当我尝试安装rails-assets-tether时，出现错误。
Retrying fetcher due to error (2/4): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for http://rails-assets.org/.
There is a chance you are experiencing a man-in-the-middle attack, but most likely your system doesn't have the CA certificates needed for verification. For information about OpenSSL certificates, see http://------/ruby-ssl. To connect without using SSL, edit y
our Gemfile sources and change 'https' to 'http'.
这是我的Gemfile的一部分：
# Bootstrap
gem 'bootstrap', '~> 4.0.0.alpha3'
source 'https://rails-assets.org' do
gem 'rails-assets-tether', '>= 1.1.0'
end
将https更改为http并不适合我。
