即使我已经安装了postcss，当我试图编译时，我仍然会在终端中得到上面的错误。我将这个错误与tailwindcss一起使用，我的postcss.config.js文件看起来像这样：

module.exports = {
    plugins: [
        require('tailwindcss'),
        require('autoprefixer'),
        require('cssnano'),
    ]
}

我已经更新了我所有的包并清除了NPM缓存。我的其他版本都没有发生这种情况。我的package.json文件中是否有错误？以下是其中的一部分：
