this is part of my package.json:

"webpack": "^3.6.0",

The v4.0.0 of optimize-css-assets-webpack-plugin requires webpack v4.

@NMFR Many thanks, I have read your source code, and found the reason, so I changed optimize-css-assets-webpack-plugin to 3.2.0.

The v4.0.0 of optimize-css-assets-webpack-plugin requires webpack v4.

I see optimize-css-assets-webpack-plugin doesn't have a peerDependency on webpack at the moment. If one were added, it might prevent confusion for cases like this? :-)

[sayhitoarvind]

yeah I had this issue as well. Changed to 3.2.0 as Yugasun mentioned. Thanks

[NMFR]

peerDependency added, thanks for the suggestion @edmorley :)
