在Docker中安装Meteor时，文件权限错误

我是Docker（2周）的新手，但是我正在为Meteor安装编写一个Dockerfile取得很好的进展。

现在我看到文件权限错误的最后一行。 老实说，我认为更广泛的问题是我不完全了解Linux文件系统和权限; 所以我会很感激任何指针。

这是错误的：

Meteor 1.5 has been installed in your home directory (~/.meteor). Writing a launcher script to /usr/local/bin/meteor for your convenience. This may prompt for your password. sudo: no tty present and no askpass program specified Couldn't write the launcher script. Please either: (1) Run the following as root: cp "/home/.meteor/packages/meteor-tool/1.5.0/mt- os.linux.x86_64/scripts/admin/launch-meteor" /usr/bin/meteor (2) Add "$HOME/.meteor" to your path, or (3) Rerun this command to try again. 

这是我运行的命令：

 docker build --build-arg user_pass=user -t timebandit/meteor-1-5 --rm . 

这是我认为是问题的Dockerfile部分：

 FROM ubuntu:xenial # update the system RUN apt-get update && apt-get -y install curl \ sudo \ apt-utils \ locales \ nano # Set the locale RUN sudo sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \ locale-gen ENV LANG en_US.UTF-8 ENV LANGUAGE en_US:en ENV LC_ALL en_US.UTF-8 # set the root password # RUN echo "root:root" | chpasswd # create a user RUN useradd -ms /bin/bash user RUN adduser user sudo RUN echo 'user:user' | chpasswd ENV HOME=/home WORKDIR $HOME # WORKDIR $HOME/user # allow writes to the home directory USER root RUN chmod 777 /home # install meteor # RUN echo $user_pass | curl https://install.meteor.com/ | sh RUN curl https://install.meteor.com/ | sh #docker build --build-arg user_pass=user -t timebandit/meteor-1-5 --rm . ARG user_pass USER user 

任何指针，你可以给我提高我对这个问题的根源的理解将不胜感激。

它看起来像meteor安装脚本要求用户input，因为你不给它，构build步骤只是失败。

这里：
This may prompt for your password. sudo: no tty present and no askpass program specified
