我按照以下步骤进行了安装，但是报错了，请问是什么原因呢？有没有其他办法安装qiime2呢？

请大家指教，谢谢！

1、安装anaconda3： sh Anaconda3-2019.07-Linux-x86_64.sh；

2、验证安装安装是否成功：

[...]$ conda --version
conda 4.7.10
[...]$ python
Python 3.7.3 (default, Mar 27 2019, 22:11:17) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.

3、安装qiime2

conda install -c qiime2 qiime2

conda install -c qiime2/label/2017.4 qiime2

报错
