在 dockerfile 问题中安装 nodejs

Question

我正在尝试使用 pyenv 在 dockerfile 中安装 nodejs，但是当我运行通过我的 gitlab 运行ner 时，我一直收到此错误。我正在尝试安装版本 16.12.0。这个问题有更好的解决方案吗？

Docker 文件

#install npm
ENV NODE_VERSION=16.12.0
RUN apt install -y curl
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
ENV NVM_DIR=/root/.nvm
RUN . "$NVM_DIR/nvm.sh" && nvm install ${NODE_VERSION}
RUN . "$NVM_DIR/nvm.sh" && nvm use v${NODE_VERSION}
RUN . "$NVM_DIR/nvm.sh" && nvm alias default v${NODE_VERSION}
ENV PATH="/root/.nvm/versions/node/v${NODE_VERSION}/bin/:${PATH}"
RUN node --version
RUN npm --version

输出

一般来说，您应该避免使用像 Docker 中的 nvm 这样的版本管理器。您一次不应该需要一个以上版本的语言解释器，并且版本管理器通常需要 shell 点文件设置，这在 Docker.

中配置起来很复杂

你不说你为什么需要 Node。最简单的方法是使用 Docker Hub node image

FROM node:lts
# and none of what you show in the question

如果您使用它来构建其他 Python 应用程序的前端，您可以为此使用 multi-stage build

FROM node:lts AS frontend
WORKDIR /frontend
COPY frontend/package*.json ./
RUN npm ci
COPY frontend/ ./
RUN npm build

FROM python:3.10
...
COPY --from=frontend /frontend/dist ./static/

如果您的 Ubuntu-based 映像中确实需要 Node，那么接下来要做的最简单的事情就是安装它。 default Ubuntu nodejs package 应该可以很好地满足大多数实际用途。

FROM ubuntu:20.04
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get --no-install-recomends --assume-yes \
      nodejs

如果你真的需要在自定义镜像中使用它，并且它确实需要一个超级特定版本的 Node，你应该可以 download Node and install it.

FROM ubuntu:20.04
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get --no-install-recomends --assume-yes \
      curl \
      xz-utils
ARG node_version=v16.14.2
RUN cd /opt \
 && curl -LO https://nodejs.org/dist/${node_version}/node-${node_version}-linux-x64.tar.xz \
 && tar xJf node-${node_version}-linux-x64.tar.xz \
 && rm node-${node_version}-linux-x64.tar.xz
ENV PATH=/opt/node-${node_version}-linux-x64/bin:${PATH}
