该图像run
包含一个已安装的npm
. 尽管如此,npm install
返回错误:/bin/sh: 1: npm: not found
这怎么可能?我究竟做错了什么?
编辑:
作为对@BMitch 评论的回答,当我运行RUN
图像时,容器中的节点位于 PATH 上,我可以使用它。路径是/root/local/bin
。我已经附上了所有的 Dockerfile。
我有 3 个 docker 文件:

重要的是,如果我删除RUN npm...
命令,那么整个构建成功并且结果图像包含 npm 并且我可以使用它(我已经通过在交互模式下使用容器进行了验证)。

这里有很多更简单的解决方案,可以立即试用:
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
RUN cat $HOME/test.txt
结果是:cat: can't open '/root/test.txt': No such file or directory
