How to install bower components from bash.sh file?

Question

JavaScript

There is a bash file and a configured bower.
If you execute bower install from the folder with bower.json, then everything is installed normally. But if I am at the root of the server, then this command can no longer be installed.
I have a bash file from which I want to run the installation of all bower components. But it is located in a different location, which means that the bower install command does not work for it. How to correctly write a command in the console to install bowek components?
Tried:

/var/www/sait.ru/bower install
/var/www/sait.ru bower install
bower /var/www/sait.ru install
bower install /var/www/sait.ru
bower install --working-dir=/var/www/sait.ru

Answer 1

For example like this:
cd /var/www/sait.ru/; bower install
