如何致电QT_SCALE_FACTOR?

问题描述

我的计算机上安装了Anaconda.但是，当我打开Spyder时，它看起来很糟糕，因为DPI很高.我被告知运行QT_SCALE_FACTOR=2.5 spyder来解决问题.但是，我回来了'QT_SCALE_FACTOR' is not recognized as an internal or external command, operable program or batch file.，这令人沮丧，因为我通过Anaconda安装了pyqt.这也是我的路径C:\...\Anaconda3\Lib\site-packages\PyQt5的一部分如果我呼叫qmake -query，我会得到:

I have Anaconda installed on my computer. When I open Spyder though, it looks terrible because the DPI is high. I've been told to run QT_SCALE_FACTOR=2.5 spyder to solve the problem. However, I get back 'QT_SCALE_FACTOR' is not recognized as an internal or external command, operable program or batch file. This is frustrating because I have pyqt installed through Anaconda. It's also part of my path C:\...\Anaconda3\Lib\site-packages\PyQt5 If I call qmake -query, I get:

如您所见，看来我已经安装好了.我怎么不能打电话给QT_SCALE_FACTOR?我怎样才能正确地做到这一点?谢谢！ (顺便说一句，如果有帮助，我正在运行Windows 10.)

So as you can see, it appears I have it installed just fine. How come I can't call QT_SCALE_FACTOR? How can I do that correctly? Thanks! (Incidentally, I'm running Windows 10 if that helps.)

推荐答案

在Windows控制台(cmd.exe)中运行下一个命令:

Run next commands in windows console (cmd.exe):

set QT_SCALE_FACTOR=2.5
spyder
