Drupal-console: [ERROR] Drupal Console is not installed at: /myD8Folder

[KlemensHeinen]

Outside any Drupal-Folder the console works fine.
Inside it throws this:
_[ERROR] Drupal Console is not installed at: /data/www/x8/
You must execute this composer command:
composer require drupal/console:~1.0 --prefer-dist --optimize-autoloader_
This happens with a freshly downloaded (uninstalled) D8.
Besides: After executing the cmd, it works, but I dont want to have additional 8MB in my installation...

My System: Mamp, Drupal Console Launcher (1.0.0-rc2)

I'm also encountering this.

Same problem

I get same error. It was working fine until I did a drupal self-update. Now I get this message

./composer.json has been updated

I tried to re-install using composer but I get same error.

composer global remove drupal/console
composer clearcache
composer global require drupal/console:@stable

@KlemensHeinen , @jdleonard , @tensor146 and @robertloo you will find an asnwer to this issue at this comment I did on a similar reported issue:

[whikloj]

@jmolivas I have experienced the above error when installing drupal-console globally via the PHAR, then installing drupal 8 using drush. Then trying to use drupal-console in that drupal 8 install.

Is this not possible, or is there something I need to do?

EDIT

To clarify I mean is:

1. Do I need to install drupal-console using composer (which seems to be the solution in the linked ticket) or can I still use the PHAR?
2. Can I install drupal with drush and still use drupal-console, or do the two applications conflict in some way.

[jmolivas]

@whikloj:

1.- The phar is only a launcher tool to find and execute DrupalConsole.

2.- You can install both.

But even when installing the global phar you still need to install DrupalConsole per site.

[BrizzleRocker]

But even when installing the global phar you still need to install DrupalConsole per site.

This is very unclear in the install instructions and throughout the documentation. I suspect that many people (like me) will assume this utility is similar to drush or composer in that you install once and use everywhere.

[jmolivas]

@BrizzleRocker Yes totally agree we need to make docs more clear. Any suggestions are more than welcome.

[siolfyr]

What was the benefit that made you decide to require Drupal Console to be installed on a per-site basis? This is going to cause more difficulties for people when installing, especially if they have conflicting packages.

[queenielow]

Hi Guys,

I have this error message too.. Was wondering has this resolve? or any solutions?

Thanks,
Queenie

[jmolivas]

@queenielow what is the error you are getting?

[queenielow]

Hi Jmolivas,

My error are the same as robertloo.

Thanks

[jmolivas]

@queenielow can you try download DrupalConsole by executing

composer require drupal/console:~1.0 \
--prefer-dist \
--optimize-autoloader \
--sort-packages \
--no-update

By using the --no-update flag we are disabling the automatic update of the dependencies.

Finally just execute the following composer command to update project dependencies.

composer update

[queenielow]

Thanks alot @jmolivas .. It work!

[tomasHegi]

@jmolivas your solution is not working for me in Drupal VM. After I installed drupal/console via composer I get following error:
PHP Fatal error: Cannot use Drupal\Console\Core\Bootstrap\DrupalConsoleCore as DrupalConsoleCore because the name is already in use in /vendor/drupal/console/src/Bootstrap/Drupal.php on line 11

Anyway, I still didn't get it, why it's needed to install console on per-site basis.

[jmolivas]

@tomasHegi

Anyway, I still didn't get it, why it's needed to install console on per-site basis.

This was done to try to minimize dependency conflicts and support multiple releases of Drupal.

Not sure what your error I am currently using DrupalVM in some project without any issues.

[jmolivas]

@tomasHegi try instead running drupal from your site root directory vendor/bin/drupal

[kentr]

The line in @tomasHegi error report is just a use statement.

use Drupal\Console\Core\Bootstrap\DrupalConsoleCore;

I wonder if it's due to this PHP bug

Original mention here: http://stackoverflow.com/questions/17746481/cannot-use-x-as-y-because-the-name-is-already-in-use-even-though-its-not

[jmolivas]

@tomasHegi how did you installed the Launcher aka global executable?

[tomasHegi]

@jmolivas thanks, using vendor/bin/drupal console works

[jmolivas]

@tomasHegi try reinstalling the global executable https://github.com/hechoendrupal/drupal-console#install-drupal-console-launcher

[hatuhay]

@jmolivas openned this issue https://github.com/hechoendrupal/drupal-console/issues/3181 regarding @tomasHegi issue...

This suggestion does not work.
Screenshot attach.

EDIT:
Having said that; It is clear that drupal console is now (practically) not globally available. We are forced to install on every drupal project drupal console, if we want access to drupal console.

[alisyed-drupalmaze]

Step 1.

composer require drupal/console:~1.0 \
--prefer-dist \
--optimize-autoloader \
--sort-packages \
--no-update

Step 2.
composer update

Note:- Make sure run above command where composer.json located.
