我在 gitlab 上的 CI/CD 使用 dpl 在 heroku 上部署代码。在获取新版本的法拉第（我想这就是原因）之前，它一直在发挥魅力。

这是我的 gitlab CI 终端（昨天）作业时的内容：

...
$ dpl --provider=heroku --app=$HEROKU_STAGING_APP --api-key=$HEROKU_API_KEY
Installing deploy dependencies
Successfully installed rendezvous-0.1.3
Successfully installed netrc-0.11.0
Successfully installed multipart-post-2.1.1

Successfully installed faraday-1.8.0
Successfully installed dpl-heroku-1.10.16
13 gems installed

这是我今天得到的：

...
$ dpl --provider=heroku --app=$HEROKU_STAGING_APP --api-key=$HEROKU_API_KEY
Installing deploy dependencies
Successfully installed rendezvous-0.1.3
Successfully installed netrc-0.11.0

Please set Faraday.default_adapter or provide one when initializing the connection.
...

我尝试将 --skip_cleanup 添加到 dpl 呼叫中，如下所示，但它不起作用。也许我可以强制重用旧版本的法拉第？但我找不到任何来源来尝试这个。
