The supported version seems to be `^3.1.0`, while the current one is `5.1.0`, which fails on this line:\r\n\r\n```js\r\nbrowsers = autoprefixer.prefixes.browsers;\r\n```\r\n\r\nbecause `browsers` are now located in `autoprefixer.data.browsers` (I haven't actually tested that, though). The solution would maybe be to add `autoprefixer@3.1.0` as a dependency of this package?"},"comment":{"url":"https://api.github.com/repos/assetgraph/assetgraph-builder/issues/comments/91146258","html_url":"https://github.com/assetgraph/assetgraph-builder/issues/168#issuecomment-91146258","issue_url":"https://api.github.com/repos/assetgraph/assetgraph-builder/issues/168","id":91146258,"user":{"login":"Munter","id":331790,"avatar_url":"https://avatars.githubusercontent.com/u/331790?v=3","gravatar_id":"","url":"https://api.github.com/users/Munter","html_url":"https://github.com/Munter","followers_url":"https://api.github.com/users/Munter/followers","following_url":"https://api.github.com/users/Munter/following{/other_user}","gists_url":"https://api.github.com/users/Munter/gists{/gist_id}","starred_url":"https://api.github.com/users/Munter/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Munter/subscriptions","organizations_url":"https://api.github.com/users/Munter/orgs","repos_url":"https://api.github.com/users/Munter/repos","events_url":"https://api.github.com/users/Munter/events{/privacy}","received_events_url":"https://api.github.com/users/Munter/received_events","type":"User","site_admin":false},"created_at":"2015-04-09T08:13:58Z","updated_at":"2015-04-09T08:13:58Z","body":"For all sort of external compilers we want to have the installation optional and let people install the version they need.
