Я получаю эту ошибку, когда я генерирую новое приложение направляющих

Fetching source index from https://rubygems.org/
Retrying source fetch due to error (2/3): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for rubygems.
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 bit.ly/ruby-ssl. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.

         run  bundle exec spring binstub --all

Я работал gem update --system, но это не работало. Я снизился с другой ошибкой:

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

Что продолжается здесь и как я могу зафиксировать его?Спасибо
