TypeError: dest.on不是gulp中的函数
TypeError: dest.on不是gulp中的函数
提问于 2019-01-25 07:53:52
当我在我的主题源文件夹中编辑主题.yml文件时，我得到这个错误。当我仅在主文件夹中编辑模板文件夹中的scss或模板.yml文件时，不会出现这种情况。其他有这个错误的人使用了像webpack这样的东西，这是我没有的。copy_theme_files的吞噬任务与其他任务相同，不同的是它没有返回，因为我不知道如何用两个gulp.src函数返回它。
gulp.task('copy_theme_files', function() {
console.log('[copy_theme_files] Console Log: copy '+paths.themeSrc+' to '+paths.themeDest);
gulp.src(paths.themeSrc)
.pipe(gulp.dest(paths.themeDest));
gulp.src(paths.root + '/*.{png,ico,svg}')
.pipe(paths.themeDest);
});Full gulpfile.js https://pastebin.com/NWt2uMwV
错误输出：

您的任务中包含以下内容：
.pipe(paths.themeDest);你的意思可能是：
.pipe(gulp.dest(paths.themeDest));对于你的另一个问题，请查看merging two gulp.src streams，了解如何返回：
var merge = require('merge-stream');
gulp.task('copy_theme_files', function() {
console.log('[copy_theme_files] Console Log: copy '+paths.themeSrc+' to '+paths.themeDest);
const themesStream = gulp.src(paths.themeSrc)
.pipe(gulp.dest(paths.themeDest));
const imagesStream = gulp.src(paths.root + '/*.{png,ico,svg}')
.pipe(paths.themeDest);
return merge(themesStream , imagesStream );
