无法将node.js应用程序部署到heroku

Question

我正在尝试将一个简单的node.js基于表达的应用程序部署到heroku,这显然是非常基本的:https://devcenter.heroku.com/articles/nodejs

这是我的package.json:

{
  "name": "cours-lic3-blois",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app"
  },
  "dependencies": {
    "express": "*",
    "ejs": "*",
    "github-flavored-markdown": "*",
    "less-middleware": "*"
  },
  "engines": {
    "node": "0.8.8",
    "npm": "1.1.65"
  }
}

当我git push heroku master得到以下痕迹时:

 -----> Heroku receiving push
 -----> Node.js app detected
 -----> Resolving engine versions
        Using Node.js version: 0.8.8
        Using npm version: 1.1.65
 -----> Fetching Node.js binaries
 -----> Vendoring node into slug
 -----> Installing dependencies with npm

  ! [remote rejected] master -> master (pre-receive hook declined)

我尝试在我的package.json中调整各种版本,但无济于事.我正在开发Windows,这可能是因为某些文件模式问题导致ENOENT问题.

Answer 1

我得到了这个修复:

• 确保Procfile被提交到git中

• 删除node_modules /文件夹并将其提交到git(git rm -r node_modules /)

之后,我做了git push heroku master然后错误就消失了.

Answer 2

我遇到了这个问题,原因是:

1. 我保持node_modules版本控制
2. 我有bin我的.gitignore文件

npm试图chmod express/bin/express,但由于我的.gitignore这个文件不是在git中,因此在部署期间没有被克隆,所以它失败了.我没注意到它,因为本地npm安装会bin/express像往常一样创建文件.

删除bin从.gitignore和提交丢失的文件解决了这个问题对我来说.
