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snudown的setup.py以使用我能想到的所有可能的组合，--output，--output，-o，但它仍然只给我提供用法消息。

我尝试了很多方法，但似乎都不能正常工作。

另外，如果有用的话，我正在使用的gperf副本位于

c:\python27\scripts\gperf.exe

你的系统上安装了python模块gperf.py吗？我指的是这个：https://pypi.python.org/pypi/gperf

检查的一种方法是：

(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']

Window注意：此示例是在OS X上。使用适当的命令行工具。

(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

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

用法: gperf.py选项选项：-h，-i显示此帮助消息并退出-i INPUT_FILE，-h=输入文件宽度，--OUTPUT= OUTPUT_DIR --csv --OUTPUT_DIR --minor --height=HEIGHT --width=WIDTH

来源：https://pypi.python.org/pypi/gperf

如果您的系统上有pip，您可以尝试像这样卸载gperf.py：

pip uninstall gperf

如果我们幸运的话，snudown的setup.py会在你的PATH上找到你的gperf.exe，并在gperf.py消失的情况下使用它。

download this：对于注释中提到的错误，编辑到

然后再试一次。
