How to install Yii2 engine on hosting?

Question

CMS

Good day!
For a very long time I was looking for an engine with a form for searching for air tickets, and finally I found it on github! But there is a problem with the installation. How to install Yii2?
Here is the ENGINE ITSELF , there is also an installation instruction. But I did not understand almost nothing of what is written there. I uploaded all the files to the hosting, follow the link to my site, and there it says the following:
"It seems that you forgot to install the necessary dependencies. Please read the instructions for further work."
Like, something is missing. How to be?

Answer 1

You need to execute the command in the console
. To do this, you need to put the composer itself.
All this is in the README of your engine.
And now the problem is, if you have access to hosting via ssh, then in principle there is a possibility that you can install the composer on the hosting server and perform all manipulations there. If the hosting does not allow this, then you will have to deploy the site on your home machine (install PHP, web server, etc.), install the composer through it, download all the dependencies and then transfer the entire project directory to the hosting.
