Python Bluemix flask应用程序不再构建

我在bluemix上有一个烧瓶应用程序。它工作得很好。我在一个htmls中更改了一些文本（不应该与之有任何关系）

有一段时间没有检查它，但似乎它突然无法构建（重新启动后停止）

（从这里它们是红色的）

看来问题是

pandas-highcharts==0.5.2

在需求文件中

它似乎与安装setuptools-21.0.0依赖项有关。因此，setuptools-18.3.2被卸载并删除，如日志中所示：

2016-05-09T12:47:10.424+0200[STG/0]输出

采集设置工具>=18.5（来自ipython->pandas highcharts==0.5.2->-r requirements.txt（第5行））

2016-05-09T12:47:11.162+0200[STG/0]OUT

卸载setuptools-18.3.2:

2016-05-09T12:47:11.181+0200[STG/0]OUT

已成功卸载setuptools-18.3.2

稍后，由于找不到setuptools-18.3.2，生成操作失败

在查看了Github上的相关源代码后，我不知道具体是哪里导致了问题

我采用的解决方案是将其移除。取而代之的是，我在情节上使用了其他东西

（如果有人知道原因，我们可以对其进行编辑以包括原因。了解原因可能有助于将来的使用）。

是否可以尝试使用

-b部署应用程序https://github.com/cloudfoundry/python-buildpack.git#v1.5.1

我也犯了同样的错误。我做的唯一一件事就是添加需求。在问题@jgawor中添加了这一点

pandas-highcharts==0.5.2
