xlrd module problems
Miguel Angel
i have been using Pyinstaller to freeze a program in Windows for some time
now, i have just upgraded xlrd module (http://pypi.python.org/pypi/xlrd) and the
last version (0.7.6) have this line in __init__.py:
__VERSION__ = open(path.join(path.dirname(__file__), 'version.txt')).read().strip()
and the corresponding file in C:\Python27\Lib\site-packages\xlrd\version.txt
with "0.7.6" as the only content, now my program fails after freeze with this error:
Traceback (most recent call last):
File

IOError
[Errno 2] No such file or directory:
'c:\\gestion_financiera\\build\\pyi.win32\\gestion_financiera\\outPYZ1.pyz\\version.txt'
I have collected datafiles before but i don't know how to collect a file and put
it inside the outPYZ1.pyz archive, and i am not sure that putting directly there
a file with a common name like "version.txt" would be a good idea anyway, i
suppose i should be doing anything else.
In the meantime i have changed the xlrd __init__.py to '__VERSION__ = "0.7.6"'
but don't seems to me like a good idea keep modifying modules sources to get my
application freeze correctly.
What should i do? Thanks.

This will simply not work with a frozen app. Please see the manual for
hot to adopt for being frozen.

Even if you'd add the file to the PYZ, the line above will not work:
open() can not open content within an archive (no matter if PYZ or zip
or something else).

Best solution is to contact the author so he will change his code. (IMHO
Reading the version number from an external file is no good idea anyway.)
