RP4 端口上的互斥销毁失败

Question

你好，我对 Raspberry Pi 比较陌生，一直在尝试将一些最初为 Windows 编译的 Python 源代码移植到 Pi 4。我能够移植除 Win32API 之外的所有内容，我最后注释掉“import win32api”。

python 代码运行到最后一个错误处理语句，我相信它与 win32api 有关。每当我运行此代码时，我都会收到错误“python3:../../libusb/os/threads_posix.h:58: usbi_mutex_destroy: Assertion `pthread_mutex_destroy(mutex) == 0' failed。”

我追踪到的代码是：

if __name__ == '__main__':
    # vp_start_gui()
    # find_usb_port()
    root = tk.Tk()

    prog_call = sys.argv[0]
    prog_location = os.path.split(prog_call)[0]
    define.APP_LOCATION = prog_location
    file_location = os.path.join(prog_location, "./project_loc.txt")

    # Get project folder path
    f = open(file_location, 'r')
    file_loc = f.read().replace('\n', '').strip()
    f.close()
    define.ASSAY_FOLDER_PATH = str(file_loc)
    # print("define.ASSAY_FOLDER_PATH11: ", define.ASSAY_FOLDER_PATH)

    try:
        while define.ASSAY_FOLDER_PATH == "":
            define.LOAD_ASSAY_FILE = True
            resp = tkinter.messagebox.askokcancel('Select Directory for Assay files: ',
                                                  "Select a directory for Assay files and log files")

            if resp is True:
                define.ASSAY_FOLDER_PATH = filedialog.askdirectory(title='Select a directory for INT05 Project')
            else:
                root.destroy()
                sys.exit()

            # Save the log folder file to log_loc.txt to save logs
            f = open(file_location, 'w')
            f.writelines(str(define.ASSAY_FOLDER_PATH))
            f.close()
            # debug_print("define.ASSAY_FOLDER_PATH: ", define.ASSAY_FOLDER_PATH)

        client = ThreadedClient(root)
        root.mainloop()
    except Exception as e:
        # debug_print(e)
        messagebox.showerror("ERROR", "Run the app with administrative privilege... "
                                      "(This has to be done on very first run!")
        sys.exit()

运行时，GUI 会弹出“错误”、“使用管理权限运行应用程序...”语句，无论我是否以 root 身份运行代码。

任何有关我做错了什么或如何解决此错误的想法将不胜感激！我已经在这方面投入了一段时间了。

谢谢！
