To install it, you can run: npm install --save -!../…/node_modules/@vue/cli-service/node_modules/css-loader/dist/cjs.js??ref–6-oneOf-1-1!../…/node_modules/vue-loader-v16/dist/stylePostLoader.js!../…/node_modules/postcss-loader/src/index.js??ref–6-oneOf-1-2!../assest/css/login-in.css

遇到相似的报错，一般是错误引入文件问题，在上面已经标识出来了。
上面的问题是说，在 /src/views/LoginIn.vue 文件下引入了 ./assest/css/login-in.css 发生错误。看看引入文件路径是不是写错了。
