Trouble Installing and Importing SendKeys — Update

问题

I am trying to install SendKeys for Python.

If I use

pip install SendKeys

I get a link error:

 _sendkeys.c(150): warning C4013: 'Py_InitModule' undefined; assuming extern returning int 
 C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\link.exe /nologo /INCREMENTAL:NO /LTCG /DLL /MANIFEST:EMBED, \10.0.10240.0\ucrt\x64" "/LIBPATH:C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6.1\lib\um\x64" "/LIBPATH:C:\Program Files (x86)
LINK : error LNK2001: unresolved external symbol PyInit__sendkeys

error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1120

If I download the 64-bit .whl and try to install it with pip locally I get:

sendkeys-0.3-cp27-none-win_amd64.whl is not a supported wheel on this platform.

I get the same error if I try the 32-bit version.

pip is up to date. Is there something wrong with my Visual Studio setup?

--Update--

I was able to intall SendKeys after updating the Python module in Visual Studio, but I get the following error when I try to import SendKeys

>>> import SendKeys
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\...\AppData\Continuum\Anaconda3\lib\site-packages\sendkeys-0.3-py3.5-win-amd64.egg\SendKeys.py", line 419
    except (ValueError,AssertionError),e:

SyntaxError: invalid syntax

The code that throws the error is in main:

def main(args=None):
 import getopt

 if args is None:
    args = sys.argv[1:]

 try:
    opts,args = getopt.getopt(args, 
        "hp:d:f:", ["help","pause","delay","file"])
 except getopt.GetoptError:
    usage()

 pause=0
 delay=0
 filename=None

 for o, a in opts:
    if o in ('-h','--help'):
        usage()
    elif o in ('-f','--file'):
        filename = a
    elif o in ('-p','--pause'):
        try:
            pause = float(a)
            assert pause >= 0
        except (ValueError,AssertionError),e:
            error('`pause` must be >= 0.0')
    elif o in ('-d','--delay'):
        try:
            delay = float(a)
            assert delay >= 0
        except (ValueError,AssertionError),e:
            error('`delay` must be >= 0.0')

 time.sleep(delay)
                                  ^

回答1:

The installation error was caused by missing components of Visual Studio, and was fixed by updating the Python Tools for Visual Studio. That's probably a common problem for installation and updates on Windows.

I still have not fixed the import issue. I think it has to do with the python version, but I'm not sure. In any event, I've chosen to use pyautogui instead, so the issue is moot.

Download .zip file, unzip and do python setup.py install
