我有以下 Dockerfile
FROM jupyter/scipy-notebook
#RUN apt-get update && apt-get install -y curl
RUN pip install mlflow
RUN pip install sklearn
RUN apt-get update && apt-get install -y curl
當我做
docker build -t mycontainer .
我明白了

The command '/bin/bash -o pipefail -c apt-get update && apt-get install -y curl' returned a non-zero code: 100
我懷疑這與不以 root 身份運行有關嗎？那么如何從 Dockerfile 在我的容器中安裝 curl？
編輯：我應用了我得到的答案。不幸的是，它沒有用

EDIT2：我在不同的網路設定中嘗試過它并且它有效。
uj5u.com熱心網友回復：
嘗試apt創建/var/lib/apt/lists/partial. 這是因為您的行程沒有運行為root; 該jupyter/scipy-notebook影像被配置為以非root用戶身份運行（它以用戶身份運行jovyan）。
您可以使用指令更改運行命令的用戶Dockerfile，USER如下所示：
FROM jupyter/scipy-notebook
RUN pip install mlflow
RUN pip install sklearn
USER root
RUN apt-get update && apt-get install -y curl
USER jovyan
jovyan請注意，我已確保在運行apt-get命令后將用戶重置回。
uj5u.com熱心網友回復：
嘗試root像在官方jupyter/scipy-notebook Dockerfile中一樣安裝它并將其設定回$NB_UID：（請參閱官方基礎 docker 映像中的用戶宣告）
USER root
# Install packages you need:
RUN apt-get update && apt-get install -y curl
# Switch back to jovyan to avoid accidental container runs as root
USER $NB_UID
以下是使用的基礎 docker 鏡像的層次結構jupyter/scipy-notebook：
jupyter/base-notebook -> jupyter/minimal-notebook -> jupyter/scipy-notebook
