在 Laravel 5 中打开 autoload.php 失败

Question

I have recently installed Laravel via Composer but I keep get the following error:

Warning: require(/home/leovoon/public_html/laravel-eee/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /home/leovoon/public_html/laravel-eee/bootstrap/autoload.php on line 17

Fatal error: require(): Failed opening required '/home/leovoon/public_html/laravel-eee/bootstrap/../vendor/autoload.php' (include_path='.:/opt/cpanel/ea-php71/root/usr/share/pear') in /home/leovoon/public_html/laravel-eee/bootstrap/autoload.php on line 17

Am I missing something? Because I followed it step by step.

Answer 1

You got an error because you have missing vendor folder in your project, You need /vendor because all your packages are there, including all the classes Laravel uses. The vendor directory contains your Composer dependencies.

Your problem can be resolved after following this step. you can try it:

composer update --no-scripts 
composer update

With this command, you will re-create the vendor folder in your project and after that your project will start working normally.

Answer 2

While Going Live This is my Project Structure

NOTE:WHILE DOING THIS YOU MAY ENCOUNTER SOME STYLE AND JAVASCRIPT REFERENCE ERROR IF YOU ARE USNIG ASSET FUNCTION NO NEED TO WORRY

<link href="{{ asset('css/app.css') }}" rel="stylesheet">

BUT IF NOT IF WILL OCCUR 404 IN SOME CASES

this is Just For Example

Step 1 : create a folder named as `ProjectFiles` in root of your application

Step 2: copy all the contents except and folder except `public` folder and paste inside `ProjectFiles` folder

Step3: now cut and paste all the contents inside the public folder in root of your application root

step4: open your index.php file and make the following changes

require __DIR__.'/../vendor/autoload.php';

to

require __DIR__.'/ProjectFiles/vendor/autoload.php';

AND

$app = require_once __DIR__.'/../bootstrap/app.php';

to

$app = require_once __DIR__.'/ProjectFiles/bootstrap/app.php';

and then upload your project to live cpanel server

here is my cpanel server directory structure

hope it helps if the answer is not clear please comment below if the error continues

Answer 3

Run composer with --no-scripts

composer update --no-scripts  

This shall fix the issue.

Answer 4

Run the command to install all the Laravel dependencies.

php artisan composer:install

If the error still persists, run the command to include all the classes it requires.

composer dump-autoload

Answer 5

You must provide Read and write permissions to your project and generate a key in your .env file

Run the following commands inside your project dir and you would be good to go :

$ sudo chmod -R 777 /storage /public /bootstrap

$ composer install

$ php artisan key:generate

Answer 6

I got this error after trying to start the dev server using php artisan serve This is how I resolved it:

1. Run composer install

In case you get an error like "Your requirements could not be resolved to an installable set of packages", make sure you have the necessary extensions enabled in your php.ini config. In my case I needed to enable extension=fileinfo

1. Run composer update . After this you should be able to start the server with no errors.
