我无法在 Docker 容器中创建 conda 环境，尽管我可以在我的计算机中创建环境

Question

我想创建一个 Docker 容器，其中包含需要许多库的 Python 应用程序 ( Spliceai )。 这个应用程序在我的电脑上运行，所以我创建了一个 yml 文件来创建容器。 这是代码

# Define base image
FROM continuumio/anaconda3

# Set working directory for the project
WORKDIR /app

# Create Conda environment from the YAML file
COPY environment_lookup3.6.yml  .
RUN conda env create -f environment_lookup3.6.yml 

# Override default shell and use bash
SHELL ["conda", "run", "-n", "env", "/bin/bash", "-c"]

# Activate Conda environment and check if it is working properly
RUN echo "Making sure flask is installed correctly..."
RUN python -c "import pandas"

# Python program to run in the container
# COPY run.py .
ENTRYPOINT ["conda", "run", "-n", "env", "spliceai"]

这将返回以下错误

为了调试它，我使用 yml 文件创建了一个新的 env，这个工作正常。

这是我与 Docker 一起工作的第一天，尽管我一整天都在阅读和尝试，但我仍然有点困惑。 我想知道此错误的可能原因是否是由于我的 Anaconda 安装在外部驱动器上，所以在运行/bin/sh时找不到它？

这个问题类似于conda fails to create environment from yml

我刚刚从错误中检查了第一个 package

readline==8.2=hca72f7f_0

这里的格式是 package=version=build

以上 package 适用于 osx https://anaconda.org/anaconda/readline/files

我了解您正在尝试在 macosx 中创建一个 conda yaml 文件，并尝试在 docker 容器中创建相同的环境，该容器运行在基于 linux 的图像上。

您可以尝试执行以下操作并查看适合您的方法：

• 创建 yaml 文件时添加此标志 --no-builds
• 如果上述选项对您不起作用，请从类似平台（在本例中为 linux）创建 yaml 文件
