Das Ausführen von Python-Skript über die Befehlszeile öffnet das Skript im Standard-Texteditor anstelle des Skripts

Question

Ich habe Dateien mit .py Erweiterung mit Python-Interpreter verbunden. Wenn ich jedoch den Namen einer solchen Datei in die Befehlszeile eintippe und ENTER drücke, wird die Datei im Standard-Texteditor (Notepad ++) geöffnet, anstatt mit dem zugehörigen Python-Interpreter ausgeführt zu werden. Warum?

Z:\1>where python 
c:\Program Files\Python\2.7\python.exe 

Z:\1>reg query HKCR\.py /ve 

HKEY_CLASSES_ROOT\.py 
    (Default) REG_SZ Python.File 


Z:\1>reg query HKCR\Python.File\shell\open\command /ve 

HKEY_CLASSES_ROOT\Python.File\shell\open\command 
    (Default) REG_SZ c:\Program Files\Python\2.7\python.exe "%1" %* 


Z:\1>echo %PATHEXT% 
.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY;.PYW 

Z:\1>type a.py 
from __future__ import print_function; import sys; print(sys.executable); print(sys.version) 
Z:\1>a.py <--- this opens a.py in the default text editor 

Ich bin auf Windows Vista x64 mit Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32

UPDATE

Nach dem Löschen HKEY_CLASSES_ROOT\Unknown\shell\notepad++\command Schlüssel (ich diesen Schlüssel in der Vergangenheit in meiner Suche erstellten Dateien mit Notepad ohne Erweiterung zu assoziieren ++ - siehe How to set the default program for opening files without an extension in Windows?), den Wert C:\Program Files (x86)\Notepad++\notepad++ %1 hatte bekomme ich diesen Fehler:

This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.

UPDATE 2

Um alle Registrierungsschlüssel angezeigt werden normalerweise durch das System verwendet, um herauszufinden, welches Programm mit .py Erweiterung zugeordnet ist, ich die folgende Batchdatei (python_assoc.query.bat) laufen:

@echo off 
if "%~1" == "details" (
    set keypath=HKLM\Software\Classes 
    echo ----- HKEY_LOCAL_MACHINE ----- 
    call :query 
    set keypath=HKCU\Software\Classes 
    echo. 
    echo ----- HKEY_CURRENT_USER ----- 
    call :query 
) else (
    set keypath=HKCR 
    echo ----- HKEY_CLASSES_ROOT ----- 
    call :query 
) 
goto end 

:query 
reg query %keypath%\.py /ve 
reg query %keypath%\.pyw /ve 
reg query %keypath%\.pyc /ve 
reg query %keypath%\.pyo /ve 

reg query %keypath%\Python.File\shell\open\command /ve 
reg query %keypath%\Python.NoConFile\shell\open\command /ve 
reg query %keypath%\Python.CompiledFile\shell\open\command /ve 
goto :eof 

:end 
set keypath= 

OUTPUT

ich auch Führen Sie Process Monitor (danke Maximus), um zu sehen, welche Registrierungsschlüssel beim Ausführen von a.py von der Befehlszeile gelesen werden. Ich habe Filter eingestellt, um nur pid von cmd.exe einzuschließen, das benutzt wird, um a.py Akte laufen zu lassen und Betriebe des Typs RegCloseKey auszuschließen.

Answer 1

Im Allgemeinen würde ich der Verein sicher nicht von außer Kraft gesetzt werden Einstellungen für den aktuellen Benutzer:

• HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\UserChoice
• HKCU\Software\Classes\.py
• HKCU\Software\Classes\Python.File

Wie ich jedoch die Process Monitor-Ausgabe in Ihrem Update gelesen habe, scheint es, dass keiner dieser HKCU Schlüssel auf Ihrem System definiert ist.

Mein nächster Schritt wäre die folgend in einer erhöhten cmd Konsole auszuführen:

> assoc .PY=Python.File 
> ftype Python.File=c:\Program Files\Python\2.7\python.exe "%1" %* 

Soweit ich weiß, dies setzt das System Verein in HKLM\Software\Classes und tut nichts anderes. Basierend auf den Informationen in Ihrer Frage scheint es, dass dies bereits korrekt eingestellt wurde. Also ich weiß nicht, was oder ftype tat, um das Problem zu beheben.

Answer 2

Kann dies helfen (machen "offen" als Standard-Verb)?

[HKEY_CLASSES_ROOT\Python.File\shell] 
@="open" 

oder diese (berücksichtigen Quoten um python.exe Pfad)?

[HKEY_CLASSES_ROOT\Python.File\shell\open] 
@="Open" 

[HKEY_CLASSES_ROOT\Python.File\shell\open\command] 
@="\"c:\\Program Files\\Python\\2.7\\python.exe\" \"%1\" %*" 

Answer 3

Kannst du nicht einfach die GUI-Methode?

„Öffnen mit ...“ -> Browse -> python.exe und tick „immer mit diesem Programm ...“

Answer 4

Ich habe seit einiger Zeit mit diesem Problem zu kämpfen, genau wie Piotr. Der Vorschlag von Eriksyn führte mich zu einem funktionierenden System.

Da Notepad2 immer meine "I-will-to-run-this" -Aufrufe geöffnet hat, muss ich etwas haben, das alle Dateien mit Notepad2 verknüpft, und jetzt wusste ich, wo ich suchen musste (Ich habe zuvor Process Monitor ausgeführt , aber die Ausgabe war zu umfangreich).

Ich habe .py Einträge mit Notepad2 Inhalt in HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts in meiner Registrierung. Ich nehme an, entweder Notepad2 hat diese selbst hinzugefügt, oder ich habe das irgendwie beim Konfigurieren der Dinge getan. Insbesondere:

Mit diesem Registrierungsschlüssel und -wert wird beim Versuch, ein Python-Skript auszuführen, Notepad2 geöffnet.

Ohne diesen Registrierungsschlüssel werden meine Python-Skripts tatsächlich ausgeführt und erfordern nicht mehr die Eingabe von "python < script>", um sie auszuführen.

Ich bin glücklich. Danke, Stapelüberlauf.
