It's really disgusting that this problem occurs. The reason is the compatibility issue with low version. I spent a whole morning trying to summarize the most practical method and record it here.
The first step is to uninstall sass-loader
npm uninstall sass-loader
If the uninstallation also reports an error, execute the following code
npm uninstall node-sass
npm uninstall sass-loader
The second step is to install a [email protected] and [email protected] version
npm install sass@1.26.5 --save-dev
npm install sass-loader@7.0.0 --save-dev
Finally, to install a lower version of sass-loader, you need to introduce node-sass dependency for support. Please execute the following code
npm install node-sass
ps It is best to use the installation environment that comes with VsCode
