如何解决Herokuproblem 推送问题:错误:无法将一些引用推送到“https://git.heroku.com/wwwwwww.git”
我正在尝试将我的 Rails 应用程序推送到 Heroku,但它一次又一次地向我显示此错误。有什么问题?

我运行了 heroku login
和 heroku create
,在完成一些步骤后,我运行了 git push heroku main
并出现了此错误。我也试过 git push heroku main: main
,但这并没有改变任何东西。然后我创建了一个分支,然后例如 dev
然后我运行了 git push heroku dev:main
但它再次失败。
解决方法
这与您如何推动 main
无关。创建一个分支并在推送时明确命名远程分支将无济于事。
仔细查看错误信息:

Ruby 2.7.0 不受支持,但如果您访问 the page mentioned in the error message,您应该会看到版本 2.7。3 受支持(在撰写本文时)。
Update your Gemfile
accordingly、提交和重新部署。
