How to enable error prompts in TP5?

How to enable error prompts in TP5:

When using the tp5 framework, the error message will not be displayed during testing, only "The page has an error" will be displayed. , I have checked many methods, and now I will summarize:

tp5 does not display error messages in deployment mode. To enable debugging mode,

set define in public/index.php, which is the entry file. ('APP_DEBUG', true);

Set in config.php

'SHOW_PAGE_TRACE'=>true,
'debug' =>true,

After turning on the debugging mode, I found that the error was still not displayed. I checked convention.php (under the file entry thinkphp) and found that there is an item in the exception and error settings
'show_error_msg' => false, change it to true, and then the error message will be displayed.

Supplement:

I found that tp5 has two files, config.php and database.php, in the application directory. You can modify them directly in these two files, so there is no need. Create a new conf/config.php to modify it. If this file is created, the original settings of config.php and database.php in the application directory will be invalid.
