在国内安装QIIME2

---

Step 1：给conda换清华源

修改用户目录下的 .condarc 文件的内容为

channels:
  - defaults
show_channel_urls: true
default_channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  qiime2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

参考 https://mirror.tuna.tsinghua.edu.cn/help/anaconda/

Step 2：下载最新yml文件并修改channels

wget https://data.qiime2.org/distro/core/qiime2-2021.8-py38-linux-conda.yml

打开文件，修改channels中的qiime2/label/r2021.8为qiime2

参考 https://docs.qiime2.org/2021.8/install/native/

Step 3：安装

conda env create -n qiime2-2021.8 --file qiime2-2021.8-py38-linux-conda.yml
