pyflakes script not executable on Windows

[Jason R. Coombs]

Pyflakes script is installed on Windows without any extension. As a result, on Windows, it has no file type and cannot be executed from a command-line. Consider using setuptools console_script entry_points or adding a .py extension when installing under Windows.

I get this trying to use pyflakes on Windows (Python 2.6 - windows 7 - pyflakes 0.4.0):

C:\My Dropbox\RoboRally\RoboRallyIronPython
> pyflakes MyBrain.py
Traceback (most recent call last):
  File "C:\Python26\Scripts\pyflakes.py", line 3, in <module>
    from pyflakes.scripts.pyflakes import main
  File "C:\Python26\Scripts\pyflakes.py", line 3, in <module>
    from pyflakes.scripts.pyflakes import main
ImportError: No module named scripts.pyflakes

That is after installation with easy_install. Using pip it doesn't install an executable script for Windows at all.

[Sorin Sbarnea (ssbarnea)]

In fact pyflakes doesnt install an executable at all on windows. It must install a pyflakes.bat with the following content

@echo off
rem Use python to execute the python script having the same name as this batch
rem file, but without any extension, located in the same directory as this
rem batch file
python "%~dpn0" %*

I have 22 other scripts following the same recipe, or you could try to comeone with an pyflakes.exe but I'm sure it's not what you want.

[Lorenzo Bolognini (lbolognini)]

The fix for this is super easy. Just rename the Scripts\pyflakes file something like runpyflakes also if it had an extension it would be nice.
