我很难用Heroku部署一个在本地工作而没有任何问题的react/webpack应用程序。当我尝试部署它时，会得到一个以"Build failed with error code:1"one_answers"error:failed to push some refs to"结尾的大文本字符串https://git.heroku.com/vast-wildwood-63128.git'"。我真的不确定问题是从哪里来的，所以我已经附上了我的server.js和package.json，如果我缺少任何有用的信息，请告诉我。不确定它是否相关，但通常我使用Linux，但最近我一直在使用Windows。谢谢
edit：更新包json，引擎字段为建议的

您需要在package.json中指定节点版本，这样Heroku就知道要运行哪个节点版本。
例如
"engines": {
"node": "8.x|10.x"
},
https://devcenter.heroku.com/articles/nodejs-support
读取指定node.js版本部分的内容。
