如何在 Heroku Django 上安装 PyMuPDF
How to Install PyMuPDF on Heroku Django
我正在尝试制作一个从 PDF 中提取图像的脚本，我在 Django 项目中制作了一个脚本并将 pymupdf 添加到 requirements.txt.I 有一个带有 Mupdf 的 Aptfile 和 https://github.com/heroku/heroku-buildpack-apt作为 buildpack 和 heroku/python。在尝试将 master 推送到 Heroku 时，推送失败，这是错误。

我遇到了与您描述的完全相同的问题。
在此之前，我的 Django Heroku 应用程序使用 PyMuPDF / Fitz 时工作正常，没有任何问题。所以我得出结论，这个构建失败是一个全新的问题，导致了一些变化。
就我而言，我最近刚刚更新了我的依赖项，其中包括 PyMuPDF。
解决我问题的方法是将 PyMuPDF 锁定在 1.16.0 版本。
pymupdf = "==1.16.0"
我认为截至撰写本文时的最新版本是 1.16.1 或 1.16.2。
我不是 100% 确定根本原因，但我怀疑这是因为最新版本的 PyMuPDF 可能不允许向后兼容旧版本的 pip。
在我的 live Heroku dyno 上检查 pip 版本 运行 后，我得到：
"You are using pip version 9.0.2, however version 20.0.2 is available."
如果您使用默认的 Heroku Python 环境，同样适用于您。
如果冻结您的 PyMuPDF 版本也能为您解决问题，请告诉我们！
经过一些调试，我已经解决了这个问题。
问题出在新版本的 PyMuPDF 上，因此，我没有使用最新版本的 PyMuPdf，而是使用了旧版本。
在 Aptfile 中，不添加 Mupdf-tools，而是添加
http://ftp.br.debian.org/debian/pool/main/m/mupdf/mupdf_1.14.0+ds1-4_amd64.deb
在 requirements.txt 中，不添加 PyMuPDF，而是添加
PyMuPDF==1.14.20
这应该可以解决。
我正在尝试制作一个从 PDF 中提取图像的脚本，我在 Django 项目中制作了一个脚本并将 pymupdf 添加到 requirements.txt.I 有一个带有 Mupdf 的 Aptfile 和 https://github.com/heroku/heroku-buildpack-apt作为 buildpack 和 heroku/python。在尝试将 master 推送到 Heroku 时，推送失败，这是错误。

我遇到了与您描述的完全相同的问题。
在此之前，我的 Django Heroku 应用程序使用 PyMuPDF / Fitz 时工作正常，没有任何问题。所以我得出结论，这个构建失败是一个全新的问题，导致了一些变化。
就我而言，我最近刚刚更新了我的依赖项，其中包括 PyMuPDF。
解决我问题的方法是将 PyMuPDF 锁定在 1.16.0 版本。
pymupdf = "==1.16.0"
我认为截至撰写本文时的最新版本是 1.16.1 或 1.16.2。
我不是 100% 确定根本原因，但我怀疑这是因为最新版本的 PyMuPDF 可能不允许向后兼容旧版本的 pip。
在我的 live Heroku dyno 上检查 pip 版本 运行 后，我得到：
"You are using pip version 9.0.2, however version 20.0.2 is available."
如果您使用默认的 Heroku Python 环境，同样适用于您。
如果冻结您的 PyMuPDF 版本也能为您解决问题，请告诉我们！
经过一些调试，我已经解决了这个问题。
问题出在新版本的 PyMuPDF 上，因此，我没有使用最新版本的 PyMuPdf，而是使用了旧版本。
在 Aptfile 中，不添加 Mupdf-tools，而是添加
http://ftp.br.debian.org/debian/pool/main/m/mupdf/mupdf_1.14.0+ds1-4_amd64.deb
在 requirements.txt 中，不添加 PyMuPDF，而是添加
PyMuPDF==1.14.20
这应该可以解决。
