require(vendor/autoload.php): failed to open stream

Question

I know that this issue has been posted many times, but for me it seems to be a different problem.

Indeed, this error

Warning: require(vendor/autol

Answer 1

If you have cloned your project from Github or got it from somewhere else, you will encounter this error. That's because you are missing the vendor folder and other files. The vendor folder contains packages which are dependent to your project. The package dependencies are stored in composer.json file and the folder was excluded while pushing to Github.

Fix this error by simply running:

composer install

Then you will get all the assets needed for your project.
