# 언어 옵션을 babel로 변경했더니 이제 "Unknown language" 오류가 발생합니다!

실제로, 이는 다음에 전달된 언어 옵션을 변경할 때마다 흔히 발생하는 오류 메시지입니다 `babel`또는 심지어 다음을 제거할 때에도 `babel` 패키지를 프로젝트에서 제거할 때입니다. 다행히도, 없애는 것도 쉽습니다: 그냥 [캐시를 지우고](/latex/ko/knowledge-base/028-clearing-the-cache.md) 다시 컴파일하면 사라집니다.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://overleaf-pro.ayaka.space/latex/ko/questions-and-answers/56-i-changed-the-language-option-to-babel-and-now-i-m-getting-a-unknown-language-error.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.
