You may not @extend an outer selector from within @media.

Hello,
I'm trying to build bootstrap-sass with sass-loader, and i'm getting the following error:

ERROR in ./~/css-loader!./~/sass-loader?outputStyle=expanded&includePaths[]=/Users/....../node_modules!./app/stylesheets/main.scss
Module build failed:
    .input-group-sm & {
                                     ^
      You may not @extend an outer selector from within @media.
You may only @extend selectors within the same directive.

Is this a known issue?

This is caused by a bug in libsass which has been solved in the latest 3.2 beta versions. Sass-loader v1.0.0 is bound to node-sass version 3.0.0-alpha, which provides the older libsass version containing this bug. See sass/libsass#943 for details.

@jtangelder, could you upgrade the node-sass dependency to the latest 3.0 beta version?

[jongbeau]

It's actually using the 3.0.0-beta.4 version of node-sass.

I've tested with the latest libsass version, but the problem remains indeed. I guess we have to keep an eye on the related issue twbs/bootstrap-sass#879.

For now I've created a workaround by adding a custom requirement to my package.json, which points to an older (working) version of node-sass:

...
"node-sass": "sass/node-sass#v3.0.0-pre",
...

@joostfarla the issue would be: sass/libsass#943 (as also linked in twbs/bootstrap-sass#879 (comment))
edit: just saw that you already mentioned that issue a few posts above. nevermind :-)

[jhnns]

Thx for the feedback, but this error does not seem to be related to sass-loader...

[Awem]

@jhnns that's correct. node-sass is already a peerDepency. Nothing more can be done.
