Question

我尝试使用PyBluez在树莓派上运行低功耗蓝牙示例。

所有示例都需要使用gattlib模块。我收到错误

from gattlib import *
ImportError: No module named gattlib

我尝试安装它：

pip3 install gattlib

但这不起作用吗？我无法安装gattlib？

编辑：这是安装gattlib时的输出：

pi@raspberrypi:~ $ pip3 install gattlib

Answer 1

我也有这个。我认为这里似乎缺少一些依赖项：

https://bitbucket.org/OscarAcena/pygattlib/src/a858e8626a93cb9b4ad56f3fb980a6517a0702c6/DEPENDS?at=default&fileviewer=file-view-default

对我来说，即使安装了它们，我也无法成功安装。我使用了一个替代软件包：

pip3 install pygattlib

Answer 2

先安装这些依赖：

pkg-config
libboost-python-dev
libboost-thread-dev
libbluetooth-dev >= 4.101
libglib2.0-dev
python-dev

然后，对于 gattlib 和 python3，试试：

pip3 download gattlib
tar xvzf ./gattlib-0.20150805.tar.gz
cd gattlib-0.20150805/
sed -ie 's/boost_python-py34/boost_python-py35/' setup.py
pip3 install .

为Pybluez安装GATTlib？
