Node.js 未在Heroku上加载快速自定义模块

请参阅下面的更新

我已经用Express编写了一个Node.js应用程序，它在本地运行得很好，但是当我在Heroku上运行该应用程序时，会出现以下错误：

由于下面的建议，我已经运行了heroku run bash，以了解实际存在的文件，当我执行以下操作时，我发现了一些有趣的信息，即我尝试导入的文件实际上不存在：

---

看起来我没有在app/blog和app/addressbook中上传这些文件。很有趣，这是一条很好的信息。感谢您的建议……

根据您提供的信息，这可能就是答案。在mac终端中（我假设您正在运行OSX的屏幕截图中），从blog.js文件所在的文件夹运行此命令

file blog.js -I

这应该告诉您该文件的mime类型为“text/plain”，如果返回的mime类型为“text/x-c”，则该文件看起来像是最初在Linux上创建的-这是您的问题

要简单地解决这个问题：

• 创建一个新文件
• 将blog.js的内容复制到
• git rm旧文件
• 重命名新文件
• 获取并添加新文件

新文件现在应该具有mime类型“text/plain”。将更改推送到Heroku并进行测试

如果这不是问题，我的下一步将是运行：

heroku run bash

并查看该文件是否存在于应用程序希望在Heroku上找到的位置。如果您仍然有问题，请发回这些调查的结果

让我知道

参考资料：

奇怪的行为；尝试使用以下工具进行调试：

console.log( __dirname );

确保以下路径正确（指向blog.js文件）：

然后尝试显式地将其传递给

require

：（可能会根据

\uuu dirname

返回的内容而有所不同..）

---

在我看来，该应用程序运行的工作目录与您在Heroku上预期的不同。

process.cwd（）

的值是多少？@myanimal但是只要

app.js

和

blog.js

在同一个目录中，它就可以正常工作。你是对的！这是一个

text/x-c

git rm blog.js

返回的

pathspec'blog/blog.js'与任何文件都不匹配

。我可以把它移到垃圾箱吗？您可能需要运行

git rm blog/blog.js

，但是可以将它移到垃圾箱。重要的是确保您的包含是mime类型

text/plain

。创建一个新文件，并将旧文件的内容复制到其中，然后使用

file blog.js-I

命令确保新文件的类型为

text/plain

，然后添加并提交，然后推送到Heroku。不知道如何创建非text/plain的文件。每当我创建一个新文件时，它总是将其创建为text/x-c。可能是.js扩展名？嗨，Brad，这真的很奇怪，但是如果删除下面的注释块（第75:84行），您会注意到文件现在报告为“text/plain”。为什么会这样是另一个问题！不是为我做的。还有其他想法吗？以下是日志：
