您会注意到在gperf选项打印输出中，“output”拼写错误。我已经尝试修改snown的setup.py以使用我能想到的所有可能的组合，-output，-ouput，-o，但它仍然只给出了用法消息。
我试过很多东西，但似乎都没用。
另外，如果有帮助的话，我使用的gperf的副本在

c:\python27\scripts\gperf.exe

最佳答案

您的系统上是否安装了python模块gperf.py？我指的是这个：https://pypi.python.org/pypi/gperf
一种检查方法：

(gperf)macbook:gperf joeyoung$ python

>>> import gperf
>>> print gperf.__file__
/Users/joeyoung/.virtualenvs/gperf/lib/python2.7/site-packages/gperf/__init__.pyc
>>> print gperf.__path__
['/Users/joeyoung/.virtualenvs/gperf/lib/python2.7/site-packages/gperf']

注意：此示例在OSX上。请使用适当的Windows命令行工具。

(gperf)macbook:gperf joeyoung$ cd /Users/joeyoung/.virtualenvs/gperf/lib/python2.7/site-packages/gperf
(gperf)macbook:gperf joeyoung$ ls -al
total 40
drwxr-xr-x   6 joeyoung  staff   204 Aug 19 04:14 .
drwxr-xr-x  14 joeyoung  staff   476 Aug 19 04:14 ..
-rw-r--r--   1 joeyoung  staff     0 Aug 19 04:14 __init__.py
-rw-r--r--   1 joeyoung  staff   184 Aug 19 04:14 __init__.pyc
-rw-r--r--   1 joeyoung  staff  7928 Aug 19 04:14 gperf.py
-rw-r--r--   1 joeyoung  staff  7656 Aug 19 04:14 gperf.pyc

我的猜测是，包含gperf.py的文件夹在您的路径中，它将被执行，而不是gperf.exe。
甚至可以在gperf.py的使用说明中看到拼写错误的ouput：

Usage: gperf.py [options]

Options:
  -h, --help            show this help message and exit
  -i INPUT_FILE, --input=INPUT_FILE
  -o OUTPUT_DIR, --ouput=OUTPUT_DIR
  --csv
  --stat
  --minor
  --height=HEIGHT
  --width=WIDTH

来源：https://pypi.python.org/pypi/gperf
如果您的系统上有pip，您可以尝试卸载gperf.py，如下所示：

pip uninstall gperf

如果幸运的话，snown'ssetup.py会在你的gperf.exe上找到你的PATH，并在gperf.py消失的情况下使用它。
编辑：对于注释中提到的错误，download this到

然后再试一次。
