How to move to another branch without a commit?

Question

git

Hello, I have a question about git. After executing the "composer update" command, the "composer.lock" file changes and I cannot switch to another branch until I make a commit. How to make it so that it would not be necessary to make a commit?
Here is the text of the error:
error: Your local changes to the following files would be overwritten by checkout:
composer.lock
Please commit your changes or stash them before you switch branches.
Aborting

Answer 1

why would you do a "composer update"? if you need to install what others have done, then you need to do "composer install"

Answer 2

As far as I understand, this file must be registered in .gitignore and git will not pay attention to it.
