gulp-观看无休止的编译而不对文件进行更改

Question

出于某种原因，我的脚本 gulp-watch 任务无休止地循环运行（以至于它激活了我的 MBP 上的风扇！），尽管我使用的是相同的 gulp 文件在其他各种项目中。

它只是一遍又一遍地编译脚本。尝试删除所有节点模块并再次使用 npm install。但同样的问题。我设置的 sass 编译任务没有同样的问题。

我什至尝试排除编译供应商代码，如 jquery/其他插件。 gulp.watch(['./js/*.js', '!./js/vendor/**'], ['scripts']);

但仍然有同样的问题。

也试着把一些脚本注释掉，然后一一重新介绍。但是似乎没有一个一致的违规脚本。

// include gulp
var gulp = require('gulp'); 


// --------------------------------------------------------------
// Plugins
// ---------------------------------------------------------------

var concat = require('gulp-concat');
var stripDebug = require('gulp-strip-debug');
var uglify = require('gulp-uglify');
var include = require('gulp-include');
var sass = require('gulp-sass');
var minifycss = require('gulp-minify-css');
var watch = require('gulp-watch');
var livereload = require('gulp-livereload');
var changed = require('gulp-changed');


// --------------------------------------------------------------
// JS
// ---------------------------------------------------------------

gulp.task('scripts', function() {
gulp.src(['./js/script.js'])
    .pipe(include())
    .pipe(concat('script-dist.js'))
    .pipe(stripDebug())
    .pipe(uglify())
    .pipe(gulp.dest('./js/'))
    .pipe(livereload());
 });

// --------------------------------------------------------------
// Sass
// ---------------------------------------------------------------

gulp.task('styles', function() {
gulp.src('./ui/scss/styles.scss')
    .pipe(include())
    .pipe(sass({
        errLogToConsole: true
    }))
    .pipe(minifycss())
    .pipe(gulp.dest('./ui/css/'))
    .pipe(livereload());
});

gulp.task('watch', function() {

gulp.watch('./ui/scss/*.scss', ['styles']);
gulp.watch('./js/*.js', ['scripts']);});

gulp.task('default', ['styles', 'watch']);
gulp.task('default', ['scripts', 'watch']);

livereload.listen();

终端输出（路径替换为'PATH'）：

您正在观看 js 文件夹中的 *.js 个文件，然后是运行 scripts 任务。

gulp.watch('./js/*.js', ['scripts']);});

您的 scripts 任务是将 .js 文件写入 js 文件夹

.pipe(gulp.dest('./js/'))

...然后再次触发监视条件....您现在有一个循环。
