Cause of the problem

When the above error occurs, it is found that the version of SASS loader is too high, so the above problem occurs in the compilation

resolvent

We need to unload

cnpm uninstall less-loader

After reinstalling

cnpm i [email protected] --save-dev

Finally, it is compiled successfully
