本地部署AI小智：Opus 音频库没有正确安装

raise Exception(“Could not find Opus library. Make sure it is installed.”)
Exception: Could not find Opus library. Make sure it is installed.

解决：
https://ftp.osuosl.org/pub/xiph/releases/opus/opus-1.5.2.tar.gz

解压文件，创建“build”文件

cmd用管理员打开终端输入：cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON
提示cmake为安装，那么就要安装

https://cmake.org/download/

下载好后，双击安装:

再运行：cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON

再安装：cmake --build . --config Release

记住这个路径：D:\AIoT/dayb\opus-1.5.2\Release\opus.dll

修改文件：
根据报错的信息找到文件
我的是这里：D:\exploit\anaconda\az\envs\xz\Lib\site-packages\opuslib_next\api\init.py

打开“init.py” （可以先备份文件）

修改成我这样：
#!/usr/bin/env python

“”“OpusLib Package.”“”

print(f"Loading Opus library from: {lib_location}")
libopus = ctypes.CDLL(lib_location)

c_int_pointer = ctypes.POINTER(ctypes.c_int)
c_int16_pointer = ctypes.POINTER(ctypes.c_int16)
c_float_pointer = ctypes.POINTER(ctypes.c_float)

这样重新启动没有问题：
