【问题描述】：

我正在尝试使用节点 12.18.4 的 alpine 版本创建节点红色 docker 映像，但出现以下错误

我的 docker 文件中的内容

FROM node:12.18.4-alpine as builder
RUN mkdir -p /root/.node-red
WORKDIR /root/.node-red
COPY package.json .
RUN npm install -g --unsafe-perm node-red
CMD ["node-red"]

我的 package.json 文件的内容

{
    "name": "node-red",
    "description": "sample",
    "version": "0.0.1",
    "dependencies": {
        "node-red": "^1.2.9"
    }
}

如何解决 python 依赖问题，将此类映像部署到生产环境会产生什么后果。任何帮助表示赞赏，谢谢！

更新：按照建议修改json文件后，出现以下错误

node-pre-gyp ERR! node -v v12.18.4

后来我修改了我的 docker 文件为

FROM node:12.18.4-alpine as builder
RUN mkdir -p /root/.node-red
WORKDIR /root/.node-red
COPY package.json .
RUN apk update && apk add python && apk add g++ make
RUN npm install -g --unsafe-perm node-red
CMD ["node-red"]

在构建 docker 映像时使用上述 json 文件出现以下错误

【问题讨论】：

标签： node.js docker npm

【解决方案1】：

图像缺少python解释器，您需要安装它。之后你也会错过 c/c++ 工具，所以你也需要安装它们。

RUN apk update && apk add python alpine-sdk

所以 dockerfile 看起来像这样

FROM node:12.18.4-alpine as builder
RUN mkdir -p /root/.node-red
WORKDIR /root/.node-red
COPY package.json .
RUN apk update && apk add python alpine-sdk
RUN npm install -g --unsafe-perm node-red
CMD ["node-red"]

【讨论】：

感谢您的快速回复，我在尝试您的建议后修改了问题，请您看看。
这是来自编译 c/c++ 库的警告。尝试容器中的节点红色，它对我有用。
抱歉，我没有完全理解您所说的“从容器中尝试节点红色”的意思。
您已经构建了映像（请与docker image ls 核对。如果是，请从其中启动一个容器并测试您的应用程序。除非有其他错误，否则警告不会阻止安装。
是的，上述警告/错误并没有阻止安装，映像正在成功部署，我想知道是否有办法修复这些警告/错误，谢谢。
