Windows更新1903后，Composer无法使用laravel

Question

Yesterday I updated my windows from version 1803 to 1903. Today I tried to continue work on my laravel application and tried to run PHP artisan serve for development.

What I got was an error message:

PHP Warning: require(C:\\Users\\MY_USERNAME\\MY_PROJECT/vendor/autoload.php): failed to open stream: No such file or directory in artisan on line 18

Warning: require(C:\\Users\\MY_USERNAME\\MY_PROJECT/vendor/autoload.php): failed to open stream: No such file or directory in artisan on line 18 PHP Fatal error: require(): Failed opening required 'C:\\Users\\MY_USERNAME\\MY_PROJECT/vendor/autoload.php' (include_path='C:\\xampp\\php\\PEAR') in artisan on line 18

Fatal error: require(): Failed opening required 'C:\\Users\\MY_USERNAME\\MY_PROJECT/vendor/autoload.php' (include_path='C:\\xampp\\php\\PEAR') in artisan on line 18

But those files exist. I did not change anything after updating to windows 1903.

Answer 1

Its because you haven't installed Composer dependencies so

Cd To your project and run composer install in your terminal
