我在使用gulp
时遇到了问题。我运行gulp-watch
以及gulp-less
和gulp-clean
,一切都运行得很好。
当我编辑somefile.less
并保存时,如果缺少分号或者误留下尾部的;s
等错误,gulp-less
会在控制台中记录一个错误。修复后,gulp-watch
继续监视文件,但gulp-less
不再触发,也不进行编译。当我停止gulp
并在终端中重新运行时,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);
});
以下是我的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
请告诉我gulp-watch
任务出了什么问题,并帮助我在错误被修复后运行gulp-less
,而无需重新启动gulp
。
编辑:
我的已编辑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');
});
});
