Errors when using with sass-loader

まず、issue に示されている設定を使用して、報告された Windows webpack --watch コマンドを sass-loader と sass-embedded で再現します。次に、参照されている runtime/bin/eventhandler_win.cc の場所を調査し、繰り返し発生する read-file-thread エラーが embedded Sass プロセスに起因するのか、その統合に起因するのかを特定します。原因が特定され、Windows の watch ビルドでこれらのエラーが発生しなくなれば完了です。

Hello,

I have a pretty large codebase to compile and I was trying sass-embedded.
When I am running webpack with the following config:

					{
						loader: 'sass-loader',
						options: {
							sassOptions: {
								sourceMap: true,
								includePaths: [path.resolve(__dirname, 'Develop', 'Styles'), path.resolve(__dirname, 'WebComponents')],
							},
							implementation: require('sass-embedded')
						}
					}

Dart errors with the following error:

> webpack --config webpack.configs.dev.js --watch

It looks like evenhandler_win.cc is a dart file.
