gruntjs - grunt-contrib-cssmin missing _stream_transform module -

i next error when trying run css minification gruntjs , have no clue why.

loading "cssmin.js" tasks...error >> error: cannot find module '_stream_transform

what origin of error message? i've search through cssmin.js file , can't find single reference module.

i've same problem. go grunt-contrib-cssmin/node_modules/maxmin/node_modules/gzip-size/node_modules/browserify-zlib , install readable-stream module

npm install readable-stream

then modify file grunt-contrib-cssmin/node_modules/maxmin/node_modules/gzip-size/node_modules/browserify-zlib/src/index.js

replace:

var transform = require('_stream_transform');

by:

var transform = require('readable-stream').transform;

it works me , hope help you.
