How to configure the Laravel built-in web server?

Question

I am running this command:

C:\xampp\htdocs\notebook>php artisan serve

However I get this error:

Warning: require(C:\\xampp\\htdocs\\notebook\\bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in C:\\xampp\\htdocs\\notebook\\bootstrap\\autoload.php on line 17

Fatal error: require(): Failed opening required 'C:\\xampp\\htdocs\\notebook\\bootstrap/../vendor/autoload.php' (include_path='.;C:\\xampp\\php\\PEAR') in C:\\xampp\\htdocs\\notebook\\bootstrap\\autoload.php on line 17

Answer 1

创建项目或克隆现有项目后，应运行composer install命令，该命令将安装所有依赖项并创建autoload.php文件。

Answer 2

That is an import error.

Everytime you have one of these, you should try to run composer dump-autoload .

Most of the time, this command will fix your imports.

Answer 3

It looks like you might not have installed the required dependencies yet. You should do so using the composer package manager, like so:

C:\ProgramData\ComposerSetup\bin\composer install
