tailwindcss not applied after building package with tsdx

I'm not sure if this is a bug. I've got a tsdx uikit project with tailwindcss 3.2.6 "postcss": "^8.4.14" and "autoprefixer": "^10.4.13". I also have storybook in my project. The problem is that all tailwind classes are working alright in storybook but after I build the package and install it on another project none are working. I also got this tsdx.config.js with inject:true:

const postcss = require('rollup-plugin-postcss');
const autoprefixer = require('autoprefixer');
const cssnano = require('cssnano');
const tailwindcss = require('tailwindcss');
let static_files = require('rollup-plugin-static-files');

module.exports = {
  rollup(config, options) {
    config.plugins.push(
      static_files({
        include: ['./src/assets', './src/styles'],
      }),
      postcss({
        plugins: [
          tailwindcss({
            purge: ['./src/**/*.tsx'],
            darkMode: false, // or 'media' or 'class'
            theme: {
              extend: {},
            },
            variants: {
              extend: {},
            },
            plugins: [],
          }),
          autoprefixer(),
        ],
        inject: true,
        // only write out CSS for the first bundle (avoids pointless extra files):
        extract: !!options.writeMeta,
      })
    );
    return config;
  },
};

Also when I build the project the components files are like this. for example for badge component there is a index.d.ts with following code:

import React, { FC } from "react";
import { colorsTypes } from "../../../types/colors-types";
declare type size = "lg" | "md" | "sm" | "xs";
export interface BadgeProps {
    size?: size;
    color?: colorsTypes;
    bgColor?: colorsTypes;
    className?: string;
    rounded?: string;
    children?: React.ReactNode;
    badgeContent?: React.ReactNode;
}
export declare const Badge: FC<BadgeProps>;
export default Badge;

while I have more codes in my src using tailwind classes. I just can't find what's wrong.
