未正确设置HEROKU的CircleCI环境变量导致GIT失败

Question

我是 CircleCI 用户，我正在设置与 Heroku 的集成。

我想执行以下操作，并使用此 config.yml 文件通过与 dockerHub 以及从 CircleCI 门户页面到 Heroku 的集成来设置安全性。

问题在于 CircleCI 似乎不知道这些变量应该设置为什么，而只是回显。

${HEROKU_API_KEY} ${HEROKU_APP}

config.yml

问题在于 CircleCI 似乎不知道这些变量应该设置为什么，而只是回显。

${HEROKU_API_KEY} ${HEROKU_APP}

问题是为什么没有自动检测到这些设置？

Answer 1

您需要为变量设置值：https://circleci.com/docs/2.0/env-vars/

它们被回显是因为你在回显它们。

echo ${HEROKU_API_KEY}
echo ${HEROKU_APP}
