【问题描述】：
我正在尝试将一个应用程序部署到 heroku，它是一个非常简单的应用程序，但是当我尝试使用 push heroku master 进行部署时，我收到以下错误
(env) PS C:\Users\xblade\Desktop\F1> git push heroku master

这似乎与requirements.txt 有关。
它试图安装一些pip 要求但它失败了。
我认为这与distutils 有关。我尝试上传，除了 1 之外没有任何要求，它工作正常（但应用程序不起作用）。
问题似乎在于烧瓶包及其附加包，例如itsdangerous。
这是 requirements.txt 中的包列表
click==6.7
Flask==0.12.2
Flask-SQLAlchemy==2.3.2
Flask-WTF==0.14.2
gunicorn==19.7.1
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
psycopg2==2.7.4
SQLAlchemy==1.2.5
Werkzeug==0.14.1
WTForms==2.1
有谁知道为什么这个部署会失败，我可以做些什么来解决它？
谢谢

我最终获取了项目的所有文件并重新制作了一个新的 git 存储库和一个新的 heroku 应用程序，它现在工作正常，但原来的仍然无法工作，我不知道为什么。另一个项目和应用程序中的相同文件可以完美运行。
