OS X 10.8上的LightBlue:方法签名不匹配

Question

我在OS X 10.8上使用Nickolay Yegorov的LightBlue端口。在导入lightblue模块后，我立即得到以下错误:

Traceback (most recent call last):
  File "commander.py", line 3, in <module>
    import lightblue
  File "/usr/local/lib/python2.7/site-packages/lightblue/__init__.py", line 160, in <module>
    from _lightblue import *
  File "/usr/local/lib/python2.7/site-packages/lightblue/_lightblue.py", line 397, in <module>
    class _AsyncDeviceInquiry(Foundation.NSObject):
TypeError: Error when calling the metaclass bases
    class _AsyncDeviceInquiry does not correctly implement protocol IOBluetoothDeviceInquiryDelegate: the signature for method deviceInquiryComplete:error:aborted: is v@:@iB instead of v@:@iZ

看起来可能是版本不匹配。这个问题有已知的修复方法吗?

Answer 1

打开Yegorov的repo源代码中的src/mac/_lightblue.py文件。查找467行(如下所示):

deviceInquiryComplete_error_aborted_ = objc.selector(
    deviceInquiryComplete_error_aborted_, signature="v@:@iB")

将字符串v@:@iB修改为v@:@iZ。从这个源代码重新安装LightBlue:

cd <lightblue_root> && sudo python setup.py install

这将解决签名错误。

二进制

dlamblin请求了一个带有此修复的二进制文件。这是我的LightAquaBlue.framework，用Python 2.7.4构建于OS X 10.8.2(放入/Library/Frameworks)。
