【问题描述】：
我有一个在本地运行的 express 应用，现在是时候在 Heroku 上部署到生产环境了。但是在开始时，在构建之后，我得到了这个错误。

我不知道这些错误是否相关。
我已经尝试重建...我在 package.json 中丢失了一些包，修复了这些...删除了未使用的包，几乎所有内容。我什至两次删除了该应用程序并在 Heroku 上重新开始，但运气不好。这是我的 package.json。

我被难住了。
【问题讨论】：
-
app.js中有什么内容？ -
@Chris 我编辑了问题以包含 app.js 的内容
-
除了“退出状态1”之外没有其他相关输出了吗？我建议您在代码中添加一些日志记录输出。在 Heroku 上，您打印到
stdout或stderr的任何内容都将被捕获到日志流中。 -
@Chris 感谢您的快速回复！我应该在哪里注销？我什至无法辨别错误的位置。我认为它必须对 npm 和我的依赖项做一些事情
-
啊，这里有更多信息。您完全确定您向我们展示了正确的
package.json吗？看起来dynamic-url-constructor没有安装在 Heroku 上。在出现错误之前，您是否看到它已安装在您的部署输出中？
