Node.js 安装节点10+；alpine linux上的npm

我正在使用Alpine构建我的Rails应用程序，我对它的一些依赖项有一些问题

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 "$@"

当涉及到

npm安装时

，我在尝试安装

puppeteer@3.0.0

（由于另一个错误，无法使用3.1.0）

以下是安装3.1.0时出现的错误：

/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 {
                    ^

由于安装3.1.0没有成功，我被告知尝试3.0.0

因此，在尝试安装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

(node:111) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): The "original" argument must be of type function

+ puppeteer@3.0.0
added 4 packages in 1.264s

根据，节点版本是旧的。目前，我正在运行nodejs

8.9.3

，如下所示：

/myapp # node -v
v8.9.3

我试图安装nodejs current，但似乎它卸载了npm

如何在不卸载npm的情况下升级我的nodejs版本？如果我再次尝试安装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
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:

    required by: world[npm]

在Dockerfile或docker-compose.yml文件中为节点指定所需的版本，与使用ruby时一样，

来自ruby:2.5.1-alpine

，否则相应地。

检查此项以获得合适的版本。

您需要使用更新版本的

ruby

，它具有升级版本的

alpine内核。例如，您可以使用
ruby:2.5.3-alpine3.9

FROM ruby:2.5.3-alpine3.9
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 \
        npm \
        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

和少量命令的输出

/ # npm -v
6.4.1
/ # node -v
v10.14.2
/ # cat /etc/issue

Kernel \r on an \m (\l)


如果您更改这些
复制Gemfile/myapp/Gemfile
，该怎么办，
COPY Gemfile.lock/myapp/Gemfile.lock
然后
WORKDIR/myapp
@sachithmuhandram发生同样的事情。在
Dockerfile
中添加
apk add npm
怎么样？我得到
错误：不可满足的约束：
运行时出错@sachithmuhandram，节点如何适应这个应用程序堆栈否则呢？您是否可以使用多阶段构建来基于
节点：lts
图像组装前端，然后
将其复制到最终应用程序中？
