Question

当我尝试在Docker镜像中构建mxnet时，我收到以下消息：

Step 14/16 : RUN ["/bin/bash", "-c", "cd /workspace/Project/mxnet"]

---> Running in c9337d66ee5e /workspace/Project/mxnet

---> Running in 653a66e430b2 make:
*** No targets specified and no makefile found.  
Stop. The command '/bin/bash -c make' returned a non-zero code: 2

任何建议？

的问题

Step 15/16 : RUN ["/bin/bash", "-c", "make"] 
[…] The command '/bin/bash -c make' returned a non-zero code: 2

可能来自事先运行此命令的事实：

Step 14/16 : RUN ["/bin/bash", "-c", "cd /workspace/Project/mxnet"]

这是Docker中的典型错误模式。

总而言之，每个Docker RUN命令都在子shell中运行，所以如果你这样做

RUN ["/bin/bash", "-c", "cd /workspace/Project/mxnet"]
RUN other commands

其他命令不受目录更改的影响。

要解决此问题，您可以：

用

替换两行

RUN cd /workspace/Project/mxnet && other commands

或（首选解决方案）用

替换两行

WORKDIR /workspace/Project/mxnet
RUN other commands

解决方案2更具惯用性，请注意

WORKDIR /dir
RUN some command

可以在语义上看作命令

mkdir -p /dir && cd /dir && /bin/sh -c "some command"
