最佳答案
我遇到了与您描述的完全相同的问题。
在此之前，使用PyMuPDF / Fitz，我的Django Heroku应用程序运行正常，没有任何问题。因此，我只能得出这样的结论：构建失败是一个全新的问题，需要进行一些更改。
就我而言，我最近更新了包括PyMuPDF在内的依赖项。
解决我问题的方法是将PyMuPDF锁定在1.16.0版。
pymupdf =“ == 1.16.0”
我认为撰写本文时的最新版本是1.16.1或1.16.2。
我不是100％知道根本原因，但我怀疑是因为最新版本的PyMuPDF可能不允许与较早版本的pip向后兼容。
检查运行在我的实时Heroku dyno上的pip版本后，我得到：
“您正在使用pip版本9.0.2，但是版本20.0.2可用。”
如果您使用默认的Heroku Python环境，则可能同样适用。
让我们知道冻结您的PyMuPDF版本是否也可以解决您的问题！
