使用mamba替换conda和anaconda配置环境安装软件

使用mamba替换miniconda和anaconda，原因是速度更快，无论是创建新环境还是激活环境

conda、mamba、anaconda都是蟒蛇的意思…

下载mambaforge

wget https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-Linux-x86_64.sh
bash Mambaforge-Linux-x86_64.sh

linux和mac使用命令行下载mambaforge

curl -L -O "https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-$(uname)-$(uname -m).sh"

windows版本和linux、mac版本可以从夸克网盘下载

安装

windows直接鼠标双击打开Mambaforge-Windows-x86_64.exe文件在图形界面安装；

linux和mac在命令行中安装

bash Mambaforge*.sh

• 设置镜像

linux和mac在${HOME}目录下新建文件.condarc

Windows中默认路径为C:\Users\用户名\.condarc

always_yes设为true， 也不用每次加-y参数或者每次手动输入y确认安装包了。

always_yes: true
show_channel_urls: true
channels:
  - defaults
default_channels:
  - https://mirror.sjtu.edu.cn/anaconda/pkgs/r
  - https://mirror.sjtu.edu.cn/anaconda/pkgs/main
custom_channels:
  conda-forge: https://mirror.sjtu.edu.cn/anaconda/cloud/
  pytorch: https://mirror.sjtu.edu.cn/anaconda/cloud/
  bioconda: https://mirror.sjtu.edu.cn/anaconda/cloud/

创建一个简单环境

创建一个名叫fastq_env的环境，包括一个软件fastqc

mamba create -n fastq_env -c bioconda fastqc

创建一个单细胞分析环境

示例创建一个Python单细胞分析环境；
