Sometimes we have submitted the file before adding the .gitignore file. .gitignore can only ignore files that have not been tracked (files that have never been added or committed since they were added). If some files have been included in version management, modifying .gitignore is invalid. Just need to execute:

git rm -r --cached . #删除追踪状态
git add . 
git commit -m "fixed untracked files"

/config/config.phpIt is not the file in the config directory in the current directory, but the config directory in the root directory

changed to

git rm --cached ./config/config.php

The dot represents the current directory

Of course, it’s okay if you don’t add ./, the default is the current directory

Follow the above method and it will prompt that the file cannot be found in the index
