node.js - 在Alpine Linux上安装Node.js 10 + NPM

Question

我正在使用Alpine来构建我的Rails应用程序，并且某些依赖项存在一些问题。

现在，这是我的Dockerfile:

FROM ruby:2.5.1-alpine
ENV BUNDLER_VERSION=2.0.2

RUN apk add --update --no-cache \
        binutils-gold \
        build-base \
        curl \
        file \
        g++ \
        gcc \
        git \
        less \
        libstdc++ \
        libffi-dev \
        libc-dev \ 
        linux-headers \
        libxml2-dev \
        libxslt-dev \
        libgcrypt-dev \
        make \
        netcat-openbsd \
        nodejs \
        openssl \
        pkgconfig \
        postgresql-dev \
        python \
        tzdata \
        yarn 

RUN gem install bundler -v 2.0.2
RUN mkdir /myapp
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle config build.nokogiri --use-system-libraries
RUN bundle check || bundle install

COPY . /myapp
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 80

CMD ["rails", "server", "-b", "0.0.0.0", "-p", "80"]

我的 entrypoint.sh文件如下所示:

#!/bin/sh
bundle install
rake db:migrate
rake db:seed
npm install
set -e

rm -f /myapp/tmp/pids/server.pid

exec "$@"

关于 npm install，我在尝试安装 puppeteer@3.0.0时遇到问题(由于另一个错误，无法使用3.1.0)。

这是安装3.1.0时的错误:

/myapp # npm install puppeteer@3.1.0

> puppeteer@3.1.0 install /myapp/node_modules/puppeteer
> node install.js

/myapp/node_modules/puppeteer/install.js:175
            } catch {
                    ^

基于缺乏成功安装3.1.0 here的经验，我被告知尝试3.0.0

因此，当尝试安装3.0.0时，会发生以下情况:

/myapp # npm install puppeteer@3.0.0

> puppeteer@3.0.0 install /myapp/node_modules/puppeteer
> node install.js

+ puppeteer@3.0.0

根据 this，节点版本旧。当前，我正在运行nodejs 8.9.3，如下所示:

/myapp # node -v
v8.9.3

我尝试安装 nodejs-current，但似乎已卸载了npm。

/myapp # apk add nodejs-current
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/community/x86_64/APKINDEX.tar.gz

/myapp # node -v
v9.2.1
/myapp # npm install puppeteer@3.0.0
/bin/sh: npm: not found

如何在不卸载npm的情况下升级我的nodejs版本？如果我尝试再次安装npm，则会发生以下错误:

/myapp # apk add npm
ERROR: unsatisfiable constraints:
  npm (missing):
    required by: world[npm]
/myapp # apk add --update npm
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/main/x86_64/APKINDEX.tar.gz

像在rubyfile或docker-compose.yml文件中一样，使用ruby，FROM ruby:2.5.1-alpine指定节点的所需版本，否则进行相应的设置。

检查此link以获取合适的版本。
