To solve the PostCSS problem go to node_nodules/@ionic/app-scripts/dist/sass.js and replace var postcssOptions = { to: path_1.basename(sassConfig.outFile), map: autoPrefixerMapOptions }; with var postcssOptions = { from: undefined, to: path_1.basename(sassConfig.outFile), map: autoPrefixerMapOptions };
