如何修复 Windows 中未安装 scons 的问题？

Question

我在c++中使用godot，它原生的c++需要安装scons。我正常安装了scons。但这引起了一个问题：

C:\Users\Admin\AppData\Roaming\Python\Python312\site-packages\setuptools\__init__.py:80: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated.
!!

        ********************************************************************************
        Requirements should be satisfied by a PEP 517 installer.
        If you are using pip, you can try `pip install --use-pep517`.

        ********************************************************************************
        Please avoid running ``setup.py`` directly.
        Instead, use pypa/build, pypa/installer or other
        standards-based tools.

error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: 'C:\\Program Files\\Python312\\Lib\\site-packages\\test-easy-install-1112.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    C:\Program Files\Python312\Lib\site-packages\

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  https://setuptools.pypa.io/en/latest/deprecated/easy_install.html

Please make the appropriate changes for your system and try again.
I think this is error is in the file. So i use pip :"pip install scons". It run normally and i type "scons --version".But it say...
'scons' is not recognized as an internal or external command,
operable program or batch file.
I was search the internet and do like it. But nothing happend.

这是我的 scons 文件：

这就是错误问题：

还有这个：

所以我通过“pip uninstall scons”删除了scons。我再次下载，但没有任何进展。 你能帮我吗？

系列，因为我是堆栈溢出的新手

尝试：

python -nSCons 

安装 SCons（和/或任何 python 包恕我直言）的一个非常好的方法是将它们安装在 virtualenv 中。 您可以在我们的食谱中找到说明：https://scons-cookbook.readthedocs.io/en/latest/#setting-up-a-python-virtualenv-for-scons
