'drush' is appended to each path breaking its commands

Question

I don't normally use Drush on Windows, but tried it and noticed that it appends drush as a kind of root directory for any action, thus breaking said action.

For example, drush dd gives:

The command could not be executed successfully (returned: 'Path/To/Composer/vendor/drush/drush/drush' is not recognized as an internal or external command, operable program or batch file. , code: 1)

The correct path is Path/To/Composer/vendor/drush/drush.

When running drush en mymodule, the debug information contains the following.

[preflight] Alias paths: drupal\site\root/drush/sites,drupal/site/root/drush/sites

drupal/site/root/sites I think makes more sense.

The error is Command pm:enable was not found.

Maybe this is a coincidence and the two are unrelated, but how does one configure Drush directories?

The Drush version is 9.5.2.

Answer 1

I haven't used Drush under Windows, but something tells me that the problem could be solved by by editing the path to the Drush executable, perhaps in a Windows environment variable.

Answer 2

I don't think you have installed Drush 9 correctly as Drush is trying to execute

Path/To/Composer/vendor/drush/drush/drush 

Drush 9 should be installed site-locally, not globally, and be launched using Drush Launcher - see http://docs.drush.org/en/master/install/

We can't help you anymore without knowing how you installed Drupal and Drush. The recommended approach to install Drupal is using https://github.com/drupal-composer/drupal-project (which includes a site-local Drush).

PS! vendor/drush/drush/drush exists, but it is a script for Linux.
