sip 模块实现 API v11.0 到 v11.2 但 PyQt5.QtCore 模块需要 API v11.3

Question

我对这个错误有疑问。作为记录，我使用的是 PyQt4。感谢您的帮助！

Answer 1

我使用 pip 卸载并重新安装 sip 解决了这个问题。

pip uninstall sip
pip install sip

只是进行升级可能也有效，但我在升级过程中遇到错误，因为文件正在使用中。

在 Anaconda 中执行等效操作可能会解决问题。

Answer 2

我在 pycharm 和 pyqt4 上遇到了同样的错误……对我来说，解决方案是：

python版本（在我的例子中是python3.4）和 pyqt4 版本必须匹配 ... 所以我安装了 python-3.4.4.msi 然后安装了 PyQt4-4.11.4-gpl-Py3.4-Qt4.8。 -x32.exe

现在可以了

sip 模块实现 API v11.0 到 v11.2 但 PyQt5.QtCore 模块需要 API v11.3

The sip module implements API v11.0 to v11.2 but the PyQt5.QtCore module requires API v11.3

python
