发现无效的 PostCSS 插件：[0]

Question

几天来我一直在努力让我的 Spring 引导应用程序再次运行...

我想将我的应用程序部署到 Heroku，但我遇到了一个非常奇怪的错误：

Uncaught Error: Module build failed: TypeError: Invalid PostCSS Plugin found: [0]

我用谷歌搜索，发现我的绑定可能不正确。所以我执行了

npm rebuild node-sass --force

以便正确设置它们。但这没有帮助。从那时起我就收到了这个错误。

我还发现它与我的 postcss.config.js 有关的提示，它是空的（现在已经这样工作了 6 周）。所以我添加了一些插件。现在看起来像这样：

module.exports = {
  parser: require('postcss-scss'),
  plugins: [
        require('postcss-sassy-mixins'),
        require('precss'),
        require('autoprefixer')
    ]
}

这也没有帮助。它仍然向我显示存在无效 postcss 插件的错误。（postcss.conig.js 中的所有插件都是通过 npm 安装的）。

请在此处查看我的package.json：

Answer 1

所以现在我又遇到了这个错误，想确认 Dan Cancro 的回答是否成功！

这正是我所做的（为了其他人不要像我一样浪费那么多时间）：

我把"postcss-loader": "1.3.0" 改成 "postcss-loader": "1.3.3"
已删除 /node_modules 文件夹
删除了包-lock.json文件
运行 npm install
运行 纱线运行 webpack:build

这解决了我的问题。
