%, #ff0000), color-stop(100%, #0000ff));
  background: -webkit-linear-gradient(to right, #ff0000, #0000ff);
  background: -moz-linear-gradient(to right, #ff0000, #0000ff);
  background: -o-linear-gradient(to right, #ff0000, #0000ff);
  background: linear-gradient(to right, #ff0000, #0000ff);
}

不幸的是，这是无效的 CSS 代码。正确的输出应该如下：

div {
  background: -webkit-gradient(linear, 0% 50%, 100% 50%, color-stop(0%, #ff0000), color-stop(100%, #0000ff));
  background: -moz-linear-gradient(left, #ff0000, #0000ff);
  background: -webkit-linear-gradient(left, #ff0000, #0000ff);
  background: linear-gradient(to right, #ff0000, #0000ff);
}

正如我之前所说，修复它的唯一方法是更新指南针。

如果你不能/不想更新你的 sass，你可以删除那个“to”属性。

默认的 sass 渐变是垂直的：

@include background(linear-gradient(red, blue));

要获得水平：

@include background(linear-gradient(90deg, red, blue));
