问题：

Traceback (most recent call last):
  File "E:\An3\lib\site-packages\psutil\_pswindows.py", line 716, in wrapper
    return fun(self, *args, **kwargs)
  File "E:\An3\lib\site-packages\psutil\_pswindows.py", line 873, in kill
    return cext.proc_kill(self.pid)

During handling of the above exception, another exception occurred:

代码：

def get_process_list():
    '''获取当前进程'''
    process_list = []
    for proc in psutil.process_iter():
        process_list.append(proc)
    return process_list

def picture_kill(process_list):
    '''和之前的进程比较，若有新进程则关闭'''
    for proc in psutil.process_iter():
        if not proc in process_list:
            proc.kill()

def get_product_screenshot(html):
    '''截图并保存图片'''
    process = get_process_list()
    img = ImageGrab.grab((445,195,1467,872))
    img.show()
    number = get_order_number(html)
    path = 'E:\python\京东'
    path1 = path + '\\' + number
    path2 = path1 + '\\' + number + '.jpg'
    if not os.path.exists(path):
        os.makedirs(path1)
    img.save(path2)
    picture_kill(process)

PermissionError: [WinError 5] 拒绝访问。
关闭进程的时候提是没有权限，看看是不是进程已经不存在了或者权限不够
用os.exec("taskkill 你的进程")试试看
