Question

我安装了Python 3.5.2（4def2a2901a5）64位和pywin32 v.220。

当我尝试从PyWin窗口运行COM浏览器时，出现以下错误：

Failed to execute command:
from win32com.client import combrowse;combrowse.main()
Traceback (most recent call last):
  File "C:\Program Files\Python35\lib\site-packages\win32com\client\gencache.py", line 60, in __init__

    f = open(os.path.join(win32com.__gen_path__, "dicts.dat"), "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Program Files\\Python35\\lib\\site-packages\\win32com\\gen_py\\dicts.dat'

During handling of the above exception, another exception occurred:

    f = open(fname,"w")
PermissionError: [Errno 13] Permission denied: 'C:\\Program Files\\Python35\\lib\\site-packages\\win32com\\gen_py\\__init__.py'

我该如何解决这个问题？

您想获取有关您使用的com-ports的信息吗？你的问题并不清楚......

如果＆＃34;是＆＃34;，您也可以简单地

    import serial.tools.list_ports

    def scan_comports(self):        
        correct_port = 'none'
        ports = list(serial.tools.list_ports.comports())
        for p in ports:
              print "%s %s"%(p[0], p[1])
              if str(p[1]).startswith("SomeComportName"):
                 correct_port = p[0]

因为我不知道并且从不需要＆＃34; win32com.client＆＃34; 用于python中的comport操作我无法帮助这个模块（这对我来说无关紧要，因为comports是串行端口。。）
