【问题描述】：
我一直在尝试构建我之前构建良好的代码的生产版本。现在，当我在 main.js 文件上运行 vue build 时，它提供了以下内容：
\ Building for production...Browserslist: caniuse-lite is outdated. Please run next command `npm update caniuse-lite browserslist`
\ Building for production...Browserslist: caniuse-lite is outdated. Please run next command `npm update caniuse-lite browserslist`
Browserslist: caniuse-lite is outdated. Please run next command `npm update caniuse-lite browserslist`
\ Building for production...Browserslist: caniuse-lite is outdated. Please run next command `npm update caniuse-lite browserslist`
(node:10708) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: CSS minification error: Unknown browser query `basedir=$(dirname "$(echo "$0" | sed -e 's`. Maybe you are using old Browserslist or made typo in query.. File: css/app.75eb53b0.css
(node:10708) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
我已尝试通过手动更新包和依赖于它的包、启动新项目、运行npm --depth 999 命令（深度 9999 导致内存堆错误）来解决 Browserslist/caniuse-lite 错误，以及我能找到的所有其他事情。我没有使用 VS（使用 VS 代码），但试图通过从我的 AppData 中删除 WebCompiler 信息来解决问题，但没有 WebCompiler 文件夹开始。
我还尝试恢复到 css-loader 2.1.1，这解决了在处理此问题时出现的另一个问题，但尚未解决此问题。
任何帮助将不胜感激，因为这会阻止任何更新发布到生产。
我已尝试在其他线程中修复有关 Browserslist 警告的问题。此外，这些线程没有提到以下错误：
(node:10708) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: CSS minification error: Unknown browser query `basedir=$(dirname "$(echo "$0" | sed -e 's`. Maybe you are using old Browserslist or made typo in query.. File: css/app.75eb53b0.css

谢谢，但是“C:\Users\USERNAME\AppData\Local\Temp\WebCompilerX.X.X”对我来说不存在

可能，虽然我已经尝试了该线程中的所有修复，但它没有提到
