Javascript 对IE11的Nuxt和Vue支持

在Vue和Nuxt中实现的应用程序中支持IE11有问题。该应用程序使用Tailwind CSS库

我用创建了polyfill，但没有解决问题。我对它进行了更多的调查，发现node_模块的源代码没有传输到ES5标准（尤其是与Tailwind库相关的代码）。我尝试了几种解决办法，但都没有解决我的问题。我将transfile属性添加到nuxt.config.js，但添加后出现错误：

无法分配给对象“#”的只读属性“exports”

。我还尝试添加@nuxt/babel预设应用程序，但也没有帮助我

我当前发行的图片：

这是我的nuxt.config.js：

这是使用ESM和CJS时最常见的错误：

答复：

我认为您不应该像在配置中那样

require

postss插件。见文件：

我建议你改用这个。因此，您不必担心设置。它还添加了

numxt purgecss

模块

你找到解决办法了吗？我遇到了IE11到的问题，可能需要大力支持
