mac上的PythonpplerQT5安装错误

Question

我正在尝试安装程序包python_poppler-qt5，但出现以下错误：

pip install python-poppler-qt5

因此，这似乎是一个版本冲突。你能帮我找出解决这个问题的办法吗

安装环境

• macOS Catalina v 10.15.4
• PythonV3.7.6
• PyQt5 v 5.15.4

在通过自制取消安装Qt6并安装Qt5后，我出现以下错误：

pip install python-poppler-qt5

Answer 1

第一个错误是由于使用编译PyQt5的不同版本造成的，在本例中使用了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的代码有一个bug，在这种情况下，解决方案是使用项目存储库中的代码并直接编译：

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