javascript - 错误 : Missing positive glob

Question

每次 gulp 进入“标记”功能时都会出现上述消息。

这是我的 gulpfile:

var gulp = require('gulp'),
    autoPrefixer = require('gulp-autoprefixer'),
    jade = require('gulp-jade'),
    liveReload = require('gulp-livereload'),
    sourceMaps = require('gulp-sourcemaps'),
    ts = require('gulp-typescript'),
    tsLint = require('gulp-tslint'),
    watch = require('gulp-watch'),
    sass = require('gulp-sass');

// Configuration
var config = {
    js: 'public/_assets/frontend/js',
    css: 'public/_assets/frontend/css',
    fonts: 'public/_assets/frontend/fonts',
    images: 'public/_assets/frontend/img',
    markup: 'public/'
};

// Javascript
gulp.task('scripts', function() {
    var tsResult = gulp.src(['src/ts/*.ts', 'src/ts/**/*.ts'])
        .pipe(tsLint())
        .pipe(ts({
            noImplicitAny: true
        }));

        tsResult.js
            .pipe(gulp.dest(config.js))
            .pipe(liveReload());
});

// Sass
gulp.task('sass', function() {
    return gulp.src(['src/sass/*.scss', 'src/sass/**/*.scss'])
        .pipe(watch(['src/sass/*.scss', 'src/sass/**/*.scss']))
        .pipe(sourceMaps.init())
        .pipe(sass.sync().on('error', sass.logError))
        .pipe(autoPrefixer({
            browsers: ['last 3 versions'],
            cascade: false
        }))
        .pipe(sourceMaps.write())
        .pipe(gulp.dest(config.css))
        .pipe(liveReload());
});

// jade
gulp.task('markup', function() {
    return gulp.src([['src/**/*.jade', 'src/**/_*.jade']])
        .pipe(jade({
            pretty: true
        }))
        .pipe(gulp.dest(config.markup))
        .pipe(liveReload());
});

// Images
gulp.task('images', function() {
    return gulp.src(['src/images/**/*.*', 'src/images/*.*'])
        .pipe(gulp.dest(config.images));
});

// Watch
gulp.task('watch', function() {
    liveReload.listen();
    gulp.watch(['src/ts/*.ts', 'src/ts/**/*.ts'], ['scripts']);
    gulp.watch(['src/sass/*.scss', 'src/sass/**/*.scss'], ['sass']);
    gulp.watch(['src/*.jade', 'src/**/*.jade'], ['markup']);
});

// Default Task
gulp.task('default', function() {
    gulp.start('sass', 'scripts', 'markup', 'images', 'watch');
});

// Dist Scripts
gulp.task('distScripts', function() {
    return gulp.src(['src/ts/plugins/**/*', 'src/ts/*.js'], { "base" : "./src/ts" })
        .pipe(gulp.dest(config.js));
});

// Dist Styles
gulp.task('distStyles', function() {
    return gulp.src('src/sass/**/*.css', { "base" : "./src/sass" })
        .pipe(autoPrefixer({
            browsers: ['last 3 versions'],
            cascade: false
        }))
        .pipe(gulp.dest(config.css));
});

// Dist Fonts
gulp.task('distFonts', function() {
    return gulp.src('src/fonts/**/*', { "base" : "./src/fonts" })
    .pipe(gulp.dest(config.fonts));
});


// Dist
gulp.task('dist', function() {
    gulp.start('distScripts', 'distStyles', 'images', 'distFonts');
});

这是我在运行“gulp”时收到的消息:

知道为什么吗？似乎在渲染 Jade 时会发生这种情况……当然，所有依赖项都已安装。

Answer 1

似乎您正在使用多维数组[["item1","item2"]]。要使用 gulp.src() 读取文件，您应该使用像 'path/to/*.jade' 这样的字符串或像 ["这样的简单一维数组path/to/first/*.jade", "path/to/second/glob/**/*.jade"].

在您的情况下，JADE-Task 应如下所示:

// jade
gulp.task('markup', function() {
    return gulp.src(['src/**/*.jade', 'src/**/_*.jade'])
        .pipe(jade({
            pretty: true
        }))
        .pipe(gulp.dest(config.markup))
        .pipe(liveReload());
});

关于您的观察任务:

您应该在自己的任务中调用您的 livereload 作为您的监视任务的回调。还建议定义目标文件夹的根路径，作为 liveReload() 对象中的参数选项。

// Watch
gulp.task('livereload', function() {
    return gulp.src('./dist')
       .pipe(
          liveReload({
             start: true,
             basePath: 'path/to/destination'
          })
       );
});
gulp.task('watch', ['livereload'], function() {
    liveReload.listen()
    gulp.watch(['src/ts/*.ts', 'src/ts/**/*.ts'], ['scripts']);
    gulp.watch(['src/sass/*.scss', 'src/sass/**/*.scss'], ['sass']);
    gulp.watch(['src/*.jade', 'src/**/*.jade'], ['markup']);
});

不要忘记在默认任务中启动监视任务

// Dist
gulp.task('dist', ['watch'], function() {
    gulp.start('distScripts', 'distStyles', 'images', 'distFonts');
});
