我尝试了什么（下面的脚本） - 我说它不起作用，因为当我将bootstrap 中的 jumbotron 示例粘贴到我的应用程序 html 文件中时，我看不到 bootstrap css“效果”。
#!/bin/bash
set -ex
rm -rf /tmp/template || true
mkdir /tmp/template
cd /tmp/template
echo "source 'https://rubygems.org'" > Gemfile
echo "gem 'rails', git: 'https://github.com/rails/rails.git'" >> Gemfile
bundle
bundle exec rails new . --force --dev --database=postgresql
perl -pi.bak -e 's/gem .rails.*/gem "rails", github: "rails\/rails"/' Gemfile
bundle install
# Devise
echo "gem 'devise'" >> Gemfile
bundle
bundle exec rails generate devise:install
bundle exec rails generate devise User
bundle exec rails generate devise:views
bundle exec rake db:drop || true
bundle exec rails db:create || true
bundle exec rails db:migrate || true
