pip install在固定到特定版本(django-reversetag)时失败

Question

我的req.txt中有一堆软件包，我通常只需使用以下命令即可将其安装在所有环境中：

pip install -r req.txt

现在，此req文件的一行具有：

django-reversetag==0.3.2

今天，当我进行常规安装时，我出人意料地收到了以下消息：

Exception:

但是，当我简单地更改时：

django-reversetag==0.3.2

自

django-reversetag

..一切似乎都很好...我觉得这很奇怪。我总是被告知将包固定到特定版本。

我不知道为什么这会失败......我有大约 15 个项目使用相同的 req 文件。

任何想法为什么会发生这种情况。

提前谢谢。
