我想运行一个带有奇点的 conda 命令。命令是：
singularity exec ~/dockerimage.sif conda
它产生一个错误：
/.singularity.d/actions/exec: 9: exec: conda: Permission denied
这是我的码头文件：
FROM ubuntu:20.04
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y apt-utils wget=1.20.3-1ubuntu1 python3.8=3.8.2-1ubuntu1.2 python3-pip=20.0.2-5ubuntu1 python3-yaml=5.3.1-1 git=1:2.25.1-1ubuntu3
RUN wget https://repo.anaconda.com/miniconda/Miniconda3-py38_4.8.3-Linux-x86_64.sh && chmod +x Miniconda3-py38_4.8.3-Linux-x86_64.sh && ./Miniconda3-py38_4.8.3-Linux-x86_64.sh -b && cp /root/miniconda3/bin/conda /usr/bin/conda
RUN wget https://data.qiime2.org/distro/core/qiime2-2020.8-py36-linux-conda.yml && conda env create -n qiime2-2020.8 --file qiime2-2020.8-py36-linux-conda.yml && conda install -y -n qiime2-2020.8 -c conda-forge -c bioconda -c qiime2 -c defaults q2cli q2template q2-types q2-feature-table q2-metadata vsearch snakemake
我应该在 Dockerfile 中添加什么？它将如何运作？
