我是webpack的新手,我正在尝试将所有内容设置为反应项目 . 我已经设法让所有的东西都按照预期在webpack中工作,但是已经遇到了使用autoprefixer的路障 .
我已经关注了post css和autoprefixer的文档,我显然在这里缺少一些重要的东西,或者做了一些愚蠢的事情 . 请你看一下我的配置,如果你有任何建议,请告诉我 .
其他postcss插件工作得很好,像nanocss . 虽然我已经尝试了cssnext,因为我认为包括autoprefixer无论如何 .
我假设它是autoprefixer配置问题 .
如果您键入npx autoprefixer info,则在命令行中还有另一件事 . 一切都很好 . 我构建或运行开发服务器时没有错误它只是不自动修复任何东西 .
这是我的所有配置文件 . 提前致谢 .

module.exports = {

我现在也尝试过劳伦特的建议 . 我不确定这是否有进展但我现在收到一些错误记录 . 我的配置现在看起来像没有postcss.config

css.walkAtRules不是一个功能似乎是我的困境的来源但是 . 从配置的角度来看,一切似乎都很好 . 应该找到它 .
有任何想法吗?
谢谢!

我在同样的问题上挣扎并找到了解决方案 . 我也经历了应用autoprefixer的过程,该过程不起作用,也没有显示任何错误信息 .
我不知道我的解决方案是否可以解决您的问题,但让我们试一试 . 我试图转换scss代码,这基本上与转换更少代码的过程相同 .
我既没有定义postcss.config.js也没定义.browserlistrc文件 . 相反,在webpack.config.js中,我首先
然后,我在webpack.config.js中设置了以下配置(这里相当于更少):
据我所知,在大量的论坛中我找到了这条信息,因此加载顺序为'css-loader','postcss-loader',然后'less-loader'是至关重要的 . 在我的特定情况下,如果没有选项,它根本不起作用
希望这可以帮助...
我有同样的问题,我正确地修复它,但在我的配置中,我使用
PostCSS
与SCSS
样式 . 克隆并查看PostCSS configuration on Webpack,它是如此简单和正常工作 . 我不在这里写我的Webpack
配置,因为它很难阅读和使用 . 毫无疑问,我没有使用单独的PostCSS
配置文件 . 只需在Webpack
配置文件中编写PostCSS
配置 . 我更喜欢将Webpack
的开发和 生产环境 版本分开 . 看,如果有问题,请询问 . 我很乐意回答 .
