导入.dll -s

我有一个Kivy应用程序，它必须连接到物理设备。连接和控制设备的代码已经写入.dll文件。所以我想从.dll文件导入一些函数。导入.dll -s

我设法导入它在Python中。下面是它的代码：

mydll.py：运行将返回[ 'COM3'， 'COM4']

import clr 

# import dll-s 
try: 
    clr.AddReference("CETAx10_x15") 
    clr.AddReference("Converter") 
    clr.AddReference("NLog") 
    clr.AddReference("ValueDefine") 
    clr.AddReference("Python.Runtime") 
except: 
    clr.AddReference("cls\\CETAx10_x15") 
    clr.AddReference("cls\\Converter") 
    clr.AddReference("cls\\NLog") 
    clr.AddReference("cls\\ValueDefine") 
    clr.AddReference("cls\\Python.Runtime") 

import CETAx10_x15 
import Converter 
import NLog 
import ValueDefine 
import Python.Runtime 
import System 


def get_openports(): 

    temp = [] 
    output = [] 

    ports_reply = CETAx10_x15.CETA.get_ports(temp) 

    for elem in ports_reply[1]: 
     output.append(elem) 

    return output 

print(get_openports())

，所以它做什么它应该。

我的Kivy应用程序运行完美无需导入此mydll.py文件。正如你所看到的[“COM3”，“COM4”]被打印出来

：我Kivy应用程序导入此mydll.py将返回以下错误消息。

我的应用程序和“mydll.py”都像一个魅力。但导入后将失败。

我只是不明白为什么两个独立工作的程序在导入后失败。

我使用： Win7的蟒蛇3.4 Kivy 1.9.2.devs0（公布：22.02）

设法解决它。我添加下面一行：

从导入库进口进口

到文件：

C：\ Python34 \ LIB \站点包\ kivy \ factory.py
