I am using Windows 8 where I have Python 2.7 installed. In addition I have cygwin installed where I installed also Python 2.7.
I need to install a Python library whose installation on Windows is not supported but it is on Linux so I want to try to use it on Cygwin.
The library has a "configure" script who checks dependencies for many packages and settings and complaints because some python packages are not installed.
But when I try to install them, the system says they are installed. From this, I have concluded that my python windows installation is overlapping my python cygwin installation.
I think that the cygwin is importing in the Path all the windows Path and while the script checking the configuration can find the cygwin installation, when executing from the command-line it is not the case.
Of course, I don't want to remove from the PATH my windows python.
My question is then, what option do I have to work from cygwin only with the cygwin python installed? As far as I have seen in other questions, usually the problem is the opposite (making cygwin to use windows python, what is problematic and not recommended in some cases).
Set the path in your .profile then.
So if e.g. your Python is in C:\Python27
remove the windows paths to /cygdrive/c/Python27 in .profile
E.g.:
$ echo $PATH
/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:
/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:
/usr/bin:/cygdrive/c/Program Files/Microsoft SQL Server/110/Tools/Binn:/bin:/cygdrive/c/Python27:
/cygdrive/c/Python27/Scripts
=>
.profile:
export PATH=/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:
/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:
/cygdrive/c/Program Files/Microsoft SQL Server/110/Tools/Binn
