Javascript grunt sftp部署authKey ftppass

我通过grunt sftp部署（verbose）接收到这个错误

我刚开始使用grunt，只需要将通过sass生成的watch css上传到服务器上的某个点

    Registering "grunt-sftp-deploy" local Npm module tasks.

那么gruntfile.js就是这样的

module.exports = function (grunt) {

  // load all grunt tasks
  require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    'sftp-deploy': {
      build: {
        auth: {
          host: 'XXX.XXX.XXX.XXX',
          port: 22,
          authKey: 'key1'
        },
        cache: 'sftpCache.json',
        src: '../css',
        dest: '/server/path',
        exclusions: [
        ],
        serverSep: '/',
        concurrency: 4,
        progress: true
      }
    },

    sass: {
      dist: {
        options: {
          style: 'expanded',
          noCache: true
        },
        files: [{
          expand: true,
          cwd: '../sass/pages', 
          src: ["**/*.scss"], 
          dest: '../css', 
          ext: ".css"
          }]
      }
    },

    watch: {
      options: {
        nospawn: true,
        nocache: true,
        livereload: true
      },
      sass: {
        files: ['../sass/**/*.scss'],
        tasks: ['sass']
      },
      sftp: {
        files: ['../css/**/*.css'],
        tasks: ['sftp-deploy']
      }
    }

  });

  grunt.loadNpmTasks('grunt-sftp-deploy');
  grunt.registerTask('default', ['watch']);
};

Sass是对的，但我找不到为什么不将文件上传到服务器

那么我的问题是:

我错过了什么？ 哪个路径应该是.ftppass.json？ 现在和gruntfile.js是同一个地方，但我也有问题，我怀疑这是不对的。但是在sftp deploy gruntile.js设置中没有空间设置.ftppass.json。 如何正确设置路径

.ftppass.json

{
  "key1": {
    "username": "username",
    "password": "pass"
  }
}

---

它只是

.ftppass

，最后没有.json。将它放在与Grunfile.js相同的目录中即可

您是否找到了解决方案？我也有同样的问题
