`/ usr / bin / env：节点：heroku上没有这样的文件或目录运行节点

Question

的package.json：

{
  "name": "Promptly-crm",
  "version": "0.0.1",
  "engines": {
    "node": "0.10.x"
  },
  "dependencies": {
    "coffee-script": "^1.7.1",
    "mongodb": "*",
    "body-parser": "*"
  }
}

Procfile：

web: ./node_modules/coffee-script/bin/coffee 1.scrape_in.coffee

错误是：

2014-07-24T01:03:34.341200+00:00 heroku[web.1]: State changed from crashed to starting
2014-07-24T01:03:38.334452+00:00 app[web.1]: /usr/bin/env: node: No such file or directory

2014-07-24T01:03:39.375817+00:00 heroku[web.1]: Process exited with status 127

尝试编译我的咖啡并直接运行。 同样的错误。

我在同一应用程序中有一堆python。 我不能同时使用两种语言吗？

更新

我显然正在使用自定义git buildpack，但不知道哪个：
