[BUG] 系统正常启动后，“添加文件到知识库文档“，“重新添加至向量库”点击后后台报错，前台文档加载器，分词器为空，文档数量为0，源文件向量库文件是叉叉 about langchain-chatchat HOT 4 CLOSED

To address the issues you're experiencing with adding files to the knowledge base and encountering backend errors, consider the following steps:

1. Check for File Type and Encoding Issues: Ensure the CSV file you're uploading matches the expected format and encoding. Issues often arise from mismatches in these areas. If you're working with .doc files, ensure they're correctly recognized by adjusting the file type settings if necessary.

2. Synchronize Frontend and Backend: If the frontend displays incorrect information, such as an empty document loader or tokenizer and a document count of 0, ensure that the frontend is correctly querying the backend for updates. This might involve verifying the synchronization process between the two.

3. Verify File Registration in the Database: For the issue with the crossed-out source file in the vector library, check if the document exists in the database and is correctly registered. Utilize database functions to check the file's presence and refresh its state if inconsistencies are found.

4. CSV File Requirements: When uploading CSV files, ensure they adhere to the supported format and encoding. The system is designed to automatically detect and handle various encodings for CSV files, which can help avoid issues during the upload process.

If these steps do not resolve your issues, please provide more detailed error messages or logs to help diagnose the problem more accurately.

Thank you. It was indeed due to the file format problem in the csv, and the error was solved after I reformatted it

谢谢。确实是由于csv中的文件格式问题，重新格式化后错误就解决了

我上传doc格式也是报这个错误，应该如何解决呀

要解决这个问题，需要在 WSL 中安装缺失的库。由于 WSL 基于 Linux，所以可以使用 Linux 的包管理器来安装这些库。如果你的 WSL 分发版是基于 Debian 或 Ubuntu 的，
可以使用以下命令安装：
sudo apt-get update
sudo apt-get install libgl1-mesa-glx
