【问题描述】：

这就是我的 Dockerfile 的样子。如您所见，我正在尝试安装meteorJS、standardJS 和一些npm 包。

FROM ubuntu:latest

# build arguments
ARG APP_PACKAGES
ARG APP_LOCALE=en_US
ARG APP_CHARSET=UTF-8
ARG APP_USER=app
ARG APP_USER_DIR=/home/${APP_USER}

# add packages for building NPM modules (required by Meteor)
RUN apt-get update -y
RUN apt-get -y dist-upgrade
RUN apt-get install -yqq \
        python \
        build-essential \
        apt-transport-https \
        ca-certificates \
        curl \
        locales \
        nodejs \
        npm \
        nodejs-legacy \
        sudo \
        git
RUN apt-get autoremove
RUN apt-get clean
RUN rm -rf /var/lib/apt/lists/*

# set the locale (required by Meteor)
RUN locale-gen ${APP_LOCALE}
RUN localedef ${APP_LOCALE}.${APP_CHARSET} -i ${APP_LOCALE} -f ${APP_CHARSET}

# create a non-root user that can write to /usr/local (required by Meteor)
RUN useradd -mUd ${APP_USER_DIR} ${APP_USER}
RUN chown -Rh ${APP_USER} /usr/local
USER ${APP_USER}

# MeteorJS
RUN curl https://install.meteor.com/ | sh
# StandardJS
RUN npm install -g standard
# NPM packages
RUN npm install gridfs-stream gm fluent-ffmpeg

但最后一行似乎有一些问题，因为我无法安装 npm 包。

npm WARN enoent ENOENT: no such file or directory, open '/package.json'

一开始我设置了一个非root用户，必须这样做才能让meteorJS工作。但这确实给最后一行带来了问题......

【问题讨论】：

也许，您忘记了-g 选项？
旁注：我推荐使用官方节点镜像node:8.6，而不是使用ubuntu:latest。

标签： ubuntu docker meteor npm

【解决方案1】：

答案就在那里：

Error: EACCES: permission denied, access '/']

软件包正在安装在“/”中

USER ${APP_USER}

在此处和以下命令之间，我会将当前工作目录更改为我希望安装它的位置。

# MeteorJS
RUN curl https://install.meteor.com/ | sh
# StandardJS
RUN npm install -g standard
# NPM packages
RUN npm install gridfs-stream gm fluent-ffmpeg
