此错误与 Dell Boomi 有关，但我认为根本原因更普遍，这就是我决定将其发布在这里的原因
我正在探索程序命令形状以了解它的工作原理和限制。到目前为止，我成功执行了 bat、vbs 和 jar 文件（尽管最后两个仅在实际路径\命令之前执行“cmd /c”之后，即“cmd /c C:\Users\UserX\Desktop\Boomi\hi.罐”）
我想接下来执行 python，但我遇到了“找不到默认 Python”的问题。现在，在您回答“设置环境变量”之前，我已经完成了用户变量和系统变量都具有 python.exe 的路径。当我打开命令提示符时，我可以从任何地方执行脚本 (hi.py)，包括安装 atom 的文件夹，即 atom 的上下文。
当我将 python 启动器设置为调试模式（PYLAUNCHER_DEBUG=1）时，我在命令提示符下运行时得到以下转储：

如您所见，执行成功，但是在 boomi 上运行相同的命令（ cmd /c set PYLAUNCH_DEBUG=1 & C:\Users\UserX\Desktop\Boomi\hi.py）时，这是转储：

通过比较日志，我的猜测是 boomi 无法在 HKCU 中打开密钥？
我进入regedit查看python文件夹的权限并且所有帐户至少具有读取权限，所以除非Boomi使用某种隐藏帐户或临时帐户（我相信它会使用我的帐户，因为atom.exe正在运行它），我不知道为什么它无法读取密钥。
让我来到这里的一般问题是：是否可以拒绝应用程序对 HKCU 的读取访问权限，如果是，我如何将其授予特定应用程序？
