PyYaml not working

[Carlo Lozzovina]

Hi guys, I have a problem when trying to make an exe with PyInstaller
that uses PyYaml. Here is the code:

-------
import yaml

def main():
print yaml.load(open('in.yaml').read())

if __name__ == '__main__':
main()
-------

When trying to run I get this:

c:\PyInstaller\fyaml\dist\fyaml>fyaml.exe
Traceback (most recent call last):
File "<string>", line 13, in <module>
File "<string>", line 8, in main

line 93, in construct_object
File "fyaml\build\pyi.win32\fyaml\outPYZ1.pyz/yaml.constructor",
line 391, in construct_yaml_str
LookupError: unknown encoding: ascii

Any ideas how to fix this? I didn't use "--ascii" option, if that matters.

Thanks in advance.

Same thing happens even without Yaml, the simplest possible example:

------
def main():
a = "yaddayadda"
print a.encode("ascii")

if __name__ == '__main__':
main()
------

I tried adding all kinds of encodings.* imports, but nothing seems to
work.

Any help greatly appreciated.

This works with Python 2.5 and PyInstaller SVN trunk, on Windows. Which
versions are you using?

My bad, I didn't check the requirements page for PyInstaller. Any
ideas when you might support Python 2.6?

There are some patches attached to ticket #39, if you want to test them.

They don't solve the encoding problem you're seeing, though.
