在我安装了 NI-VISA 的开发 PC 上，一切正常。现在，我尝试通过 cx_Freeze 为其他 PC 制作“一体式”可执行文件。我在 setup.py 中找到了以下 DLL（与我使用 GTK+3 成功完成的方式相同）。

###################

## path to Windows libraries
visa_windows_dir = os.path.join("C:\\", "Windows", "SysWOW64")

## list of missing dlls from Windows directory
missing_visa_windows = [# Listdll.exe(with PyVISA) minus Listdll.exe(without PyVISA)
                    'msvcr71.dll',
                    'nipal32.dll',
                    'nipalu.dll',
                    'NiViSv32.dll',
                    'nipalut.dll',
                    'nirpc.dll',
                    'visa32.dll'
                    #'crypt32.dll',
                    #'msasn1.dll',
                    #'wintrust.dll',
                    #'winusb.dll',
                    #'wsock32.dll'
                ]


## path to visa libraries
visa_program_dir = os.path.join("C:\\", "Program Files (x86)",
                                "IVI Foundation", "VISA", "WinNT")

## list of missing dlls from program directory
missing_visa_program = [# from Listdlls.exe
                        os.path.join("Bin", "NiVi488.dll"),
                        os.path.join("Bin", "NiViAsrl.dll"),
                        os.path.join("Bin", "NiViEnet.dll"),
                        os.path.join("Bin", "NiViEnetAsrl.dll"),
                        os.path.join("Bin", "NiViPxi.dll"),
                        os.path.join("Bin", "NiViRpc.dll"),
                        os.path.join("Bin", "NiViUsb.dll"),
                        os.path.join("NIvisa", "PxiPlugins", "NiViPpiD.dll"),
                        os.path.join("NIvisa", "PxiPlugins", "NiViPpiP.dll"),
                    ]

在运行 EXE 时，我仍然收到以下错误：OSError: Could not found VISA library. Please install VISA or pass its location as an argument.

我必须包含哪些文件/目录以及如何将其位置传递给 pyVISA 以便在 cx_Freeze 环境中运行？

这取决于您使用哪个后端。

例如，我使用带有后端 pyvisa-py 的包 pyvisa，之后您需要包含在 cx_freeze 设置文件中的文件是“visa32.dll”和包“pyvisa_py”
