Question

似乎监视任务在browserSync.init处停止。我可以通过gulp cssInkject调用它们单独运行所有任务，但是他们赢了t run when gulp watch is run. Browsersync will give "File event [change] : resources/assets/styles/modules/_breadcrumbs.css" notification but won运行任务捆绑css并且不会注入CSS（流）。

以下是代码：

var gulp = require('gulp'),
watch = require('gulp-watch'),
browserSync = require('browser-sync').create();

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

    browserSync.init(null, {
        notify: false,
        browser: "chrome",
        server: {baseDir: "app"},
        port: 8000
    });

    watch('./app/*.html', function() {
        browserSync.reload();
    });

    watch('./app/assets/styles/**/*.css', function() {
        gulp.start('cssInject');
    });

    watch('./app/assets/scripts/**/*.js', function() {
        gulp.start('scriptsRefresh');

    });

});

gulp.task('cssInject', ['styles'], function() {
    return gulp.src('./app/temp/styles/styles.css')
    .pipe(browserSync.stream());
});

gulp.task('scriptsRefresh', ['scriptsBundle'], function() {
        browserSync.reload();

    });

gulp.task('styles', function() {
  return gulp.src('./app/assets/styles/styles.css')
    .pipe(postcss([cssImport, mixins, cssvars, nested, hexrgba, autoprefixer]))
    .on('error', function(errorInfo) {
      console.log(errorInfo.toString());
      this.emit('end');
    })
    .pipe(gulp.dest('./app/temp/styles'));
});

我在Ubuntu VM（宅基/ laravel）中运行它，如果它有任何区别。

Answer 1

我不知道它为什么会起作用，但它有效：

gulp.watch('./app/*.html', function() {
    browserSync.reload();
});

gulp.watch('./app/assets/styles/**/*.css', function() {
    gulp.start('cssInject');
});

gulp.watch('./app/assets/scripts/**/*.js', function() {
    gulp.start('scriptsRefresh');

});

基本上添加＆＃39; gulp＆＃39;观看＆＃39;解决了这个问题，因为它与“手表”一起工作更加怪异。只在当地的窗户环境中，而不是在宅基地上。

试试这个

public class DatabaseHandler extends SQLiteOpenHelper {

// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;

// Database Name
public static final String DATABASE_NAME = "OffLineMessagesClient";

// Contacts table name
public static final String TABLE_NAME = "messages_client";

// Contacts Table Columns names
private static final String KEY_ENTITY_ID = "entity_id";
private static final String KEY_MESSAGE = "message";

public DatabaseHandler(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

// Creating Tables
@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_NAME + "("
            + KEY_ENTITY_ID + " INTEGER,"
            + KEY_MESSAGE + " TEXT"
            +  ")";

    db.execSQL(CREATE_CONTACTS_TABLE);
}

// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion,
                      int newVersion) {
    // Drop older table if existed
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);

    // Create tables again
    onCreate(db);
}

public void deleteAll()
{
    SQLiteDatabase db = this.getWritableDatabase();
    db.execSQL("delete from "+ TABLE_NAME);
    db.close();
}
}

Browsersync gulp任务不会注入CSS（或gulp不会在后台运行另一个监视任务）
