vue-loader v15版本打包时在::v-deep { ... } 中写多行注释时webpack5编译时会报 Module build failed (from . /node modules/@vue/vue-loader-v15/lib/loaders/stylePostLoader.js):; TypeError: Cannot read properties of undefined (reading 'spaces") at /users/xxx/xxx/example.scss:15:1错误

// for example, file name is demo.scss
::v-deep {
/* 多行注释 */
.some-class-name {
color: red;
}
}
当你将这个多行注释改为单行注释则编译通过不报错
