javascript - 错误 : PostCSS plugin tailwindcss requires PostCSS 8

Question

我安装了新的 tailwindcss 2.0 版，但出现以下错误。我试图卸载 postcss 和 tailwindcss 但它不起作用。需要帮忙。

Module build failed (from ./node_modules/postcss-loader/src/index.js):
Error: PostCSS plugin tailwindcss requires PostCSS 8.

您正在将 Tailwind 与依赖于旧版 PostCSS 的工具集成。您可以使用此文档 https://tailwindcss.com/docs/installation#post-css-7-compatibility-build
