Command 'ui' is not defined in laravel 6.0

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

Shouldn't you deal with the fatal error thrown by your PHP before worrying about laravel UI, lack of memory can create issues for Composer – Staves

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.

when i use second command it still says " ui command is not defined" . why? i'm using laravel 7 – Lemmuela

Note: You will need to specify a version for laravel ui if you are installing an older version of the framework. For Laravel 6 the command is composer require laravel/ui "1.*" and I believe laravel 7 is composer require laravel/ui "2.*" – Wanettawanfried

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

Are you sure that you have installed the mentioned package? – Desensitize

@AbhishekThakur it looks like you have an infinite loop that is using all the memory, check this post to know more about this error and possible solutions. – Desensitize

not worked, i try maximun solution but not worked in there, composer install in system but UI not defind – Viehmann

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

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

Answer 10

I have just started learning laravel and facing the same issue. I have not proper idea about proper way to start learning laravel. So I did the silly mistake.

I have installed composer using

composer create-project laravel/laravel EMS
composer require laravel/ui

Then opened EMS(laravel project's folder) in command prompt. and ran

php artisan ui bootstrap

So, I got error ui not defined, My mistake was I ran composer command out of the project folder, and artisan command in project. So I have ran all above command in project's folder and everything is working fine.

I don't know this is correct way to do this or not, but my issue is solved using this method. So, I thought to share with users, if my way is wrong than anyone can also suggest better way.
