无法通过Conda安装bioconda频道的porechop_abi包求助

我在bioconda的GitHub仓库确认了porechop_abi包存在，但执行以下命令均出现PackagesNotFoundError：

conda install -c bioconda porechop_abi

执行搜索命令也报错：

conda search -c bioconda porechop_abi

已尝试清理并更新Conda，但问题未解决。使用-vvv选项执行安装时，关键错误日志如下：

解决思路 #

• 检查平台兼容性：bioconda部分包仅支持特定操作系统或架构。从日志看当前环境是macOS（__osx），确认porechop_abi是否提供对应版本包。若仅支持Linux，可考虑用Docker容器运行，或从源码编译安装。
• 确认bioconda频道配置：执行conda config --show channels查看频道列表，确保bioconda、conda-forge、defaults频道已添加，且bioconda顺序合理。若缺失，执行conda config --add channels bioconda、conda config --add channels conda-forge补充。
• 清理缓存并重新索引：执行conda clean -a清理所有缓存，也可手动删除macOS上的缓存目录~/anaconda3/pkgs/cache下的文件，之后运行conda update --all更新索引，再尝试安装。
• 用mamba替代conda：mamba是更高效的conda解算器，先安装mamba：conda install -n base conda-forge::mamba，再执行mamba install -c bioconda porechop_abi尝试安装。
• 源码手动安装：若上述方法无效，直接从bioconda的GitHub仓库克隆源码，按照仓库内的安装说明完成编译和安装。
