Please Note

This is not a duplicate because the other people who've got that error message all were using an external python installation instead of sage -python /path/to.py

My Situation

I'm not able to execute scripts the following ways:

• sage /path/to.sage (preprocessed)
• sage /path/to.spyx
• sage /path/to.py
• sage -python /path/to.py

But I'm able to run correctly without problems:

• sage $ load 'file'

The Traceback

When cython compiles an .spyx file:

Traceback (most recent call last):
  [...]
  File "_home_user_Dokumente_oak_code_sage_spyx_0.pyx", line 14, in init _home_user_Dokumente_oak_code_sage_spyx_0 (_home_user_Dokumente_oak_code_sage_spyx_0.c:754)
    sg.var('a b c')
AttributeError: 'module' object has no attribute 'var'

The statement that there's no var in the loaded module seems to be true because dir(sg) wasn't able to find anything else than __doc__ and other "underscored items".

When python tries to execute file (normal handwritten .py or a sage preprocessed .sage):

Traceback (most recent call last):
  File "sage2.py", line 2, in <module>
    from sage.all_cmdline import *   # import sage library
  File "/home/user/Dokumente/oak/code/sage.py", line 4, in <module>

The Question

How can I get sage -python (sage's internal python) to execute the files specified as command line argument correctly? How can I get sage.all's members to get imported correctly?
