python - Heroku 推送被拒绝，无法编译 Python/django 应用程序 (Python 2.7)

Question

我正在做 Heroku 演练:https://devcenter.heroku.com/articles/django#prerequisites对于 python 开发人员，我在尝试运行“git push heroku master”时遇到错误，可以在页面下方大约 1/3 的“部署到 Heroku”部分下找到它。我得到以下回溯:

到目前为止，其他一切都已成功运行。有什么见解吗？我对此完全陌生。提前感谢您的帮助。

这是 requirements.txt 的样子:

Django==1.4.3
distribute==0.6.31
dj-database-url==0.2.1
psycopg2==2.4.5

我认为问题出在您的 requirements.txt 文件的编码中。可能您在不知不觉中将其保存为 Unicode 格式。您应该将其保存为 ANSI 格式。有关详细信息，请参阅此链接:http://georgik.sinusgear.com/2012/08/20/problems-with-deploying-heroku-django-app-from-windows/
