How to resolve the issue of the main text content not displaying after running LaTeX?

If the body content is not displaying after typesetting with LaTeX, you can try the following solutions:

1. Check for errors in the code: Look for syntax errors, spelling mistakes, symbol errors, etc., as they may cause the main text to not display properly. Carefully examine the code and correct any possible errors.
2. Check the encoding format of the file: The encoding format of LaTeX files should be UTF-8. If the encoding format of the file is incorrect, the main content may not be displayed correctly. Use a text editor to change the encoding format of the file to UTF-8.
3. Check if the LaTeX package is installed: Some LaTeX packages contain commands and environments for typesetting. If these packages are not installed or cannot be found, it may cause the content of the document not to display. Make sure that the necessary LaTeX packages are correctly installed and referenced in the code.
4. Check if the document class is correct: LaTeX provides different document classes for different types of document formatting, make sure the document class you are using is correct to ensure the main text content displays correctly.
5. Clear cache files: During LaTeX compilation, some intermediate files are generated which may sometimes cause issues. Try deleting the intermediate files generated during LaTeX compilation and then rerun the compile command.

If none of the above methods work, you can try asking for help in the LaTeX community or forum to seek more professional assistance.
