Question

在Linux上使用Anaconda，我尝试了以下操作：

 conda install -c bioconda figtree

但这给了我

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

也许只是我一个人，但这不是没有帮助的信息吗？ Output in format: Requested package -> Available versions是什么意思？他们只是想刻薄吗？

我不是要在其他地方搜索答案吗？在这里提出要求并不正确

最重要的是：我将来如何解决这个问题和类似问题？带有或不带有Anaconda

Answer 1

Bioconda具有channel configuration settings，用户需要遵循{concept {3}}才能从Bioconda软件包中获得预期的行为，包括解决安装问题。特别是，用户应具有 conda-forge > bioconda > 默认值。这可能是影响安装的原因，因为figtree具有xorg-libxtst作为依赖项，并且仅在Conda Forge上。

如果您想执行 ad （如OP中那样），则模仿其推荐设置的命令将是

conda install --override-channels -c conda-forge -c bioconda -c defaults figtree

通道顺序定义其优先级。

但是，通常最好在全局（Bioconda文档显示）或在每个环境（针对具有多个项目的用户）下进行配置：

# activate environment conda activate my_env # set channels for environment conda config --env --add channels defaults conda config --env --add channels bioconda conda config --env --add channels conda-forge # no need to use ad hoc `-c` flags conda install figtree

康达安装Figtree
