Question

我读过Raspberry Pi能够传输FM。我已下载脚本并放在目录＆＃34; / home / pi /＆＃34;。然后我在终端上通过putty执行了以下命令：

pi@raspberrypi ~ $ sudo python
Python 2.7.3 (default, Mar 18 2014, 05:13:23)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PiFm
>>> PiFm.play_sound("left_right.wav")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "PiFm.py", line 7, in play_sound
call(["./pifm", filename])
File "/usr/lib/python2.7/subprocess.py", line 493, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied

我确保声音文件＆＃34; left_right.wav＆＃34;在同一目录中。我不知道为什么会抛出这个错误。

我使用Raspbian作为操作系统，如果这很有意思......
