Pycharm、PyQt5 和 Python 2.7——没有代码完成

2022-01-12 00:00:00 python pyqt pyqt5 pycharm code-completion

问题描述

我有:

  • Python 2.7 (Anaconda x64)，效果很好
  • PyQt5(使用 pip install python-qt5 安装)
  • PyCharm 4.04 Professional(最近从 3.4.1 升级)
  • 一个小型Qt应用程序
  • Python 2.7 (Anaconda x64), which works great
  • PyQt5 (installed using pip install python-qt5)
  • PyCharm 4.04 Professional (recently upgraded from 3.4.1)
  • A small Qt application

费尽心思(因为 Riverbank 没有为 Python 2.7 提供 PyQt5 二进制文件，仅适用于3.3+) 多亏了 Marcus Otosson 的 预编译的二进制包，我得到了一切工作.

After much hair-pulling (since Riverbank doesn't provide a PyQt5 binary for Python 2.7, only for 3.3+) I got everything working thanks to Marcus Otosson's pre-compiled binary packages.

Qt 现在已安装并且功能齐全.我的 Qt 应用程序运行良好！

Qt is now installed and fully functional. My Qt application runs great!

但应用程序尚未完成，并且 PyCharm 不会为 PyQt 模块完成代码完成.它甚至无法识别任何 PyQt5 子模块(如 Qwidgets)的存在:即使它们工作得很好，我仍然会收到红色波浪形 "Unresolved Reference" 警告.

But the application isn't finished yet, and PyCharm won't do code completion for the PyQt modules. It won't even recognize that any PyQt5 sub-modules (like Qwidgets) exist: even though they work just fine, I still get the red squiggly "Unresolved Reference" warning.

我该如何解决这个问题?我认为这与为二进制 *.pyd 文件生成骨架的固有困难有关.它是如何工作的?我可以手动生成代码骨架，还是从它们正确生成的地方导入它们?

How do I fix this? I assume this has to do with the inherent difficulties in generating skeletons for binary *.pyd files. How does it work exactly? Can I manually generate code skeletons, or import them from somewhere they generated correctly?

卸载并重新安装 PyCharm 没有帮助.重新配置解释器也没有强制骨架生成器再次运行.

Uninstalling and re-installing PyCharm didn't help. Neither did re-configuring the interpreter to force the skeleton generator to run again.

在我秃顶之前请帮忙.

解决方案

在 PyCharm 2017.1.1 中遇到了同样的问题.不要这样做

Had the same problem in PyCharm 2017.1.1. Don't do

import PyQt5.QtWidgets

做

from PyQt5 import QtWidgets
