A trap of Drupal Installation

Drupal is easy to install. decompress the Drupal source code package to your web path, enter this address, and then follow the prompts to do it step by step. However, if you do not strictly follow the requirements of Drupal, there will be some inexplicable errors.
In the first step of installation, Drupal prompts you

./Sites/default/Default. settings. php

Copy this file into a file named

./Sites/default/settings. php

.
At this time, many people directly change the file name of default. settings. php to settings. php to save effort. In this case, the following warning message is displayed during installation:

Warning: fopen (. /sites/default. settings. PHP) [function. fopen]: failed to open stream: no such file or directory in c: \ XAMPP \ htdocs \ Drupal \ mongodes \ install. INC on line 188

Warning: cannot modify header information-headers already sent by (output started at c: \ XAMPP \ htdocs \ Drupal \ mongodes \ install. INC: 188) in c: \ XAMPP \ htdocs \ Drupal \ shortdes \ install. INC on line 618
