解决步骤 #

• 安装/重装fmt库：错误核心是缺失libfmt.9.dylib，直接安装对应依赖：

  brew install fmt
  

  若已安装，执行重装确保文件完整：

  brew reinstall fmt
  

• 验证库路径并修复链接：

  1. 查看fmt的安装路径，确认是否为错误中指定的/opt/homebrew/opt/fmt：

     brew --prefix fmt
     

  2. 若路径存在但系统仍无法找到，临时添加库路径到环境变量：

     export DYLD_LIBRARY_PATH=/opt/homebrew/opt/fmt/lib:$DYLD_LIBRARY_PATH
     

     如需永久生效，将上述命令添加到~/.zshrc或~/.bash_profile文件末尾，然后执行source ~/.zshrc（或对应shell配置文件）。

• 重新编译安装danmakuC：预编译的danmakuC二进制包可能存在依赖路径问题，强制从源码编译安装：

  pip uninstall -y danmakuC
  pip install --force-reinstall --no-binary :all: danmakuC
  

• 重装bilix确保依赖匹配：

  pip install --force-reinstall bilix
