我正在尝试按照this tutorial在Python 3.7和2.7的Anaconda2提示符下安装deeptools。
首先，我遇到了一个环境错误，可以通过运行以下命令解决该问题：
$ conda create --name dianaenv python=2.7
$ conda activate dianaenv
$ conda config --add channels bioconda
$ conda install -c bioconda deeptools
但是现在运行最后一个conda install时出现以下错误：
The error: 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. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: / Found conflicts!

我还尝试单独安装需求并安装numpy，scipy和matplotlib。一切都很好。但是，当我尝试安装py2bit，pybigwig或pysam时，也会出现以下错误：
$ pip install py2bit

此外，如果我尝试使用pip install，则会收到以下matplotlib错误：

我尝试卸载并重新安装anaconda和其他软件包，但是它不起作用。
Q ：安装deeptools时如何解决UnsatisfiableError？
答案 0 :(得分：0)
从vs2008_runtime来看，这是Windows系统，但是Bioconda仅支持Unix和Linux。此外，deeptools要求deeptools-intervals，它也仅支持Unix和Linux。
我不使用Windows，但是我听说过Windows Linux子系统（WSL）的好处。这样，您可以安装Linux版本的Conda（如this article中所述）。尽管为了科学研究，我强烈建议安装Miniconda而不是Anaconda。
