安装PyAudio用于跨平台的distutilscross问题

Question

When I installed PyAuduo for my MIPS embedded platform, I got this error:

 running build
 Traceback (most recent call last):

   AttributeError: '_Environ' object has no attribute 'has_key'

It seems "crosscompile.py" cannot run python3 normally. Does anyone have idea how to modify the code in crosscompile.py to work normally in pyhton3?

Answer 1

how to solve AttributeError: '_Environ' object has no attribute 'has_key'

It seems like PyAudio was built in Python 2x. Python 2x had support for has_key() function to check if keys existed in dictionaries. In Python 3x, you simply do this:

if 'the_key' in os.environ:

You can potentially change this line in crosscompile.py as a quickfix and then contact the developer ( http://people.csail.mit.edu/hubert/pyaudio/#contact ).
