[英]Deploying a Dash application to Heroku - dash_bootstrap_components - Error
我是 heroku 的新手，并尝试部署在本地成功运行的 Dash 应用程序。
看来“dash_bootstrap_components”是罪魁祸首。 我已确认 requirements.txt 文件中列出了“dash_bootstrap_components”。
我的控制台显示 Heroku 成功构建了应用程序，但是当我将 go 转到路径而不是加载网站时，它显示“方法不允许”。
Warning: heroku update available from 7.25.0 to 7.35.0.
