我正在使用Android Studio 3.1 Canary 6,我在构建项目时收到此错误.我搜索这个错误,许多用户得到这个有不同的原因,但我没有找到类似于我的问题.

在我的搜索中,我理解这个错误是由我们的代码中的错误引起的,比如语法错误,但在我的情况下,Android Studio没有显示错误,错误日志没有我的类.

我的build.gradle有:

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
       applicationId "my.app.id"
       minSdkVersion 21
       targetSdkVersion 27
       versionCode 1
       versionName '1.0.0'
       buildConfigField 'boolean', 'LOG_ENABLED', 'true'
    }
...
}

我认为是java/gradle代码的内部问题.记录错误:

我正在尝试将我的 webpack 项目与 sass-loader 集成，但出现此错误：

 Module build failed: Error: Cannot find module 'postcss'

我已经使用命令安装了 postcss 和 postcss-loader：

 npm install postcss postcss-loader --save-dev

安装后，我继续收到相同的错误消息。我测试仅将我的项目与 css-loader 集成，并且发生了同样的错误。我认为 postcss 是 css-loader 的依赖项。

在我的 webpack.config.js 中，我在 module.rules 中使用了这个配置：

 {
    test: /\.scss$/,
    use: [{
          loader: "style-loader" // creates style nodes from JS strings
      }, {
          loader: "css-loader" // translates CSS into CommonJS
      }, {
          loader: "sass-loader" // compiles Sass to CSS
      }
    ]
  }

我安装了所有这些加载器和 node-sass，我不知道我做错了什么:(
