javascript - 类型错误 : Cannot read property 'pipe' of undefined gulpjs

Question

我正在尝试设置 gulp-spritesmith，每次在图标文件夹中粘贴某些内容时都会出现上述错误。还尝试让它在 mac 上通过 sass.Node 版本 2.14.12 进行编译。如果有任何其他更易于使用的“sprite”插件，请告知。

参见https://github.com/twolfson/gulp.spritesmith#breaking-changes-in-600

根据该链接上的文档，在 spritesmith 版本 6 中，如果您的图像管道需要缓冲内容而不是流，您可能需要使用乙烯基，例如

var buffer = require('vinyl-buffer');
spriteData.img.pipe(buffer()).pipe(imagemin());
