如果我做：

bundle exec jekyll serve

所有工作正常(_site文件夹包含必需的文件和服务器正在运行),但如果我使用以下命令：

jekyll build -d /var/www/budka/data/www/blog

我得到错误：

Dependency Error: Yikes! It looks like you don’t have jekyll-paginate
or one of its dependencies installed. In order to use Jekyll as
currently configured,you’ll need to install this gem. The full error
message from Ruby is: ‘cannot load such file — jekyll-paginate’ If
you run into trouble,you can find helpful resources at

jekyll 3.1.1 | Error: jekyll-paginate

我试图解决这个问题,但是没有成功.
现在Gemfile文件包含：

source 'http://rubygems.org'
gem 'github-pages'
gem 'html-proofer'
gem "jekyll"
gem 'jekyll-paginate'
gem "pygments.rb"

jekyll-paginate(1.1.0)gem是安装的,因为我在gem列表中看到commnad：

可以请你建议如何解决问题？
