Question

我正在使用gulp任务编译bootstrap-sass：

gulp.task('build-bootstrap-sass', function () {
  return gulp.src('styles/styles.sass')
    .pipe(sourcemaps.init())
    .pipe(sass({includePaths: ['node_modules/bootstrap-sass/assets/stylesheets/']}).on('error', sass.logError))
    .pipe(rename({basename:'bootstrap'}))
    .pipe(autoprefixer())
    .pipe(minifyCss())
    .pipe(sourcemaps.write('.'))
    .pipe(gulp.dest('dist/' ));
});

但是这给了我以下错误：

[09:32:38] Using gulpfile d:\Code\Templates\App\gulpfile.js
[09:32:38] Starting 'build-bootstrap-sass'...
d:\Code\Templates\App\node_modules\gulp-minify-css\node_modules\clean-css\lib\text\escape-store.js:49

问题似乎是在我使用源图时;如果我删除它，任务就会通过。但我正在使用所有gulp依赖项的“最新”版本;并且gulp-minify-css changelog表明它支持源映射＆lt; 1.1.6。当我使用sourcemaps而不缩小时，构建也会通过。

gulp-sourcemaps不支持gulp-minify-css。您可以在此处找到所有受支持的插件：https://github.com/floridoo/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support

您可以考虑使用gulp-cssnano来缩小css文件。
