[PEAK] Easy Install: Creating a "Virtual" Python

Hy,

I'm trying to install easyinstall without root privileges, using the
procedure described in this page:


** virtual-python.py

I downloaded the script, executed it, all is ok.

** path modification

I added this line in my ~/.bashrc:

PATH=$HOME/bin:$PATH

then took the modification into account:

bash$ source ~/.bashrc

and checked python path:

bash$ which python
/home/myname/bin/python

I also checked sys.path:

bash$ python
>>> import sys
>>> print sys.path

the output, after some formatting, is:

''
'/home/myname/lib/python2.5'
'/home/myname/lib/python2.5/plat-linux2'
'/home/myname/lib/python2.5/lib-tk'
'/home/myname/lib/python2.5/lib-dynload'
'/usr/local/lib/python2.5/site-packages'
'/home/myname/lib/python2.5/site-packages'
'/home/myname/lib/python2.5/site-packages/Numeric'
'/home/myname/lib/python2.5/site-packages/PIL'
'/home/myname/lib/python2.5/site-packages/gst-0.10'
'/var/lib/python-support/python2.5'
'/home/myname/lib/python2.5/site-packages/gtk-2.0'
'/var/lib/python-support/python2.5/gtk-2.0'


Especially, I noted thas

/home/myname/lib/python2.5/site-packages

was in sys.path

** setuptools-0.6c11-py2.5.egg

I downloaded this script on http://pypi.python.org/pypi/setuptools

and run it as:

sh setuptools-0.6c11-py2.5.egg --prefix=~

which give this error message:

TEST FAILED: /home/dfroger/lib/python2.5/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:

    /home/dfroger/lib/python2.5/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:

Please make the appropriate changes for your system and try again.


If I understand, the solutions proposed in the error message are like in the
page:

What shoud I do to get the installation via "Virtual" Python working?

Thanks for your help!

David
