Heroku 的 Django 项目无法使用 pip 安装依赖项

Question

我正在尝试在 Heroku 上部署一个 django 项目。我使用 virtualenv 和 pip 来管理依赖项。 virtualenv 版本是 1.7.1，它附带的 pip 是 1.1。我试图强制 --no-site-packages 但它提示它现在是默认行为。另外我确定我在虚拟环境中安装了所有东西。 django 项目是空的。我遵循了here 的说明。也许问题在于他们的 pip 和 virtualenv 版本较旧？有没有人遇到过这个问题？提前谢谢你。

ψ pip.exe freeze
Django==1.3.1
distribute==0.6.24
versiontools==1.8.3
(venv)

ψ more .\requirements.txt
Django==1.3.1
distribute==0.6.24
versiontools==1.8.3

(venv)

ψ git push heroku master

似乎问题出在 requirements.txt 中，我使用 powershell 和“pip.exe freeze > requirements.txt”命令创建了它， 它会创建一个名称中包含空字节的文件。 我可以通过从 github 上的示例项目下载 requirements.txt 并对其进行修改来解决这个问题。 完成了这项工作，一切都很好。
