Re: [pydicom] SyntaxError: invalid syntax during install

[Jonathan Suever]

Rickard,

First of all, welcome to Python! 

So the issue that you're having is that when you run the "python" command you're running the system python, which for Scientific Linux 4.6 is version 2.3.4. Pydicom requires version 2.6 or higher. We have a legacy fork which can be used with earlier versions.

Did you install python 3.3 from source? If you want to use python 3,  you probably need to run either python3 or python3.3 (python3 setup.py install). Is there any particular reason that you are using Python 3.3? I ask because currently, python 3.x is not officially supported in pydicom. I'm actually currently trying to track down a bug that appears during installation on python3.3 installations.

I would strongly recommend sticking to python 2.7 for now. It is still widely used and most packages should support it. If you have to use python 3 for some reason, I'd recommend any version 3.2 or below.

Hi folks,

I'm a MATLAB user that is considering learning python. My only python experience is the mandatory hello world test so please consider that when laughing at my ignorance.

To the point: I'm trying to install pydicom under Linux (Scientific Linux 4.6) using python 3.3.0. This is what I get
[root@rf-cluster pydicom-0.9.8]# python setup.py install
Traceback (most recent call last):
  File "setup.py", line 2, in ?
    from distribute_setup import use_setuptools
  File "/usr/local/python/pydicom-0.9.8/distribute_setup.py", line 248
    @_no_sandbox
    ^
SyntaxError: invalid syntax

The distribute_setup.py looks like this from line 248:

@_no_sandbox
def _rename_path(path):
    new_name = path + '.OLD.%s' % time.time()
    log.warn('Renaming %s into %s', path, new_name)
    os.rename(path, new_name)
    return new_name

Any pointers? Any at all?

Best regards,
Rickard

Thanks for your reply Jonathan.

There was no particular reason for installing python 3.3, I just grabbed the latest version I could find. I was not aware of the distinction between python and python3. Just installed python 2.7.3 and pydicom installed without issues. Win!
