我遇到了问题gulp
。我和 和gulp-watch
一起跑。一切都在完美运行。gulp-less
gulp-clean
当我编辑somefile.less
并保存它时缺少分号,或者我可能不小心留下了尾随;s
,保存时我的代码中出现gulp-less
错误,在控制台中记录错误。修复后,它会gulp-watch
继续查看文件,但gulp-less
不会触发且无法编译。当我停止gulp
并在终端中再次运行它时,一切都恢复正常。
这是我的gulpfile.js
:
var gulp = require('gulp');
var clean = require('gulp-clean');
var gutil = require('gulp-util');
var less = require('gulp-less');
var watch = require('gulp-watch');
var path = require('path');
gulp.task('clean', function() {
return gulp.src('src/main/webapp/styles/build', {read: false})
.pipe(clean().on('error', gutil.log))
});
gulp.task('less', function() {
return gulp.src(['src/main/webapp/styles/main.less'], {base: 'src/main/webapp/styles/'})
.pipe(less().on('error', gutil.log))
.pipe(gulp.dest('src/main/webapp/styles/build'))
.on('error', gutil.log);
});
gulp.task('watch', function() {
watch('src/main/webapp/styles/**/*.{less, css}', function() {
gulp.start('less')
.on('error', gutil.log);
})
});
gulp.task('default', ['clean'], function() {
gulp.start(['less', 'watch'])
.on('error', gutil.log);
});
这是我的devDependencies
:
"devDependencies": {
"gulp": "^3.8.10",
"gulp-clean": "^0.3.1",
"gulp-less": "^2.0.1",
"gulp-util": "^3.0.2",
"gulp-watch": "^3.0.0"
}
最后,这是控制台中的消息:
[10:21:03] imports/productSearchPage.less was changed
[10:21:03] Starting 'less'...
[10:21:03] { [Error: Unrecognised input. Possibly missing something in file /src/main/webapp/styles/imports/productSearchPage.less line no. 1008]

^C
您能否告诉我该gulp-watch
任务有什么问题,并帮助我在删除错误后使其运行gulp-less
,而无需重新启动gulp
。
编辑:我编辑的gulp-less
任务
gulp.task('less', function() {
return gulp.src(['src/main/webapp/styles/main.less'], {base: 'src/main/webapp/styles/'})
.pipe(less().on('error', gutil.log))
.pipe(gulp.dest('src/main/webapp/styles/build'))
.on('error', function(err) {
gutil.log(err);
this.emit('end');
});
});
