Question

I tried to run Google App Engine development server using Python 3.2 and Python 2.7, got errors on both:

Python 2.7:

D:\nCdy\WA>C:\Python27\python.exe "D:\Program Files\Google\google_appengine\dev_
appserver.py" wa.py
Traceback (most recent call last):
  File "D:\Program Files\Google\google_appengine\dev_appserver.py", line 76, in

    ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal
not in range(128)

Python 3.2:

D:\nCdy\WA>C:\Python32\python.exe "D:\Program Files\Google\google_appengine\dev_
appserver.py" wa.py
Traceback (most recent call last):
  File "D:\Program Files\Google\google_appengine\dev_appserver.py", line 76, in

    run_file(__file__, globals())
  File "D:\Program Files\Google\google_appengine\dev_appserver.py", line 72, in
run_file
    execfile(script_path, globals_)
NameError: global name 'execfile' is not defined 

How do I run it?

Answer 1

It won’t work with Python 3.2.

I’ve had no trouble with GAE and Python 2.7 on Windows 7. It will soon be the officially supported version.

Right now, the officially supported version is Python 2.5, so you should download that if you have any problems getting other versions to work.

I’d suggest something like ActiveState since there are no official binaries for the latest version of Python 2.5.
