当部署到Heroku时，在grunt上找不到模块

Cannot find module on grunt when deploying to Heroku

本文关键字：grunt 找不到 模块 部署 Heroku      更新时间：2023-09-26

这真让我困惑。基本上，我设置了一个Go应用程序，使用Grunt作为web应用程序。

我使用https://github.com/ddollar/heroku-buildpack-multi为我的构建包结合nodejs和去构建包，我不能得到nodejs的构建包工作。

我设法安装grunt，而执行我的grunt任务只是未能获得模块。下面的Heroku输出:

请注意，我故意调用ls ./node_modules/react来查看它是否已安装。但由于某些原因，它无法在我的节点文件中找到它。

我Gruntfile

: 

module.exports = function(grunt) {
  grunt.loadNpmTasks('grunt-react')
  grunt.loadNpmTasks('grunt-browserify')
  // doing this for testing - fails on heroku
  var react= require('React')
  grunt.initConfig({
    browserify: {
      options: {
        transform: [require('grunt-react').browserify]
      },
      app: {
        src: 'src/app.react.js',
        dest: 'public/index.js'
      }
    },
  })
  grunt.registerTask('heroku:deploy', [
    'browserify:app'
  ])
}

和包。json文件:

{
  "name": "blat",
  "version": "0.0.0",
  "description": "",
  "engines": {
    "node": "0.10.x",
    "npm": "1.4.x"
  },
  "dependencies": {
    "director": "^1.2.3",
    "es6-promise": "^1.0.0",
    "grunt": "^0.4.5",
    "grunt-cli": "^0.1.13",
    "grunt-react": "^0.9.0",
    "react": "^0.11.1",
    "react-router": "^0.5.2",
    "superagent": "^0.18.2",
    "superagent-prefix": "0.0.2"
  },
  "devDependencies": {},
  "scripts": {
    "postinstall": "echo postinstall time; ./node_modules/grunt-cli/bin/grunt heroku:deploy"
  }
}

.buildpacks 

https://github.com/heroku/heroku-buildpack-nodejs.git
https://github.com/kr/heroku-buildpack-go.git

Heroku配置:

BUILDPACK_URL = https://github.com/ddollar/heroku-buildpack-multi.git
NODE_ENV = production

有谁知道是什么问题吗?我不能在本地复制它，这太令人沮丧了。我试过https://github.com/mbuchetics/heroku-buildpack-nodejs-grunt buildpack，但它给了我相同的结果。

Ok原来是大小写敏感的问题。显然，我使用HFS+不区分大小写的格式，这解释了为什么我的代码在本地工作。
