Gulp手表错误与gulp pug

Question

我试图设置我的gulp来观察pug的变化，但我得到了以下错误，我不知道这会是什么：

events.js:141
      throw er; // Unhandled 'error' event
      ^
SyntaxError: Unexpected token (19:0)
    at Parser.pp$4.raise (/../node_modules/acorn/dist/acorn.js:2221:15)

    at Parser.pp$1.parseVarStatement (/../node_modules/acorn/dist/acorn.js:917:10)

我的gulpfile.js看起来像这样：

const gulp = require('gulp');
const pug = require('gulp-pug');    

gulp.task('pug', () =>
  gulp.src('pug/*.pug')
    .pipe(pug({ pretty: false }))
    .pipe(gulp.dest('.'))    
);

gulp.task('watch', function (){
  gulp.watch('pug/*.pug', ['pug']);
});

Answer 1

问题可能是.pipe(gulp.dest('.'))，您应该指定一个实际的文件夹名称。例如.pipe(gulp.dest('folderName')) / .pipe(gulp.dest([__dirname])

此外，向gulp.src('pug/*.pug')添加一条return语句，使其如下所示

通过包含return语句，return gulp.src('pug/*.pug')避免了错误。

您可以编辑您的问题，包括您的Pug文件，请？
