我正在尝试在Heroku上部署django项目。我使用virtualenv和pip来管理依赖项。 virtualenv版本是1.7.1,pip随附它是1.1。我试图强制使用--no-site-packages,但它提示它现在是默认行为。此外,我确信我在虚拟环境中安装了所有内容。 django项目是空的。我按照here的说明进行操作。也许问题是他们的pip和virtualenv版本更老?有谁遇到过这个问题?提前谢谢。

似乎问题出现在requirements.txt中,我是使用powershell和“pip.exe freeze> requirements.txt”命令创建的, 它创建一个名称中包含nullbytes的文件。 我能够通过从github上的示例项目下载requirements.txt并修改它来解决这个问题。 这完成了工作,一切都很好。
