Question

我是docker的新手，出于学习目的，我遵循了官方的nodejs docker指导，并遵循了说明，但是它始终在同一命令上引发错误。

我尝试在Raspberry Pi上将图像docker用作服务器。但是我无法构建它来运行它

这是我的Dockerfile

FROM node:4.3.2
 WORKDIR /app
 RUN npm install
 EXPOSE (80)
 CMD ["node", "index.js"]

错误

 docker build -t hello-world .
Sending build context to Docker daemon  2.212MB
Step 1/5 : FROM node:4.3.2
 ---> 3538b8c69182
Step 2/5 : WORKDIR /app
 ---> Using cache
 ---> 7b8a5c56f23d
Step 3/5 : RUN npm install
 ---> Running in bbd6026d01d9
standard_init_linux.go:190: exec user process caused "exec format error"
The command '/bin/sh -c npm install' returned a non-zero code: 1

Answer 1

RUN指令有两次写入forms。

在您的情况下，您选择了shell形式的RUN语句将被解析为/bin/sh -c run-statement(npm install here)的形式。

不幸的是，它回复了non-zero error。众所周知， shell脚本会在发生错误时回复非零错误。

我对npm不熟悉。但是我仍然可以看到该错误与docker现在无关，而与shell脚本本身有关。

也许是其他注释中提到的语法或npm版本问题。现在与Docker平台无关。

您可以按照上面的评论升级npm映像。可以帮忙〜
