我的应用程序在后端使用Symfony 4开发，在前端使用React js开发，然后我希望将其部署在Heroku上。我已经将heroku与我的github存储库连接了。最后，在完成所有配置后，我启动了命令git push heroku master，然后发现以下错误：
git push heroku master

有人可以给我任何解决方案或建议吗？谢谢
似乎您已在bundles配置中启用了TwigBundle，但由于某种原因未在composer.json文件中进行设置。尝试重新安装树枝包：
composer req twig
或如果不需要，请从config/bundles.php中删除TwigBundle。
