当我开始构建过程时，安装了sprockets-3.6.2。
我的Dockerfile：
# Use the barebones version of Ruby 2.2.3.

# Optionally set a maintainer name to let people know who made this image.
MAINTAINER Class and Objects <classandobjects@gmail.com>
# Install dependencies:
RUN apt-get update && apt-get install -qq -y build-essential nodejs libpq-dev postgresql-client-9.4 --fix-missing --no-install-recommends
# Set an environment variable to store where the app is installed to inside
# of the Docker image.
# CHANGE ALL INSTANCE OF 'backend' WITH YOUR PROJECT NAME
ENV INSTALL_PATH /backend
RUN mkdir -p $INSTALL_PATH
# This sets the context of where commands will be ran in and is documented
# on Docker's website extensively.
WORKDIR $INSTALL_PATH
# Ensure gems are cached and only get updated when they change. This will
# drastically increase build times when your gems do not change.
COPY Gemfile Gemfile
RUN bundle install
# Copy in the application code from your work station at the current directory
# over to the working directory.
COPY . .
# Provide dummy data to Rails so it can pre-compile assets.

答案 0 :(得分：1)
卷正在屏蔽图像中的目录。
volumes:
- .:/backend
您正在使用当前目录中的文件覆盖容器路径/backend，这意味着您在bundle install期间安装的所有依赖项都不再存在。
您应该删除该卷，或运行docker-compose run backend bundle install以获取主机上的依赖关系。
