由于conda的新许可政策，我们必须使用mamba作为替代。我正在迁移我的docker文件，但在正确安装micromamba时遇到了问题。基本docker如下

ARG CUDA=11.1.1
FROM nvidia/cuda:${CUDA}-cudnn8-runtime-ubuntu18.04
ARG CUDA

然后我通过apt-get安装所有curl等。

RUN curl -Ls https://micro.mamba.pm/api/micromamba/linux-64/latest | tar -xvj bin/micromamba
RUN export MAMBA_ROOT_PREFIX=./micromamba  # optional, defaults to ~/micromamba
RUN eval "$(./bin/micromamba shell hook -s posix)"
RUN micromamba activate

在构建过程中，我得到以下错误：

RUN micromamba activate
 ---> Running in ccee400f407d

'micromamba' is running as a subprocess and can't modify the parent shell.
Thus you must initialize your shell before using activate and deactivate.

    To initialize the current  shell, run:
        $ eval "$(micromamba shell hook --shell=)"
    and then activate or deactivate with:
        $ micromamba activate
    
To automatically initialize all future () shells, run:
    $ micromamba shell init --shell= --prefix=~/micromamba

Supported shells are {bash, zsh, csh, xonsh, cmd.exe, powershell, fish}.

有什么建议吗
