OS X 10.8上的LightBlue :方法签名不匹配

Question

我用的是Nickolay Yegorov的port of LightBlue for OS X 10.8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

看起来可能存在版本不匹配。是否有已知的解决此问题的方法？

Answer 1

从Yegorov's repo的源代码中打开文件src/mac/_lightblue.py。查找第467行(如下所示)：

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

将字符串v@:@iB更改为v@:@iZ。从以下来源重新安装LightBlue：

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

这应该可以解决签名错误。

二进制

dlamblin请求使用此修复程序的二进制文件。下面是my LightAquaBlue.framework，它是使用Python2.7.4为OSX10.8.2构建的(放在/Library/Frameworks中)。
