python - [31m 文本而不是颜色的输出

Question

我正在尝试使用 colorama 打印彩色文本，但是当我编译一个 exe 并运行以下...

from colorama import Fore, Back, Style
print(Fore.RED + 'text')
print(Back.GREEN + 'and with a green background')
print(Style.DIM + 'and in dim text')
print(Style.RESET_ALL)
print('back to normal now')
I get output of::

输出:

[31mtext
[0m
back to normal now

编译为 pyinstaller exe 时是否可以打印颜色，或者这根本不可能？

在 Windows 上，您必须使用 colorama.init() 初始化 Colorama(见第二行):

from colorama import Fore, Back, Style
colorama.init()
print(Fore.RED + 'text')
print(Back.GREEN + 'and with a green background')
print(Style.DIM + 'and in dim text')
print(Style.RESET_ALL)
print('back to normal now')

我已经在 cmd 和 PowerShell 中测试了这段代码，它产生了预期的彩色输出。

来自 Colorama docs :

On Windows, calling init() will filter ANSI escape sequences out of any text sent to stdout or stderr, and replace them with equivalent Win32 calls.

On other platforms, calling init() has no effect (unless you request other optional functionality; see “Init Keyword Args”, below). By design, this permits applications to call init() unconditionally on all platforms, after which ANSI output should just work.
