Github证书未在macports中验证

Question

我正在尝试安装ros-hydro-genmsg，但遇到以下错误。

--->  Attempting to fetch 0.4.23-0.tar.gz from https://github.com/ros-gbp/genmsg-release/archive/release/hydro/genmsg/

DEBUG: Fetching distfile failed: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

当我在任何浏览器中手动转到该链接时，会立即下载该文件。当试图通过macports下载它时，它不接受证书？我已将“DigiCert High Assurance EV Root CA＆gt; SSL”和“GTE Cyber​​Trust Global Root＆gt; SSL”置于始终如同其他地方建议的信任，但这也无效。
