Error reported when files are generated by template compilation in smarty

The error code of the files generated by the smarty template compilation is good on my friend's computer. When it is opened on my computer, an error will be reported at template_c. Check that the Code pointing to the error does not find any problem.
How is temlpate_c generated? Can I delete it? Is it related to configuration? Later, I used another person's full set of code, and there were more files with errors reported in template_c, but there was nothing wrong with the original computer. Depressed.

How can I generate a new one after deletion?
I haven't moved any other places. After I deleted template_c, I reported an error when I opened almost every page on the webpage. After I restored it, I got it again.

After the file is deleted and regenerated, the tpl folder under the templates folder is almost full of red ...... Is there a problem with the code of my template file?
