我最近在 Heroku 上启动了一个应用程序git push heroku master，并遇到了一些错误：
remote: raise ValueError("Missing distribution spec", line)
remote: ValueError: ('Missing distribution spec', '+ Python (2.7)')
然而，我随后得到了
remote: -----> Compressing... done, 36.5MB
remote: -----> Launching... done, v5
表明应用程序已启动成功。
不幸的是，如果我尝试访问托管该应用程序的页面，我会收到一条包含以下消息的页面：
An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
我检查了日志，发现有一个错误，代码为 H14 - 应用程序没有与之关联的测功机。我自然而然地想添加一个测功机，但 Heroku 根本不让我添加。根本没有“编辑”选项。我检查了这个问题发现它与我的情况不太相似，因为据我所知，Heroku 允许我启动该应用程序，因此我认为上述错误并不严重。我错过了什么？
请参阅下文以了解完整git push输出。
