[Jython-users] [JYTHON][EASY_INSTALL] Unable to install into custom directories.

[Subhodip B. <sub...@gm...>]

Hi all,

I am using Jython 2.5.1 for my project. I am trying to run a jython
code using the Jython-plugin of Hudson.
My jython code needs third party modules to run files. So apparently I
am trying to write a code that can install a package using
easy_install to a custom location(may be in my project tree), so that
the modules are always available.

while trying to execute the code I get this error :
----------------------------------------------------------------------------------------

Base dir My\PROJECT\
'-E' is not recognized as an internal or external command,
operable program or batch file.
TEST FAILED: My\PROJECT\site-packages does NOT support .pth files
error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

  MY\PROJECT\site-packages

and your PYTHONPATH environment variable currently contains:

  ' '

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable.  (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

  http://peak.telecommunity.com/EasyInstall.html#custom-installation-locations

Please make the appropriate changes for your system and try again.
---------------------------------------------------------------------------------------
I followed the instruction i.e created a altinstallation.pth file
which contains :

a single line import os, site;
site.addsitedir(os.path.expanduser('MY\PROJECT\site-packages'))

I have also created distutils.cfg file and have the entries :

[install]
install_lib = MY\PROJECT\site-packages

# This next line is optional but often quite useful; it directs EasyInstall
# and the distutils to install scripts in the user's "bin" directory.  For
# Mac OS X framework Python builds, you should use /usr/local/bin instead,
# because neither ~/bin nor the default script installation location are on
# the system PATH.
#
install_scripts = MY\PROJECT\site-packages\bin

But still no help. Googling also does not reveal much.
As the backslashes suggest i am on a windows machine.
In some cases i do get the python path(all default site packages and
libs) with my custom directory in the path too but with the same
error.

Where am I going wrong here?
