从 cmd 运行时，.py 文件在文本编辑器中打开

Question

Whenever I try to run a .py file from cmd it opens up in a text editor(np++). I'm trying to run the following:

django-admin.py startproject testprj

Even if I run 'setup.py install'

Answer 1

You need to change the file association so that .py files open with Python executable, typically located in C:\\Python<version>\\ and not Notepad++

Changing this should be easy, but here is how to do it.

Also, read here on to set the environment path so that the Python executable is found without you having to navigate to C:\\Python2.6.

Answer 2

Your Windows file associations are set to open .py files in a text editor. You have to change those to use the python.exe interpreter, or you can prefix all your commands with python, like this:

python django-admin.py startproject testprj

If you want to change your file associations, and you are running Vista or Windows 7, you can change them in 'Control Panel'->'Default Programs'->'Associate a file type or protocol with a program'

Answer 3

It is very easy: `python (or directory to python.exe with python.exe on the end) filename (Or a again directory to the file with the name and extension on the end.) any arguments.

So if i would want to run setup.py on my desktop: I could eather:

use cd to get all the way to the folder where the .py file is

and then

"pathtopythonwithoutnameonend\python.exe" (In "!) setup.py 

or

python  "pathtofolderinwhichsetup.pyiswithoutname\setup.py" (In "!)

It is that easy. Seriously.
