Question

我的投资组合网站在我的本地计算机上运行良好，但是当我将其上传到heroku时，出现错误：找不到模块'/app/index.js'，我搜索了论坛。所有帖子都通过不定义“开始”脚本来说明这一点。我试图修改它。所以要么我做错了，要么是另一个问题：

还请注意，我在客户端将启动命令设置为“ start”：“ node scripts / start.js”，当我将其更改为“ react-scripts start”时，我知道它是一种更好的做法- “ npm run dev”仅在服务器上运行的本地时间段。

顺便说一句，上传时我也得到这个： 远程：error-ex@1.3.2 / tmp / build_8302bae019d1d3a1f79b88a8bca2b16d / node_modules / error-ex 我找不到答案。

非常感谢所有帮手。

找不到模块“ /app/index.js”。架构或package.json问题？
