sassのコンパイル時にどうにもgulp-combine-media-queriesがエラーを起こしてしまって、けっこうハマってしまった。

環境

node: v4.2.2
npm: 2.14.7
gulp: CLI version 3.9.0
gulp: Local version 3.9.0
gulp-combine-media-queries: 3.1.0

エラー内容

内容は以下のような感じ。

buffer.js:167
  throw new TypeError('must start with number, buffer, array or string');
  ^

解決策

gulp-combine-media-queries/index.jsの152目の以下の箇所がエラーになるので、コメントアウトすればひとまずは解決できた。

file.contents = new Buffer(cssJson);

issuesに上がっているので、おそらくいずれ解決されるはず。。
doesn’t work with last version sass #19
