Laravel 5 Failed opening required bootstrap/../vendor/autoload.php

PhpLaravel 5

Php Problem Overview

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?

Php Solutions

Solution 1 - Php

Run composer with --no-scripts

composer update --no-scripts

This shall fix the issue. I tried this on Mac and Linux.

Solution 2 - Php

Which OS you are using ? For Windows : Go to Command Prompt

set path to www/{ur project}

For me : www/laravel5

Then type this command : composer install

It will automatically install all dependency in vendor/

Solution 3 - Php

Run composer install in your root project folder (or php composer.phar install).

Solution 4 - Php

Turns out I didn't enable openssl in my php.ini so when I created my new project with composer it was installed from source. I changed that and ran

composer update

now the vendor folder was created.

Solution 5 - Php

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

Solution 6 - Php

I encountered the same problem. It occurred because composer was not able to install the dependencies specified in composer.json file. try running

composer install

If this does not solve the problem, make sure the following php modules are installed php-mbstring php-dom

To install this extensions run the following in terminal

sudo apt-get install php-mbstring php-dom

once the installation is complete

try running the command in your project root folder

composer install

Solution 7 - Php

You need to regenerate autoload.php file. you can use dump-autoload to do that without having to go through an install or update.

use

composer dump-autoload

to generate autoload.php file again in /vendor directory.

Solution 8 - Php

Following this below step solved my problem. You may try

composer update --no-scripts 
composer update

Solution 9 - Php

Just run this inside the directory where you installed your project

composer install

Solution 10 - Php

After checking php version and a lot of research , the problem was on Composer side so just run the following command

composer install --ignore-platform-reqs

Solution 11 - Php

This solution worked for me. The reason is not to have a vendor folder in your application.

Follow these steps:

  1. if your project has composer.json file, delete it

  2. then run

     composer require phpspec/phpspec

That command add vendor folder to your project

Solution 12 - Php

go to your project folder via cmd. run the following command

composer update

it will install the missing vendor folder and files in your project.

but in some cases, it gives an error like "Your configuration does not allow connection to ....." in cmd.

for that go to your composer.json file,

change "secure-http": true to "secure-http": false

but in some cases (as was in my case) you may not find such line in your file. for that do the following action:

change "config": {
        "preferred-install": "dist"
}

to

"config": {
    "preferred-install": "dist",
    "secure-http": false
}

and run again composer update command.

hope this will solve problem.

Solution 13 - Php

Just run the following commands,

composer update

Or

composer install

Solution 14 - Php

When the new project created the laravel require to load vendors to autoload the libraries , We use composer update to

composer update

Composer is a dependency manager allows you to delegate responsibility for managing your dependencies to a third party.

Solution 15 - Php

Just setup a new project using composer instead of laravel like this:

composer create-project --prefer-dist laravel/laravel myProje

Solution 16 - Php

Delete Vendor then composer install

Solution 17 - Php

I also had that error. But none of the above solved the issue. So i uninstalled and again installed the composer. Then i did composer update. and the problem was fixed.

Solution 18 - Php

You are missing vendor folder, probably its new cloned repository or new project

the vendor folder is populated by composer binary which reads composer.json file or system requirements and installs packaged under vendor folder and create an autoload script that has all classed

composer update

Solution 19 - Php

Before you carry out the following instructions you need to make sure you have composer installed globally on your machine; Open you Mac terminal and run the following command:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

once composer is installed globally run the following command after you are in the directory of the project:

composer install

once completed in it update and install all the required packages.

Solution 20 - Php

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

php artisan key:generate

Solution 21 - Php

We got an error because we have missing vendor folder in our project, The vendor directory contains our Composer dependencies.

Need /vendor folder because all packages are there and including all the classes Laravel uses, A problem can be solved after following just two steps:

composer update --no-scripts 
composer update
  • --no-scripts: Skips execution of scripts defined in composer.json
  • composer update: This will check for newer versions of the libraries you required in your project. If a newer version is found and it's compatible with the version constraint defined in the composer.json file, it will replace the previous version installed. The composer.lock file will be updated to reflect these changes.

These two commands, we will Recreate the vendor folder in our project and after that our project will be working smoothly.

Solution 22 - Php

I got this when I did composer update instead of composer install.

Solution 23 - Php

I added composer.lock file to .gitignore, after commit that file to repository error is gone :)

Solution 24 - Php

my problem is solved by

composer update
composer install
php artisan key:generate

if you any other problem you can clear cache and config Clear Route cache:

php artisan route:cache

Clear View cache:

php artisan view:clear

Clear Config cache:

php artisan config:cache

Solution 25 - Php

Something I realise is your composer.json file will have some sort of script like

"scripts": {
    "post-root-package-install": [
        "php -r \"copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
        "php artisan key:generate"
    ],
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "pre-update-cmd": [
        "php artisan clear-compiled"
    ],
    "post-update-cmd": [
        "php artisan optimize"
    ],
    "post-autoload-dump": [
        "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
        "@php artisan package:discover"
    ]
},

what works for me:

"scripts": {
    "post-root-package-install": [
        "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
        "@php artisan key:generate"
    ],
    "post-autoload-dump": [
        "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
        "@php artisan package:discover"
    ]
},

removing post install cmd helped running composer install without any issue.

Hope this helps

Cheers!!

Solution 26 - Php

Delete vendor folder and run composer install command. It is working 100%

Solution 27 - Php

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.

Solution 28 - Php

If you are a Windows user you may uninstall Composer. Then install Composer. After that you install Laravel. Maybe it will work.

Solution 29 - Php

this works for me: after installing the project, I open the project's folder and run these two commands

composer update

composer require doctrine/dbal
