SASS npm 脚本问题（autoprefix 和 postcss）

Question

我的编译过程不工作，因为我是初学者，我不知道为什么。非常感谢任何建设性的帮助 ;)。

我花了大概 24 小时来解决这个问题，但没有成功... 我已经重新安装了所有软件包，清理了缓存等，但没有任何帮助。

  },

当我运行命令 npm 运行 prefix:css 我得到这样的错误：

npm run prefix:css

> postcss --use autoprefixer -b 'last ten versions' css/style.concat.css -o css/style.prefix.css

Error: PostCSS plugin autoprefixer requires PostCSS 8. Update PostCSS or downgrade this plugin.

我运行遇到了类似的问题 - autoprefixer version 10.0.0 似乎存在一些错误。

降级您的自动前缀版本，您的命令将运行符合预期。

将包文件中的 "autoprefixer": "^10.0.0", 更改为 "autoprefixer": "<10.0.0",。这将安装低于版本 10.0.0 的最新版本的 autoprefixer - reference.
