我在安装Conda软件包时遇到了一些问题。与其他Conda在解决源代码时滞后的问题不同，我的Conda总是在安装了所有必要的软件后滞后(至少我是这样认为的)。下面是最近的一个例子:
(DGE_smk_minimal) [name@server DGE-co-culture-workflow]$ conda install snakemake

现在它已经挂在台阶上30分钟了。有时，似乎到了列表的末尾，就像这样挂起/失败了。我已经等了30分钟了，没有任何结果，只好关闭了终端。这在上个月之前还不是问题，但现在越来越严重，已经到了失败的地步。
是否有一种方法来检查为什么会发生这种情况/一种方法来查看正在执行的子进程?作为一名科学家，我对命令行工具还是一个相对的新手。
或者，我可以运行一个清理命令使它更快吗?我真不明白为什么要花这么长时间。
您可以尝试两种方法。如果你还没有使用它，其中一个东西会改变你的性生活。
第一个简单的:有一个干净的命令你应该经常运行。conda clean -h获取更多信息。我通常只是偶尔运行conda clean --all --yes。
游戏改变者:使用曼巴代替conda*(实际上更多的是作为补充)。Mamba(https://github.com/mamba-org/mamba)是用c重写的conda。如果你已经习惯了conda的构建时间，那么Mamba将会让你大吃一惊。它是这样工作的:
1:你将mamba安装到conda base中(通常不允许在conda base中安装任何东西，但这是一个例外——Snakemake甚至公开鼓励使用它)。
conda install mamba -n base -c conda-forge
现在，继续前进，任何你想用'conda'的地方你都用'mamba'，并得到一些你的生命回报，而不是等待conda:-)——有一个例外。你仍然需要基本的conda安装&&要激活环境，仍然需要指定conda activate和conda deactivate。最重要的是，如果你错误地(或故意地)把conda和mamba互换使用，这是没有问题的——我想你不会想要的。
