angular-devkit/build-angular版本0.13.4 - configuration.output具有未知属性'futureEmitAssets‘

Question

我刚刚将一个项目从angular-devkit/build-angular v0.11.4升级到v0.13.4。我现在收到以下错误：

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.output has an unknown property 'futureEmitAssets'. 
These properties are valid:
   object { auxiliaryComment?, chunkCallbackName?, chunkFilename?, chunkLoadTimeout?, crossOriginLoading?, devtoolFallbackModuleFilenameTemplate?, devtoolLineToLine?, devtoolModuleFilenameTemplate?, devtoolNamespace?, filename?, globalObject?, hashDigest?, hashDigestLength?, hashFunction?, hashSalt?, hotUpdateChunkFilename?, hotUpdateFunction?, hotUpdateMainFilename?, jsonpFunction?, jsonpScriptType?, library?, libraryExport?, libraryTarget?, path?, pathinfo?, publicPath?, sourceMapFilename?, sourcePrefix?, strictModuleExceptionHandling?, umdNamedDefine?, webassemblyModuleFilename? }
   -> Options affecting the output of the compilation. `output` options tell webpack how to write the compiled files to disk.

          }
        }
      }
    }
  },
  "defaultProject": "ui"
}

我的启动命令是ng serve --proxy-config proxy.config.js

我在代码中找不到任何futureEmitAssets实例。有谁有什么想法吗？

你需要webpack@4.29或更高版本来解决这个问题。
