standard_init_linux.go：190：exec 用户进程导致"exec format error"命令'/bin/sh -c npm install'返回非零代码：1

Question

我是docker的新手，出于我的学习目的，我遵循了官方nodejs docker指令并按照说明进行操作，但它在同一命令上不断抛出错误。

我尝试在树莓派上制作图像码头工人以用作服务器。 但是我在构建它以运行它时遇到问题

这是Dockerfile我

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

和码头工人版本

Answer 1

RUN指令有两种写作形式。

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

不幸的是，它回复了non-zero error.我们都应该知道，当错误发生时，shell脚本会回复非零错误。

我不熟悉npm.但我仍然可能会看到错误现在与 docker 无关，而是 shell 脚本本身。

也许是其他评论提到的语法或 npm 版本问题。现在与Docker平台无关。

您可以按照上面评论所述升级 npm 映像。愿这有帮助~
