python-ppler-qt5在mac上安装错误

Question

我正在尝试安装python_poppler-qt5包，但我遇到了以下错误：

pip install python-poppler-qt5

所以这似乎是一个版本冲突。你能帮我想办法解决这个问题吗？

安装环境

• macOS Catalina v 10.15.4
• python v3.7.6
• PyQt5 v 5.15.4

在通过自制软件卸载Qt6并安装Qt5后，我得到了以下错误：

pip install python-poppler-qt5

Answer 1

第一个错误是由于使用了编译PyQt5的不同版本引起的，在本例中，使用了Qt6，但编译PyQt5时使用了Qt 5.15.4。

第二个错误是因为上传到pypi的代码有一个错误，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
