Command line prompt broken on XP with Python 2.5 - help!
My last version of Python was 2.4, running smoothly on XP with path c: \Python24 - no need even to include this path in PATH; everything worked as it's supposed to at the command line. Just installed Python 2.5, after uninstalling 2.4 (and also 2.3 which had lingered). Now if I open a shell in Windows Python is not available! Here are the symptoms: - If I open a shell using "Command line here" with XP Powertools, then enter "python" at the prompt, nothing happens. I don't get a message that the command is not recognized, but neither do I get the Python prompt. Instead the Windows prompt comes back. No messages, no Python, no nothing. - If I go so far as to specify the full path to the Python executable, I do get the Python prompt and Python appears to work properly - except that I can't exit with CTRL-Z. - If I open a shell from the Start menu, e.g. Start > run "command", then try entering "python", the shell simply blows up. What is going on here? I have uninstalled and reinstalled Python 2.5, to no avail. I have gone so far as to specify c:\Python25 (the install path) in my PATH variable, but this makes no difference. Right now Python is unusable to me from the command prompt, meaning all of my automation scripts that I run at the command line are gone too. -- http://mail.python.org/mailman/listinfo/python-list

I've already added the new python to my path in this fashion, but to no avail. Besides, if it were a path problem in the usual sense, the symptom would be a message at the command line saying that "python" is not recognized. Since I don't get this message, it's not a typical path problem. What it is, I don't know - that's my quandry. -- http://mail.python.org/mailman/listinfo/python-list

It's a cygwin problem, guddammit. I was wondering if this might be the case - I should have mentioned in my initial post that I've got a whole Cygwin setup, including Python. I know the conflict is the problem because just now I opened up a command shell in XP (not the Cywgin bash window), and instead of typing "python" and getting nothing, I tried "which python" - which when you think about it, shouldn't even work in a XP shell. But somehow Cygwin is mingling some of its capabilities with the XP shell, because "which python" actually gets an answer - "/usr/bin/python," which is Cygwin. Now the question is how to fix this - I don't want to uninstall the Cygwin version. Instead I need some way of unknotting Cygwin's intrusion into what should be an XP-only shell, or else a way of giving priority when in that shell (and not the bash shell, which I also use) to the Python executable residing at C:\Python25. -- http://mail.python.org/mailman/listinfo/python-list

For the moment I've moved c:\cygwin to the end of my path, so that it comes after c:\Python25, and reinstalled Python 2.5. That seems to have cured at least this particular problem with Python. When I have a spare moment I will take cygwin out of the path altogether and see if I can remember why I put it in there to begin with ... -- http://mail.python.org/mailman/listinfo/python-list

Okay - here is from the Cygwin manual available online at http:// cygwin.com/cygwin-ug-net/cygwin-ug-net.html: "The PATH environment variable is used by Cygwin applications as a list of directories to search for executable files to run. This environment variable is converted from Windows format (e.g. C:\WinNT \system32;C:\WinNT) to UNIX format (e.g., /WinNT/system32:/WinNT) when a Cygwin process first starts. Set it so that it contains at least the x:\cygwin\bin directory where "x:\cygwin is the "root" of your cygwin installation if you wish to use cygwin tools outside of bash." -- http://mail.python.org/mailman/listinfo/python-list

Having looked at the Cygwin user manual, I think I probably did this as the result of misunderstanding the installation process. A PATH variable is needed, but it can go into cygwin.bat. -- http://mail.python.org/mailman/listinfo/python-list
