我正在使用Nickolay Yegorov的port of LightBlue for OS X 10.8。导入lightblue模块后,我立即收到以下错误:

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

似乎可能存在版本不匹配。是否有针对此问题的已知修复程序?

1 个答案:

答案 0 :(得分:6)

Yegorov's repo打开源中的文件src/mac/_lightblue.py。找到第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。从此来源重新安装LightBlue:

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

这应解决签名错误。

二进制

dlamblin请求使用此修复程序的二进制文件。这是my LightAquaBlue.framework,是为OS X 10.8.2和Python 2.7.4(放在/Library/Frameworks中)而构建的。
