Thanks both advices seems to work with single python installation. With many python installations on windows: 1) does not matter in which folder you are: Is it possible to force to start certain python version (installed in forlder c:/PythonVersion) from any directory in cmd by command: c:/PythonVersion/python
2) to install module to certain python version you have to be in moduler folder there are setup,py file cmd c:/PythonVersion/pyhton setup.py install as an option parameter --home can be given, nevertheless c:/ PythonVersion/pyhton installs correctly to c:/PythonVersion/pyhton/ Lib/site-packages One more notice cmd: python do not run the pyhton version of the working folder I just find out that being in c:/first/Python26 cmd: python -- version #gives Python 2.6.5 -- EPD 6.2-2 #instead of simple Pyhton26, which i expect #I mean EPD is installed in c:/second/pythonEPD, although cmd always run this Pyhton version. #the only way to rund different pyhton version is to use command c:/ PythonVersion/python On Sep 6, 12:22 pm, Mateusz Paprocki <[email protected]> wrote: > Hi, > > On 6 September 2010 09:35, gintare <[email protected]> wrote: > > > > > > > I have several python installtions on WIndows7 > > > c:/first/Python26 > > c:/secondEPD/Python26 > > c:/Program Files (86) /Pythonxy > > > would like be able to run sympy from first > > during installation i was in c:/first/sympy-0.6.7 > > and used command python setup.py install --home='c:\\first\\Python26\ > > \Lib\\site-packages\\sympy' > > > after this sympy exists in folder given by home > > nevertheless > > c:/first/Python26> python > > >>>> import sympy, isympy > > # do not find modules > > > >>>>import imp > > >>>> imp.find_module('sympy') > > >>>>imp.find_module('isympy') > > >>>>imp.find_mofule('isympy', > > 'c:\\first\\Python26\\Lib\\site-packages\\sympy\\bin) > > # do not find modules also > > > What is wrong with installation? > > > I can use isympy, sympy from EPD. > > Still it is interesting to know how to install and use this module > > from additional python installations in the same windows7. > > You may consider modifying the PYTHONPATH shell variable.
