composer install

If the dependency problem still cannot be solved, you need to re-create a new laravel project , and then import the code and configuration files into the new project.

4. PHP version issue

Laravel has requirements for PHP version. If your PHP version does not meet the requirements, an error will occur. Before running, make sure your PHP version matches laravel's requirements.

You can check your PHP version through the following command:

php -v

If your PHP version does not meet the requirements, then you need to upgrade your PHP version or adjust the laravel version to suit you PHP version version.

5. Other issues

The above lists common causes and solutions for laravel running errors, but in fact, there are many other reasons for laravel running errors. If you encounter an error that cannot be solved, you can try the following solutions:

  1. Ask for help from community members or developers;
  2. Find solutions through search engines;
