Using python 3.2.3 on CentOS 6.3 cannot install or run any part of fs module #135

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Compile Python 3.2.3 on CentOS 6.3 (others may have same issue but CentOS 
6.3 is what I use).
2. Attempt to install or use any part of the fs module.

What is the expected output? What do you see instead?

Always get error message saying "ImportError: No module named errors"

What version of the product are you using? On what operating system?

I am using 0.4.0 of pyfilesystem, python 3.2.3, on CentOS 6.3

Please provide any additional information below.

Python 3 support is somewhat provisional. Please try the latest code from SVN.

Same error after I was able to get it installed since the easy_install is 
apparently not available in Python 3.

If you're looking for easy_install you need to install distribute 
http://packages.python.org/distribute/ which works on Python3.

ok, after using distribute to install it it seems to work with python 3 now, 
thanks for the help.

Great!
I'll let you do some testing, but let us know when this bug can be closed...

I spoke too soon, new error when I try to mount the filesystem. Below I am 
pasting what I used from the python commandline for testing in python 2.6.6 and 
3.2.3.

Try using the "foreground" option to mount without spawning a background 
process, this may allow more debugging or error info to be printed:

    fuse.mount(fs, "~/memory3", foreground=True)

Here is what I got when adding foreground=True.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.2/site-packages/fs-0.4.1-py3.2.egg/fs/expose/fuse/__init__.py", line 463, in mount
    return FUSE(op, path, raw_fi=True, foreground=foreground, **kwds)

    argv = (c_char_p * len(args))(*args)
TypeError: bytes or integer address expected instead of str instance

I did have one problem that I fixed, but that did not seem to change this error.

Any update on this issue?

I decided to try Python 3.3 since it is supposed to me more compatible with 
Python 2, but still got the same error. I did not really expect it to work any 
better.

Is it possible to cut a new release with the tweaks done for Python 3 
compatibility?

Currently, any modules which tries to be Python 3 compatible and try to use a 
stable release of pyfs is bound to failure since installing pyfs gives the 
error mentioned in the first post.

I'll do a minor version release. Probably at the weekend assuming there are no 
new issues or test failures.

Didn't manage the release. There are currently a few test failures.

It appears that 0.5.0 was released, apparently adding support for Python 3, and 
breaking compatibility with 0.4.0.
