当用PY Launcher调用模块时，为什么我必须用下划线替换所有连字符？

我正在使用 python parinterer Windows简化版本管理并避免修改系统路径。

我已经成功安装了一些软件包：

> py -m pip list
Package            Version
------------------ ---------
Brotli             1.0.9
certifi            2021.10.8
charset-normalizer 2.0.12
gallery-dl         1.21.1
idna               3.3
mutagen            1.45.1
pip                22.0.4
pycryptodomex      3.14.1
requests           2.27.1
setuptools         58.1.0
urllib3            1.26.9
websockets         10.3
yt-dlp             2022.4.8

它们均在Program Files/Python310/Scripts中列出：

但是当我尝试称呼他们时，我会收到以下错误：

> py -m gallery-dl
C:\Program Files\Python310\python.exe: No module named gallery-dl

除非我用下划线替换连字符：

> py -m gallery_dl --help
usage: __main__.py [OPTION]... URL...

General Options:
...

这与我不使用发射器并在路径中使用Python的情况大不相同，并且可以在PowerShell内部拨打Gallery -dl，而无需：

准备py -m - 可以用下划线
替换连字符 - 这不太好，因为它感觉就像我在调用
具有__ main __. py： bit的原始功能 -对了。

这是预期和适当的行为，还是[我在做 /做我做的]错误？

原文

I'm using the Python launcher on Windows to simplify version management and avoid modifying system path.

I've successfully installed a few packages:

> py -m pip list
Package            Version
------------------ ---------
Brotli             1.0.9
certifi            2021.10.8
charset-normalizer 2.0.12
gallery-dl         1.21.1
idna               3.3
mutagen            1.45.1
pip                22.0.4
pycryptodomex      3.14.1
requests           2.27.1
setuptools         58.1.0
urllib3            1.26.9
websockets         10.3
yt-dlp             2022.4.8

They're all listed under Program Files/Python310/Scripts:

but when I try to call them I get the following error:

> py -m gallery-dl
C:\Program Files\Python310\python.exe: No module named gallery-dl

unless I replace hyphens with underscores:

> py -m gallery_dl --help
usage: __main__.py [OPTION]... URL...

General Options:
...

This is quite different from when I wasn't using the launcher and had python in PATH and could just call gallery-dl inside Powershell without:

prepending py -m - which is fine
replacing hyphens with underscores - which is less fine because it sort of feels like I'm calling a raw function
having the __main__.py: bit - which doesn't feel right either.

Is this the expected and proper behavior, or [am I doing / did I do] something wrong?
