Docker：通过Dockerfile安装npm包时出错

这是我的Dockerfile的样子。 正如你所看到的，我正在尝试安装meteorJS，standardJS和一些npm软件包。

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，因为我不能安装npm包。

 npm WARN enoent ENOENT: no such file or directory, open '/package.json' npm WARN !invalid#1 No description npm WARN !invalid#1 No repository field. npm WARN !invalid#1 No README data npm WARN !invalid#1 No license field. npm ERR!

在开始的时候，我设置了一个非root用户，为了让meteor运行起来，必须完成这个工作。 但是，这确实使最后一行的问题…

Answer 1

答案在那里：

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

软件包正在安装在'/'

 USER ${APP_USER} 

在这里和下面的命令之间，我将把当前的工作目录更改为我希望安装的目录。

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