Command 'ui' is not defined in laravel 6.0 - laravel

Question

I start a new project in laravel but my composer installed a fresh version of laravel 6.0.1.
Php artisan make:auth command can't work.
I try many times but error can't remove
composer require laravel/ui
installed but
when I use the second command:
php artisan ui vue --auth
then system show me this message:
Command "ui" is not defined.
Using version ^1.0 for laravel/ui
./composer.json has been updated
Loading composer repositories with package information

Answer 1

you can try this:
C:\Whatever\Your_project_name>composer require laravel/ui
and
C:\Whatever\Your_project_name>php artisan ui vue --auth
Just this two inside your project folder.I am using vue but you can try other ones too.

Answer 2

Did you install the dependency? To run that command you need to install an additional package:
composer require laravel/ui
After this you should be able to run one of these commands:
php artisan ui bootstrap
php artisan ui vue
php artisan ui react
In case you need the auth views, you could:
php artisan ui bootstrap --auth
php artisan ui vue --auth
php artisan ui react --auth
Don't forget to run this after:
npm install

Answer 3

The same error hits me in the new version of Laravel 7.x, What I did the process is really simple: if your composer is old version and the terminal or cmd is giving you warnings to update it using some package then there are chances that the above error hits you.
Solution:
Step 1 : Try the following two commands in your normal terminal not of your project directory. The below command will only update the composer.
composer self-update
OR use the below command (it will update your dependencies plus your composer)
composer update
When you composer gets updated. check the composer by the below command
composer --version
Step 2 : First go to your project root folder C:\Whatever\Your_project_name>
composer require laravel/ui
Try any of the below command according to your front end framework.
php artisan ui vue --auth
php artisan ui bootstrap --auth
php artisan ui react --auth
At the end don't forget to run
npm install
If your User Interface is not working properly try below command.
npm run production

Answer 4

run "composer require laravel/ui 1" instead of "composer require laravel/ui"
laravel 6 works with version 1.0, it written in docs "Want to get started fast? Install the laravel/ui (1.0)"

Answer 5

I was facing the same issue is laravel 8.0, whenever i tried to run this command
php artisan ui vue -auth
after installing the laravel/ui package I was getting the error
command UI is not defined
I fixed this issue by using this command
composer update
it automatically install the laravel/ui package into my project and then I run this command to install the required auth for my web app.
`php artisan ui vue -auth`

Answer 6

You need to create another new project.
You can try this:
composer config -g repo.packagist composer https://packagist.phpcomposer.com
composer create-project --prefer-dist laravel/laravel project2 "7.0.*"
composer require laravel/ui
php artisan ui vue --auth

Answer 7

Just add the version in command line as well:
composer require laravel/ui "^1.0" --dev
Check this too.

Answer 8

using
composer require laravel/ui:*
worked for me

Answer 9

I recently faced this issue after upgrading from laravel 6 to 8. Installing laravel/ui did not work for me because the package was already installed.
I solved it by manually deleting cache folder at bootstrap/cache
