Windows 8.1上的Pyusb-无后端可用-如何安装libusb? [英] Pyusb on windows 8.1 - no backend available - how to install libusb?
问题描述
正在使用pyinstaller 3.1，python 2.7.9和tkinter.
Working on pyinstaller 3.1, python 2.7.9, and tkinter.
尝试使用pyusb代替pyserial，但没有可用的后端.调查 Windows上的Pyusb-无后端可用， Python中的USB接口，依此类推，看来我需要安装libusb.但是，当我在python下运行"import usb"和"import usb.core"时，没有错误.我不知道如何在项目中安装它以及如何在项目中使用它，如何告诉我的项目libusb在哪里.
Try to use pyusb instead of pyserial, but no backend available. Looking into Pyusb on windows - no backend available, PyUSB ValueError: No backend available, USB interface in Python, and so on, it seems that I need to install libusb. But when I run "import usb" and "import usb.core" under python, no errors. I have no idea how to install it and how to use it in my project, how to tell my project where libusb is.
我做了什么:
(1)下载libusb-win32-bin v1.2.6.0(01/17/2012)
(1) download libusb-win32-bin v1.2.6.0 (01/17/2012)
(2)x86 \ libusb0_x86.dll重命名为libusb0.dll
(2) x86\libusb0_x86.dll renamed to libusb0.dll
(3)在64位上，将其放入Windows \ syswow64 \ libusb0.dll. 在32位上，安装到Windows \ system32 \ libusb0.dll.
(3) On 64 bit, put it to Windows\syswow64\libusb0.dll. On 32 bit, Installs to Windows\system32\libusb0.dll.
仍然无法正常工作...
Still not working...
顺便说一句，我想完成一个基于Python的独立Windows应用程序.我不希望其他人安装libusb来运行我的应用程序.该怎么办?
By the way, I would like to finish one standalone python-based windows app. I do not hope others to install libusb to run my app. What to do?
推荐答案
我从此处下载了最新的libusb Windows二进制文件: http://sourceforge. net/projects/libusb/files/libusb-1.0/libusb-1.0.20/libusb-1.0.20.7z/download 然后我根据以下信息复制了libusb1.dll:在64位Windows上， 必须将MS64 \ dll \ libusb-1.0.dll复制到C:\ Windows \ System32并 (用于运行使用libusb的32位应用程序) 必须将MS32 \ dll \ libusb-1.0.dll复制到C:\ Windows \ SysWOW64. 然后我将libusb1.lib从二进制文件复制到python目录中的lib dir，现在pyusb对我有用.希望能帮助到你.
I downloaded latest libusb windows binaries from here: http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.20/libusb-1.0.20.7z/download then I copied libusb1.dll according to this: when you are on 64-bit Windows, MS64\dll\libusb-1.0.dll must be copied into C:\Windows\System32 and (for running 32-bit applications that use libusb) MS32\dll\libusb-1.0.dll must be copied into C:\Windows\SysWOW64. and then I copied libusb1.lib from binaries to lib dir in python directory and now pyusb works for me. hope it helps.
