I installed drush 9 and now I'm getting the following error whenever I run a drush command:

/usr/bin/sh: /cygdrive/c/mysite/vendor/drush/drush/drush.launcher: No such file or directory


  • I have installed drush 9 on Windows 7 using composer. This was an update to my previous drush 8.

  • The drush files are installed in my local site's vendor directory.

  • The drush.launcher file is in the directory indicated in the above error message.

  • To run a drush command, I go to my site's root directory using MINGW64 and run the command using vendor/bin/drush. for example:

vendor/bin/drush drusn --version
  • I have C:\mysite\vendor\bin in my path environment variable.

  • I don't want to use drush.launcher at this time but not sure why it gets invoked and yet not found.

Thank you in advance for your help.

  • I have posted an initial answer below. In general it's easier to help if you provide as much info as possible - the exact version of Drush and Drupal, the environment you are running it in (Cygwin on Windows I assume) and so on.

  • Thanks @hansfn. This is part of my effort to update my Drupal 8.1.x to 8.6.15 which requires drush 9. Should I have updated Drupal before installing drush 9?

  • No, but you are aware that you should use Composer to update Drupal 8, not Drush? Anyway, if you had indeed correctly upgraded to Drush 9 there should be no drush.launcher.

  • @hansfn sorry for the confusion. I am using Composer to update Drupal 8. Drush is listed in my composer.json as a dependency with ^9.0.0 but I've had no luck getting it to work.

  • To repeat myself (as in my answer below). There should be no vendor/drush/drush/drush.launcher. What version does composer info drush/drush return?

Drush 9 doesn't come with drush.launcher so something is wrong with your Drush installation / update. You should try to fix that by updating or reinstalling Drush. However, in the meantime just delete drush.launcher.

PS! It's recommended to install Drush Launcher in addition to the site-local Drush.

  • thanks for your hint about drush.launcher and that my drush installation is not correct. I still have issues with updating my drush but I'll mark this as an answer since I'm now dealing with a different type of issue.
