尝试storybook使用Webpack@4.17.2and启动时出现此错误mini-css-extract-plugin。我正在使用mini-css-extract-plugin而不是extract-text-webpack-plugin因为它不支持Webpack > 4.x.x
任何想法如何在不降级到 webpack < 4.xx 错误的情况下解决此问题：
ERROR in ./src/styles/styles.less
Module build failed: TypeError: Cannot read property 'thisCompilation' of undefined
