sudo apt-get install libgl1-mesa-glx
|
|
```

??? question "Missing text information in parsing results when installing and using on Linux systems."
|
|
|
|
MinerU uses `pypdfium2` instead of `pymupdf` as the PDF page rendering engine in versions >=2.0 to resolve AGPLv3 license issues. On some Linux distributions, due to missing CJK fonts, some text may be lost during the process of rendering PDFs to images.
|
|
To solve this problem, you can install the noto font package with the following commands, which are effective on Ubuntu/Debian systems:
|
|
```bash
|
|
sudo apt update
|
|
sudo apt install fonts-noto-core
|
|
sudo apt install fonts-noto-cjk
|
|
fc-cache -fv
|
|
```
|
|
You can also directly use our [Docker deployment](../quick_start/docker_deployment.md) method to build the image, which includes the above font packages by default.
