安装Python库Omnizart时遭遇Build Wheel错误求助

我在安装Omnizart库时反复碰到Getting requirements to build wheel ... error错误。已经单独执行pip install ffmpeg fluidsynth pysoundfile安装了依赖，也多次安装Cython，但还是提示ModuleNotFoundError: No module named 'Cython'，尝试用虚拟环境也解决不了。完整错误日志如下：

可行的解决办法 #

• 强制在安装Omnizart前确保Cython已安装，执行以下命令：

  pip install cython && pip install omnizart
  

• 检查pip环境一致性：确认安装Cython和Omnizart用的是同一个pip。Windows下用where pip，Linux/macOS用which pip查看路径，同时用pip --version确认版本，避免系统pip和虚拟环境pip混淆。
• 升级核心工具后再安装：

  pip install --upgrade pip setuptools wheel cython
  pip install omnizart
  

• 虚拟环境下操作：激活虚拟环境后，先装Cython再装Omnizart，以Windows虚拟环境为例：

  venv\Scripts\activate
  pip install cython
  pip install omnizart
  

• 源码安装：克隆仓库后手动安装Cython再执行本地安装：

  git clone https://github.com/Music-and-Culture-Technology-Lab/omnizart.git
  cd omnizart
  pip install cython
  pip install -e .
