Hey everyone.
I want to try the Hamburger Menu and after adding it with yarn add i get a warning:
stylelint-webpack-plugin@0.10.5" has incorrect peer dependency “webpack@^1.13.2 || ^2.7.0 || ^3.11.0 || ^4.4.0”. My Mac was on yarn 1.7.0 and it was out of date. Ok.
So i run yarn start again to continue working, but the build process faild with an error:

ERROR  Failed to compile with 1 errors                                                                                                                                                             22:29:09

I removed the hamburger menu but the error is still there. After i updatet yarn from 1.7.0 to 1.9.4 but it did not help. I also update npm to npm@6.3.0 and i use stylelint-webpack-plugin@0.10.5.

When i do yarn build:production the error is still there:

I have not see such thing before & i searched on yarn and other sites for an answer, but i cant find anything. Do you have a tip for me?

I use sage 9.0.1 with bootstrap 4.1.0 on localhost (mac 10.13.3)

thank you in advance and please excuse my bad english

You’re using a variable before defining it $line-height-normal. Try swapping that for a normal value, or define it before using it.

Thanks bdmason, your are wright.
Strange was only that variable with a value existed and yet was not recognized. I had to rewrite and save it and it worked.

thanks again
