相对路径导入失败，未找到模块，但绝对路径导入有效

Question

I've had this issue for a while now and tried to find fixes for it. I'm developing my discord.js bot and recently migrated from TS back to JS because of certain problems i've experienced with it. Upon migrating, however, I was met with an issue of Node.js not finding my command handler file using relative paths. VSCode resolves the path and suggests me the file, reading the directory with fs.readdir('./commands') also showed the handler file. So far I've tried:

1. Switching to dynamic import ( await import('...') ) -> didn't work
2. Removing the first part of the import ( const {... } = ) -> works
3. Commenting the handler import line off, so Node.js would import the next file -> didn't work, no imports are successful
4. Using full path to the handler file ( await import('file://C:/.../emberbot/commands/handler.js') )

Answer 1

Since relative paths are processed to the current working directory of your app, and the current working directory being a variable depending on where you start your application, its always advisable to resolve imports to the root file. This is why the absolute import works but the others fail.

Check this answer for some context

you can use __dirname

Your code becomes

fs.readdir(__dirname + '/commands')

So you code will read
