是否可以从 setuptools setup.py 中要求 PyQt?-Python问题

Is it possible to require PyQt from setuptools setup.py?(是否可以从 setuptools setup.py 中要求 PyQt?)

本文介绍了是否可以从 setuptools setup.py 中要求 PyQt?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在构建一个使用 PyQt 的小应用程序，并且认为在 setup.py 中声明该依赖项会很好.

I'm building a small app that uses PyQt and tought it'd be nice to declare that dependency in setup.py.

然而，根据这个博客(第一次在谷歌上搜索pyqt setuptools)说无法完成，最后一段这里也不会尝试这样做.

However, according to this blog (first hit on google for pyqt setuptools) says it can't be done, and the last paragraph here doens't try to do it either.

想法?也许我应该切换到 PySide/" rel="noreferrer">PyPi?

Ideas? Perhaps I should switch to PySide which is on PyPi?

更新:

setup.py 中明显的 install_requires = [ 'pyqt >= 0.7' ] 给了我:

The obvious install_requires = [ 'pyqt >= 0.7' ] in setup.py gives me:

推荐答案

虽然接受的答案原本是正确的 Python Wheels现在提供一种无需从源代码编译即可安装 PyQt5 等 C 扩展包的方法.

While the accepted answer was originally correct Python Wheels now provide a means to install C extension packages such as PyQt5 without the need for compilation from source.

PyPi 目前在 Python3 上有多个平台的 PyQt5 的 .whl 文件，包括 MacOS X、Linux(任何)、Win32 和 Win64.例如，这是在 Mac 上的 Python3 上 pip 安装 PyQt5 时的输出:

PyPi currently has .whl files for PyQt5 on Python3 for multiple platforms, including MacOS X, Linux (any), Win32 and Win64. For example, this is the output when pip-installing PyQt5 on Python3 on a Mac:

mfitzp@MacBook-Air ~ $ pip3 install pyqt5

如果您的目标是 Python3+PyQt5，那么在 setup.py 中将 PyQt5 指定为普通依赖项应该没有问题.

If you are targeting Python3+PyQt5 then you should have no problem specifying PyQt5 as a normal dependency in setup.py.
