【中文标题】没有名为“websockets.legacy”的模块

【英文标题】：No module named 'websockets.legacy'

【问题描述】：

我正在尝试使用 auto-py-to-exe 构建一个 exe。 exe构建成功，但现在我的websocket服务器 程序不工作。 如果有人知道这个问题的解决方案，请告诉我。

代码：

import asyncio
import websockets
import win32gui
import win32ui
import win32con
import win32com.client
import win32api
import json
from PIL import Image, ImageFile
import io
import time

shell = win32com.client.Dispatch('WScript.Shell')

ImageFile.MAXBLOCK = 2**20

def left_click(pos_x, pos_y):
  win32api.SetCursorPos((pos_x, pos_y))
  win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, pos_x, pos_y, 0, 0)
  win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, pos_x, pos_y, 0, 0)

def right_click(pos_x, pos_y):
  win32api.SetCursorPos((pos_x, pos_y))
  win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTDOWN, pos_x, pos_y, 0, 0)
  win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP, pos_x, pos_y, 0, 0)
    
async def echo(websocket, path):
 while True:
    try:
        raw_data = await websocket.recv()
        data = json.loads(raw_data)
        if data['type'] == 'click':
            pos_x = data['x']
            pos_y = data['y']
            if data['click_type'] == 1:
              left_click(pos_x, pos_y)
            elif data['click_type'] == 2:
              left_click(pos_x, pos_y)
              left_click(pos_x, pos_y)
            elif data['click_type'] == 3:
              right_click(pos_x, pos_y)
            else:
              pass
        if data['type'] == 'keydown':
            cmd = ''
            
            if data['shiftKey']:
              cmd += '+'

            if data['ctrlKey']:
              cmd += '^'

            if data['altKey']:
              cmd += '%'

            if len(data['key']) == 1:
              cmd += data['key'].lower()
            else:
              cmd += ''+data['key'].upper()+''

            shell.SendKeys(cmd)
    except websockets.ConnectionClosed as exc:
        pass
    except Exception as ex:
        pass
    try:
        PREV_IMG = None
        hdesktop = win32gui.GetDesktopWindow()

        width = win32api.GetSystemMetrics(win32con.SM_CXVIRTUALSCREEN)
        height = win32api.GetSystemMetrics(win32con.SM_CYVIRTUALSCREEN)
        left = win32api.GetSystemMetrics(win32con.SM_XVIRTUALSCREEN)
        top = win32api.GetSystemMetrics(win32con.SM_YVIRTUALSCREEN)

        # device context
        desktop_dc = win32gui.GetWindowDC(hdesktop)
        img_dc = win32ui.CreateDCFromHandle(desktop_dc)

        # memory context
        mem_dc = img_dc.CreateCompatibleDC()

        screenshot = win32ui.CreateBitmap()
        screenshot.CreateCompatibleBitmap(img_dc, width, height)
        mem_dc.SelectObject(screenshot)

        bmpinfo = screenshot.GetInfo()

        # copy into memory 
        mem_dc.BitBlt((0, 0), (width, height), img_dc, (left, top),win32con.SRCCOPY)

        bmpstr = screenshot.GetBitmapBits(True)

        pillow_img = Image.frombytes('RGB',
          (bmpinfo['bmWidth'], bmpinfo['bmHeight']),
          bmpstr, 'raw', 'BGRX')
        with io.BytesIO()as image_data:
            pillow_img.save(image_data, "JPEG", quality=80, optimize=True, progressive=True)
            image_data_content = image_data.getvalue()

        if image_data_content!= PREV_IMG:
            await websocket.send(image_data_content)
        PREV_IMG = image_data_content
        mem_dc.DeleteDC()
        win32gui.DeleteObject(screenshot.GetHandle())

    except websockets.ConnectionClosed as exc:
        pass
    except Exception as ex:
        pass

    

async def main():
  async with websockets.serve(echo, "", 9999):
    await asyncio.Future()  # run forever

asyncio.run(main())

这个程序是为rdp和vnc做的，它使用websockets成为一个服务器，然后客户端可以通过连接它来访问计算机。

【问题讨论】：

请修剪您的代码，以便更容易找到您的问题。请按照以下指南创建minimal reproducible example。

【参考方案1】：

转到高级并添加隐藏的导入 (websockets.legacy) 直到成功。您可能还需要添加其他隐藏的导入（找不到的那些）
