Question

我向Heroku部署了一个使用gulp的NodeJS应用，但它无法在Heroku上工作。

此处package.json：

{
  "name": "app-name",
  "version": "1.0.0",
  "previewUrl": "http://blahblah.com",
  "publishUrl": "gs://blahblah.com",
  "description": "",
  "repository": {
    "type": "git",
    "url": "git://github.com/github_username/git_repo.git"
  },
  "devDependencies": {
    "browser-sync": "*",
    "browserify": "*",
    "gulp": "*",
    "gulp-autoprefixer": "*",
    "gulp-changed": "*",
    "gulp-filesize": "*",
    "gulp-imagemin": "*",
    "gulp-minify-css": "*",
    "gulp-notify": "*",
    "gulp-rev-all": "*",
    "gulp-sass": "*",
    "gulp-sourcemaps": "*",
    "gulp-uglify": "*",
    "gulp-util": "*",
    "lodash": "*",
    "pretty-hrtime": "*",
    "require-dir": "*",
    "velocity-animate": "^1.2.2",
    "vinyl-source-stream": "*",
    "watchify": "*"
  },
  "dependencies": {
    "underscore": "~1.7.0",
    "jquery": "~2.1.0",
    "keen-js": "~3.2.4",
    "superagent": "~1.2.0"
  }
}

此处gulpfile.js：

var requireDir = require('require-dir');

// Require all tasks in gulp/tasks, including subfolders
requireDir('./gulp/tasks', { recurse: true });

此处Procfile：

`web: gulp`

当我部署到Heroku并转到托管应用程序的网站时，我得到了一个＆＃34;应用程序失败＆＃34;错误。当我检查我的Heroku日志时，这就是我所看到的：

2016-10-27T22:20:10.439111+00:00 heroku[web.1]: Starting process with command `gulp`
2016-10-27T22:20:12.282952+00:00 app[web.1]: bash: gulp: command not found
2016-10-27T22:20:12.376610+00:00 heroku[web.1]: Process exited with status 127

2016-10-27T22:20:14.527034+00:00 heroku[web.1]: Starting process with command `gulp`

为什么应用会这样做？

我可能错了，但我认为这是由于你的Procfile中gulp的路径。

web: gulp意味着您在远程计算机上全局安装了gulp，而实际上每个Heroku构建都以新鲜的dyno开始（即没有对dyno的目的作出假设，因此存在很少，如果有的话，预先安装的模块超出了基础知识）。简而言之，它找不到gulp作为全局安装的模块。

尝试更新Procfile以使用本地安装的gulp模块：web: ./node_modules/gulp/bin/gulp。

如何在Heroku上运行gulp？
