如何在Windows中使用Shebang进行Python？
代码
#! C:\Python310\python.exe
import os
import sys
print(f"PY_PYTHON={os.getenv('PY_PYTHON')}")
print(f"{sys.version=}")
print(f"Shebang : '{open(__file__).read().splitlines()[0]}'")
cmd = 'py -0p'
print(cmd)
os.system(cmd)
cmd = f'file {__file__}'
print(cmd)
os.system(cmd)
输出：
λ py t9.py
PY_PYTHON=None
sys.version='3.11.0a7 (main, Apr 5 2022, 21:27:39) [MSC v.1929 64 bit (AMD64)]'
Shebang : '#! C:\Python310\python.exe'
py -0p
-V:3.11 * C:\Python311\python.exe
-V:3.10 C:\Python310\python.exe
-V:3.9 C:\Users\smart\AppData\Local\Programs\Python\Python39\python.exe
file C:\Users\smart\Desktop\budhubot\budhubot\t9.py
C:\Users\smart\Desktop\budhubot\budhubot\t9.py: a C:\Python310\python.exe script, ASCII text executable, with CRLF line terminator
也尝试过前斜线。
编辑： 没有空间

Tried forward slash too.

Without space

Shebangs不是Windows的东西。
在Windows上，它必须依靠第三方软件：Bash，Cygwin，Python Launcher等。因此，您将在这些第三方软件文档中找到有关其支持的大多数信息。
但是第一件事，我将尝试删除
＃！和解释器的完整路径之间的空间。 Shebang和口译员通常不会被空间隔开。Shebangs aren't a Windows thing.
On Windows, it must rely on a third-party software: bash, cygwin, python launcher, etc. So you'll find most information about its support in these third-party softwares' documentation.
But first thing, I would try to remove the space between
#!and the interpreter's full path. Shebang and interpreter aren't separated by a space usually.在
py.exe位置中添加py.ini文件。注意最后一个字符（使用任何）；没有此，Pylauncher无法正常工作。 （第二支球）。可能是一个错误。 ”

py -u
Add py.ini file in the
py.exelocation.Note the last char (use any); Without this, pylauncher not works. (2nd outptut). Probably a bug. Repo
Edit:
Shebangs are not working with
py -u
