各位道友，是否遇到过此问题，可否帮忙看看？ 开发环境： Ubuntu 24.04 Ruby 3.0.4 OpenSSL 3.0.13 30 Jan 2024 (Library: OpenSSL 3.0.13 30 Jan 2024) 搞过：export SSL_CERT_FILE=/path/to/cacert.pem（无效）

执行：bundle install 提示： Fetching source index from https://gems.ruby-china.com/

Retrying fetcher due to error (2/4): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for https://gems.ruby-china.com/. 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 https://railsapps.github.io/openssl-certificate-verify-failed.html. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.
