Python和节点.js关于赫罗库

Question

我已经开始制作一个在Heroku上运行的节点服务器。我试着用非官方的API。我编写了以下Python脚本来连接到API：

import duolingo
import simplejson as json

lingo  = duolingo.Duolingo('harleyrowland')
print json.dumps(lingo.get_user_info())

我的节点服务器使用以下命令：

^{pr2}$

这一切在当地都很好。在

当我把这个推给Heroku时，代码不起作用，我开始在Heroku日志中得到以下错误：

{ [Error: ImportError: No module named duolingo]
     2016-10-06T00:02:32.133315+00:00 app[web.1]:   traceback: 'Traceback (most recent call last):\n  File "duoScript.py", line 1, in <module>\n    import duolingo\nImportError: No module named duolingo\n',
    executable: 'python',
    options: null,
    script: 'duoScript.py',
    args: null,
    exitCode: 1 
}

因此，我继续Heroku API，发现我需要添加一个要求.txt文件。所以我做了：

duolingo-api==0.3
simplejson==3.8.2

但还是没用。然后我找到了this答案并添加了一个.buildpacks文件：

https://github.com/heroku/heroku-buildpack-python.git
https://github.com/heroku/heroku-buildpack-nodejs.git

我还是犯了同样的错误。在

知道是什么导致了这个错误吗？在

更新1

我想我会把我的程序文件也显示出来，以防出现问题：

web: node index.js
pipinstall: pip install -r requirements.txt

更新2

不带git push heroku master的git push heroku master的输出：

Answer 1

尝试删除不推荐使用的heroku-buildpack-multi，并使用Heroku ^{}命令：

$ heroku buildpacks:add  index 1 heroku/nodejs
$ heroku buildpacks:add  index 2 heroku/python
