ruby-on-rails – docker-compose Rails弹簧不起作用

>铁路4.2.5.1运行集装箱
> Ruby 2.3.1运行机智容器

当我开始

$docker-compose exec web /bin/bash # ssh into the web server
 $bundle exec rails c

我收到以下错误.

from /usr/local/lib/ruby/gems/2.3.0/gems/bundler-1.13.1/lib/bundler/runtime.rb:86:in `each'

但是我已经把pq gem放在了Gemfile中.
我已经尝试过了,

$bundle update pg
$bundle uninstall pg && bundle install
$bundle exec spring binstub --all

但是我没有运气.

我试过的时候

$docker-compose exec web /bin/bash # ssh into the web server
$DISABLE_SPRING=1 bundle exec rails c

它确实有效.所以我认为spring gem无法正常工作.
此外,如果我在本地做同样的事情,它确实有效.

我认为我的docker_compose.yml设置不正确.
有任何想法吗？
