如何解决生产环境中的Sass-loader问题
我将Rails用作后端，将vue.js用作前端。 每当我尝试在生产环境中构建映像时，它都会失败并引发错误。找不到模块：错误：无法解析“ sass-loader”
警告“> vue-loader@15.9.3”具有未满足的对等依赖项“ css-loader @ *”。
警告“> vue-loader@15.9.3”具有未满足的对等项依赖性“ webpack@^3.0.0 || ^ 4.1.0 || ^ 5.0.0-0”。
警告“> sass-loader@9.0.3”具有未满足的对等依赖项“ webpack@^4.36.0 || ^ 5.0.0”。
警告“> webpack-dev-server@3.11.0”具有未满足的对等依赖项“ webpack@^4.0.0 || ^ 5.0.0”。
警告“ webpack-dev-server> webpack-dev-middleware@3.7.2”具有未满足的对等依赖项“ webpack@^4.0.0”。
我的日志文件是这样的： 有人可以帮忙吗？
