Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application

for all non-root users on this machine.

Warning: the running version of Bundler (1.16.1) is older than the version that created the lockfile (1.16.6). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

=======================================================

执行以上问题后 ，再次遇到 安装  ‘sass’  问题：

提示如下：

Post-install message from sass:

Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new

  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the

  sassc gem: https://github.com/sass/sassc-ruby#readme

* For more details, please refer to the Sass blog:

  http://sass.logdown.com/posts/7081811

***************************解决办法***********************************

执行：gem install sassc     （安装时长需等待几分钟哦）

再次运行 ：sudo bundle        ---安装完成

‘sassc ’参考文档：
