Heroku上的Django項目無法使用pip安裝依賴項

Question

我正在嘗試在Heroku上部署django項目。 我使用virtualenv和pip管理依賴項。 virtualenv版本是1.7.1，其隨附的pip是1.1。 我嘗試強制使用--no-site-packages，但它提示它現在是默認行為。 另外，我確定我會在虛擬環境中安裝所有內容。 django項目是空的。 我按照這里的說明操作。 也許問題在於它們的pip和virtualenv版本較舊？ 有誰遇到過這個問題？ 先感謝您。

ψ pip.exe freeze

ψ more .\requirements.txt

看來問題出在Requirements.txt中，我使用powershell和“ pip.exe Frozen> requirements.txt”命令創建了該文件，該命令創建了一個名稱為nullbytes的文件。 我可以通過從github上的示例項目中下載requirements.txt並進行修改來解決此問題。 做到了這一點，一切都很好。
