向 Windows 添加“DEBUG=1"命令?

2022-01-15 00:00:00 python kivy windows powershell

问题描述

我正在尝试使用 kaki带有 kivy 和 python 的库，但要使用它，您需要运行

I'm trying to use kaki library with kivy and python but to use it you need to run

DEBUG=1 python main.py

但我遇到了这个错误

DEBUG=1 : The term 'DEBUG=1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that 
the path is correct and try again.
At line:1 char:1
+ DEBUG=1 python main.py
+ ~~~~~~~
    + CategoryInfo          : ObjectNotFound: (DEBUG=1:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

但我可以找到有关如何将此命令添加到我的路径的任何来源

but I can find any source about how to add this command to my path

我正在使用

python:3.7
窗户 10

python:3.7
windows 10

如果需要，我会添加任何信息

I will add any information if need it

解决方案

在 PowerShell 中，您可以写入将由子进程继承的环境变量，如下所示:

In PowerShell, you can write to an environment variable which will be inherited by child processes, like this:

PS ~> $env:DEBUG = 1
PS ~> python main.py

或者作为一行中的两个语句:

Or as two statements on a single line:

$env:DEBUG = 1; python main.py

Python 现在在解析 DEBUG 环境变量时将获得值 1

Python will now get the value 1 when resolving the DEBUG environment variable

在cmd.exe中可以使用set关键字:

C:> set "DEBUG=1" && python main.py
