映像run
包含已安装的npm
。尽管如此,npm install
返回错误:/bin/sh: 1: npm: not found
这怎么可能?我在做什么错了?
编辑:
作为对@BMitch注释的答复,当我运行RUN
映像时,在容器中,该节点位于PATH上,可以使用它。路径为/root/local/bin
。我已经附加了所有Dockerfile。
我有3个docker文件:

重要的是,如果我删除了RUN npm...
命令,那么整个构建都是成功的,并且结果图像包含npm并且我可以使用它(我已经以交互模式使用容器进行了验证)。>
编辑3:
这里有很多更简单的解决方案,可以立即尝试:
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
RUN cat $HOME/test.txt
结果是:cat: can't open '/root/test.txt': No such file or directory
答案 0 :(得分:2)
这里有两个问题。 “ php:7.2.5-apache”映像在路径中将没有/ root / local / bin,并且在构建期间未将其添加到路径中。当您以交互方式登录时,npm命令将起作用,这可能是由于对设置环境的Shell登录脚本进行了一些更改。在运行任何npm
命令之前,您需要运行这些环境设置脚本,并且这些操作必须在同一RUN命令中完成。为了验证自己,您可以检查.bashrc中是否存在运行npm环境的变量或命令。而且,您可以通过在交互式外壳程序和构建中将PATH值与env
命令进行比较来验证环境是否不同,如果这是您的问题,则应该看到两个不同的输出。当我运行您的一部分运行图像时,在.bashrc中看到以下内容:
export PATH=$HOME/local/bin:$PATH
因此,您需要更新Dockerfile中的运行映像行:
ENV PATH /root/local/bin:${PATH}:/home/site/wwwroot
根据您的修改3,这是一个完全不同的问题。您在一个新映像中创建了一个文件,然后返回到该文件不存在的基础映像。如果要在多阶段构建中查看文件,则需要在各阶段之间复制文件,或者将上一个图像用作“来源”。
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM alpine as img2
COPY --from=img1 /root/test.txt /root/test.txt
RUN cat $HOME/test.txt
或
FROM alpine as img1
RUN echo "$HOME" > $HOME/test.txt
FROM img1 as img2
RUN cat $HOME/test.txt
