mac上的python-poppler-qt5安装错误

问题描述

我正在尝试安装软件包 python_poppler-qt5，但出现以下错误：

pip install python-poppler-qt5

所以好像是版本冲突。你能帮我弄清楚如何解决这个问题吗？

安装环境

• macOS Catalina v 10.15.4
• python v 3.7.6
• PyQt5 v 5.15.4

在卸载 Qt6 并通过自制软件安装 Qt5 后，我收到以下错误：

pip install python-poppler-qt5

解决方法

第一个错误是由于使用了不同的 PyQt5 编译版本引起的，在这种情况下使用的是 Qt6，但 PyQt5 是使用 Qt 5.15.4 编译的。

第二个错误是因为上传到pypi的代码有bug，这种情况的解决办法是使用项目仓库中的代码，直接编译：

pip install PyQt-builder sip
git clone https://github.com/frescobaldi/python-poppler-qt5
cd python-poppler-qt5
sip-build
sip-install
