I'm trying out Oracle Enterprise Linux 5 - basically a clone of RHEL - and trying to get sqlpython installed on it. OEL5 comes with Python 2.4; sqlpython 220.127.116.11 needs Python 2.5. I could take out the 2.5 dependency in sqlpython, but it uses pyparsing. Pyparsing dropped 2.4 compatibility as of 1.5.2.
[EDIT: It turns out that pyparsing 1.5.2 still works on Python 2.4. It emits a scary error message, during easy_install under Python 2.4 -
except ParseException as err:
SyntaxError: invalid syntax
but it installs successfully nonetheless. Thanks to Paul McGuire to pointing that out. So my job in this case is simply to release a 2.4-compatible sqlpython 18.104.22.168.]
I could change
install_requires=['pyparsing==1.5.1']in setup.py, but that locks everybody into an obsolete pyparsing whether they need it or not.
I'd like to
install_requires=(['pyparsing>=1.5.1'] if python.version >= '2.5' else ['pyparsing==1.5.1']), but that's absolutely imaginary syntax.
Obviously, I could just download a newer Python and install it on my machine, but I'm trying to make sqlpython usable for DBAs who don't have that kind of authority, or who fear to muck around with their environment that way.
I wonder what the smart people do in situations like this?
