我正在尝试使用以下代码：

@apply w-[calc(theme(width.1/3)_-_1rem)]根据文档，应该可以。但是每次我尝试编译代码时，都会出现以下错误：

Syntax Error: SyntaxError

<css input> 'width.1 / 3' does not exist in your theme config. 'width' has the following valid keys: '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '14', '16', '20', '24', '28', '32', '36', '40', '44', '48', '52', '56', '60', '64', '72', '80', '96', 'auto', 'px', '0.5', '1.5', '2.5', '3.5', '1/2', '1/3', '2/3', '1/4', '2/4', '3/4', '1/5', '2/5', '3/5', '4/5', '1/6', '2/6', '3/6', '4/6', '5/6', '1/12', '2/12', '3/12', '4/12', '5/12', '6/12', '7/12', '8/12', '9/12', '10/12', '11/12', 'full', 'screen', 'min', 'max', 'fit'

我感到困惑的是，我使用1/3密钥作为错误状态，但它似乎被解析为1 / 3我认为是我的问题？我正在使用带有 Roots Sage 9.0.10 的 Tailwind 3。

如果需要，这是我的package.json

似乎 Tailwind 无法即时从配置文件中获取值（在 JIT 模式下的方括号内）。我看到了在配置文件中注册自定义宽度类的选项，例如

// tailwind.config.js

module.exports = {
  theme: {
    extend: {
      width: {
        'custom': "calc( theme('width[1/3]') - 1rem)", // it is important to pass it as a string
      }
    },
  },
}

并像使用它一样

.selector {
  @apply w-custom;
}
