I have application bootstrapped from vue-cli with a webpack template. I\'m running it on Chrome 65.0.3325.146

Inside your webpack config file you can try to enable source map for your sass loader configuration.
You need to edit your file as follow:
module.exports = { css: { loaderOptions: { sass: { sourceMap: true } } } }
