   - 确保 `opuslib` 相关库正确安装。

2. **Linux/macOS**

   - 运行以下命令安装 `libopus`:
     ```sh
     sudo apt-get install libopus-dev  # Ubuntu/Debian
     brew install opus                 # macOS
     ```

## 2. `externally-managed-environment` (macOS)

### **错误描述**

```
(.venv) huangjunsen@huangjunsendeMac-mini py-xiaozhi % pip install -r requirements_mac.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a Python library that isn't in Homebrew,
    use a virtual environment:
    
    python3 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3 -m pip install xyz
    
    If you wish to install a Python application that isn't in Homebrew,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. You can install pipx with
    
    brew install pipx
    
    You may restore the old behavior of pip by passing
    the '--break-system-packages' flag to pip, or by adding
    'break-system-packages = true' to your pip.conf file. The latter
    will permanently disable this error.
    
    If you disable this error, we STRONGLY recommend that you additionally
    pass the '--user' flag to pip, or set 'user = true' in your pip.conf
    file. Failure to do this can result in a broken Homebrew installation.
    
    Read more about this behavior here: <https://peps.python.org/pep-0668/>

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
```

### **解决方案**

1. **使用虚拟环境安装**
   ```sh
   python3 -m venv my_env
   source my_env/bin/activate
   pip install -r requirements.txt
   ```
2. **使用 **``** 进行全局安装**
   ```sh
   brew install pipx
   pipx install package_name
   ```
3. **强制安装（不推荐）**
   ```sh
   pip install package_name --break-system-packages
   ```

## 3. `WebSocket连接失败: BaseEventLoop.create_connection() got an unexpected keyword argument 'extra_headers'`

### **错误描述**

```python
# 建立WebSocket连接
self.websocket = await websockets.connect(
    self.WEBSOCKET_URL, 
    extra_headers=headers # 高版本这里改为 additional_headers=headers
)
```

### **解决方案**

- **新版本 **``: `extra_headers` 改为 `additional_headers`。
- **旧版本 **``: `additional_headers` 改为 `extra_headers`。

## 4. `没有找到默认的输入/输出音频设备`

### **错误描述**

```
AudioCodec - ERROR - 初始化音频设备失败: [Errno -9996] Invalid input device (no default output device)
AudioCodec - WARNING - 无法初始化音频设备: [Errno -9996] Invalid input device (no default output device)
```

### **解决方案**

1. **Windows**:

   - 在 **声音设置** 中启用麦克风和扬声器。

2. **Linux/macOS**:

   ```sh
   pactl list sources | grep "Name"
   ```

3. **检查可用音频设备**:

   ```python
   import pyaudio
   p = pyaudio.PyAudio()
   for i in range(p.get_device_count()):
       print(f"设备 {i}: {p.get_device_info_by_index(i)['name']}")
   ```

4. **手动指定音频设备**:

   ```python
   stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, input_device_index=0)
   ```

## **5. `ModuleNotFoundError: No module named '_tkinter'` mac m4以下常见 ** 

### **错误描述**
```
(.venv) apple@appledeMac-mini py-xiaozhi % python main.py

Traceback (most recent call last):
  File "/Users/apple/Desktop/py-xiaozhi/main.py", line 5, in <module>
    from src.application import Application
  File "/Users/apple/Desktop/py-xiaozhi/src/application.py", line 23, in <module>
    from src.display import gui_display, cli_display
  File "/Users/apple/Desktop/py-xiaozhi/src/display/gui_display.py", line 2, in <module>
    import tkinter as tk
  File "/opt/homebrew/Cellar/python@3.12/3.12.9/Frameworks/Python.framework/Versions/3.12/lib/python3.12/tkinter/__init__.py", line 38, in <module>
    import _tkinter  # If this fails your Python may not be configured for Tk
    ^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named '_tkinter'
```

### **解决方案**

1. **安装 `tcl-tk`**
   ```sh
   brew upgrade tcl-tk # 一般第一步就可以了
   ```

2. **检查 Homebrew 的 `tcl-tk` 路径**
   ```sh
   brew info tcl-tk
   ```

3. **重新安装 Python，并链接 `tcl-tk`**
   ```sh
   brew install python-tk
   ```

4. **手动指定 `Tcl/Tk` 路径（如有必要）**
   ```sh
   export PATH="/opt/homebrew/opt/tcl-tk/bin:$PATH"
   export LDFLAGS="-L/opt/homebrew/opt/tcl-tk/lib"
   export CPPFLAGS="-I/opt/homebrew/opt/tcl-tk/include"
   ```

5. **重新创建虚拟环境**
   ```sh
   python3 -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt
   ```

## 6. `导入 opuslib 失败: No module named 'pyaudioop'或'_cffi_backend'`

### **错误描述**

```
找到opus库文件: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows\opus.dll
已添加DLL搜索路径: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows
已成功加载 opus.dll: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows\opus.dll
导入 opuslib 失败: No module named 'pyaudioop'
确保 opus 动态库已正确安装或位于正确的位置
```

或

```
找到opus库文件: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows\opus.dll
已添加DLL搜索路径: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows
已成功加载 opus.dll: D:\xiaozhi\PC\py-xiaozhi-main\libs\windows\opus.dll
导入 opuslib 失败: No module named '_cffi_backend'
请确保 opus 动态库已正确安装或位于正确的位置
```

### **解决方案**

1. **Python版本兼容性问题**
   - 这个错误通常与Python版本有关，尤其是Python 3.13版本
   - 建议使用Python 3.9-3.12版本

2. **重新安装cffi**
   ```sh
   pip uninstall cffi
   pip install cffi
   ```

3. **opus.dll放置**
   - 确保已将opus.dll放在正确位置（项目根目录和System32目录）
   ```sh
   # 检查是否已复制到这些位置
   C:\Windows\System32\opus.dll
   项目根目录\opus.dll
   项目根目录\libs\windows\opus.dll
   ```

4. **安装pyaudioop支持库**
   - 对于'pyaudioop'错误，尝试降级Python版本或安装相关依赖
   ```sh
   pip install pyaudio
   ```

```

### **解决方案**
- 建议python版本在 3.9 - 3.12

1. **确保 `numpy` 版本兼容**

   `numpy==2.0.2` 可能存在构建问题，建议尝试安装较稳定的版本：
   ```sh
   pip install numpy==1.24.3
   ```

   如果你不需要特定版本，可以安装最新稳定版本：
   ```sh
   pip install numpy
   ```

2. **安装编译工具**
   
   Windows用户可能需要安装Visual C++ Build Tools：
   ```sh
   # 安装Microsoft C++ Build Tools
   # 下载并安装: https://visualstudio.microsoft.com/visual-cpp-build-tools/
   ```

3. **使用预编译的轮子**
   ```sh
   pip install --only-binary=numpy numpy
   ```
