Laravel 5 Failed opening required bootstrap/../ven

Question

I have recently installed Laravel 5 via composer. I tried creating a new controller using artisan and I get the following error:

bootstrap/../vendor/autoload.php. Failed to open stream: No such file or directory. The "vendor" folder does not exist.

Am I missing something?

Answer 1

Did you create a new project or did you clone an existing project?

If you cloned an existing project it's very important to run

composer install

That way all the dependencies that are missing will be installed.

But if you create a new project you should run this command to make a new project using composer

composer create-project laravel/laravel name-of-your-project

Answer 2

Just run this inside the directory where you installed your project

composer install

Answer 3

In my case I had to enable another extension, namely php_mbstring.dll in the php.ini file before it could work. It's listed under extension=php_mbstring.dll. Find it in the php.ini file and remove the semi-colon (;) in front of it and save the file.

After this run install composer again in the root directory of your Laravel applcication and is should work.

Answer 4

Just run the following commands,

composer update

Or

composer install

Answer 5

I had same problem with laravel and artisan, the solution:

php artisan key:generate
