# Cannot find module / ModuleNotFoundError / No such file or directory

**Node.js:** `Cannot find module 'MODULENAME OR FILE DIRECTORY'`

**Python:** `ModuleNotFoundError: No module named 'MODULENAME'` or `/usr/local/bin/python: can't open file '/home/container/bot.py': [Errno 2] No such file or directory`

This error usually has one of these causes:

1. Your code or startup settings look for a file in a specific directory, but the file is not there. Make sure the file exists, has no spaces before or after its name, and is in the correct directory.
2. A package required by your code is missing on the server. This usually means you did not upload the `package.json` file or did not fill in the startup field/package tab correctly. Follow [Set Up a Server](/bot-hosting.net/legacy/setup-server.md) (legacy panel) or [Set Up a Server](/bot-hosting.net/guides/set-up-a-server.md) (new panel) for the fix.
3. Another error happened first. Check the earlier console output. If you still cannot identify the root cause, open a support ticket.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bothosting-net.gitbook.io/bot-hosting.net/troubleshooting/module-directory-problems.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
