gulp＆＃34;没有这样的文件或目录＆＃34;或＆＃34;文件已存在＆＃34;何时不单独运行任务

时间：2016-10-26 14:45:59

标签： node.js npm gulp

我的Gulp-Tasks导致问题但仅限于我不单独运行。如果我只是运行＆＃34; gulp js＆＃34; everthing工作正常，如果我运行＆＃34; gulp css＆＃34; 或＆＃ 34; gulp clean＆＃34; 。

但如果我运行＆＃34; npm start＆＃34; 

"start": "gulp npm-start && tsc && lite-server && concurrently \"tsc -w\""

任务：npm-start 

gulp.task('npm-start', ['clean-dist', 'build-dev', 'watch']);

结果

  

events.js：141         扔掉//未处理的错误＆＃39;事件         ^

     

错误：EEXIST：文件已经存在，mkdir   ＆＃39; C：\开发\ MyProject的\研发\ myproject的应用程序的UI \程序\ SRC \ CSS＆＃39;       在错误（本机）

OR

  

错误：EEXIST：文件已经存在，mkdir   ＆＃39; C：\开发\ MyProject的\研发\ myproject的应用程序的UI \程序\ SRC \ CSS \ main.css的＆＃39;       在错误（本机）

同时： 如果一切都能正常工作，我会为我创建以下三个目录：

  • 的src / HTML
  • 的src / CSS
  • SRC / JS

我经常遇到并非所有任务都被执行（但终端中没有错误信息）。例如，只有src / html /和src / css /，但不是src / js /。有时src / js和src / css在那里，但缺少src / html。它根本无法正常工作..

我的gulpfile.js 

var gulp = require('gulp'),
    sass = require('gulp-sass'),
    minifyCss = require('gulp-clean-css'),
    minifyJs = require('gulp-minify'),
    minifyHtml = require('gulp-minify-html'),
    clean = require('gulp-clean'),
    watch = require('gulp-watch'),
    gnf = require('gulp-npm-files');

gulp.task('build-dev', [

]);

gulp.task('npm-start', ['clean-dist', 'build-dev']);

    gulp.src('index.html').pipe(gulp.dest('dist'));;

    // Copy (non-dev)dependencies to dist/node_modules/
    gulp.src(gnf(), {base:'./'}).pipe(gulp.dest('dist/node_modules/'));

    // copy compiled typescript files
    gulp.src('./app/**/*.js').pipe(gulp.dest('dist/app'));
    gulp.src('./app/**/*.js.map').pipe(gulp.dest('dist/app'));

    // copy css, html and js
    gulp.src('./app/src/**').pipe(gulp.dest('dist/app/'));
});



/* compiles SCSS to CSS, minifies it and puts it into the right directory */

        .pipe(sass().on('error', sass.logError))
        .pipe(minifyCss())
        .pipe(gulp.dest('app/src/css'));
});



/* minifies JS and puts it into the right directory */

            ext:{
                /*src:'-debug.js', not necessary cause noSource is set to true*/
                min:'.min.js'
            }
        }))
        .pipe(gulp.dest('app/src/js'));
});



/* compiles HTML puts it into the right directory */
// from:  uncompiled-src/html/**.html
// to:    app/src/html/**.html
gulp.task('html', function() {
    gulp.src('uncompiled-src/html/**.html')
        .pipe(minifyHtml())
        .pipe(gulp.dest('app/src/html'));
});



/* removes compiled sources and compiled typescript files */
// from:  app/**
gulp.task('clean', function() {
    gulp.src('app/**/*.js')
        .pipe(clean());
    gulp.src('app/**/*.js.map')
        .pipe(clean());
    gulp.src('app/src/*')
        .pipe(clean());
});



/* removes compiled previously dist directory */
// must be called beforce "tsc" (@see npm script "start")
// because otherwise tsc tries to compile ts-files in dist/node_modules/
gulp.task('clean-dist', function() {
    gulp.src('dist/')
        .pipe(clean());
});



// Rerun the task when a file changes
gulp.task('watch', function() {
    gulp.watch('uncompiled-src/html/*.html', ['html']);
    gulp.watch('uncompiled-src/js/*.js', ['js']);
    gulp.watch('uncompiled-src/scss/*.scss', ['css']);
});

我更新了gulpfile，我添加了return语句。但我仍然遇到了我的＆＃34; js＆＃34;任务。如果我擦除src /文件夹并启动应用程序一切正常，所有任务都会正确执行。如果我重新运行应用程序，我的clean-tasks将被执行，之后会有目录src / html和src / css，但src / js为空。但为什么呢？

    sass = require('gulp-sass'),

// can't run watch-tasks here because it would block the terminal

gulp.task('npm-start', ['clean-dist', 'build-dev']);
