应用程序错误 - 部署到 Heroku 后我收到一条错误消息，即使我的应用程序在开发中运行良好

Question

我尝试将我的应用发布到 Heroku，但收到以下错误消息：

应用程序发生错误，无法提供您的页面。如果您是应用程序所有者，请查看您的日志以获取详细信息。您可以在 Heroku CLI 中使用以下命令完成此操作

heroku 日志 --tail

我检查了日志并获得了以下我无法破译的信息：

(node:40446) SyntaxError Plugin: heroku: /home/me/.local/share/heroku/config.json: Unexpected end of JSON input

知道出了什么问题吗？在本地主机中一切正常，但现在即使在本地部署后我也遇到了问题。

Answer 1

有一个拼写错误。替换

const path = requier("path");

与

const path = require("path");

并再次部署它以查看它是否有效。
