如何在MacOS上安装PyQt5

Question

我试图通过pip或brew在Mac中安装PyQt，但都失败了，出现了sipbuild.pyproject.PyProjectOptionException错误。需要帮助有人能解决这个问题吗？

Answer 1

您使用的是M1 Mac吗？如果是这样的话，这对我来说很有效：我如何用M1芯片在mac上运行pyqt5

如果该页面被删除，有人需要这个：

1. 右键单击Finder中的终端应用程序，然后单击复制
2. 重命名其中一个，以便您知道哪个是哪个
3. 右键单击重命名的，然后单击"；获取信息"；。选中选项"；使用罗塞塔打开">
4. 打开Rosetta版本，创建一个虚拟Python环境。/usr/bin/python3 -m venv env
5. 激活环境。source env/bin/activate
6. 升级pippip install --upgrade pip
7. 安装PyQt5pip install PyQt5

这在运行Big Sur的M1 Air上对我有效，我不能说它在英特尔Mac上是否有帮助。

Answer 2

回答对我有效，但第7步除外，该步骤使用pyqt5失败，但使用pyqt6成功。

pyqt6是为ARM安装的，如下面的输出所示。

在代码中，只需将导入更改为PyQt6即可。存在一些细微的代码差异。

Answer 3

选择的答案几乎说明了一切，它也解决了我的问题。顺便说一句，虚拟环境必须从位于/usr/bin/python3的系统python创建，其他python无法工作。
