Apologies for the late reply!

I've got instructions to install the latest Drush & Drupal. Maybe they can be adapted to your case:

  1. Create a shell user for your app if you've not done so already.
  2. Create a MariaDB database and user and make a note of the DB name and credentials.
  3. SSH to your server as your shell user.
  4. Install Composer by following these instructions: Installing Composer
  5. Install Drupal and Drush, providing your database credentials when prompted: 
        cd ~
    composer create-project drupal/recommended-project mysite 
    cd mysite
    composer require drush/drush
    ./vendor/bin/drush site:install
  6. Create a symlink app using /home/shelluser/mysite/web/ as the symlink path and attach that app to your site.

(I used mysite as the Drupal install directory but you can change that to whatever you need it to be.)

    Hello.
    I have the next issue:

    Running composer update drush/drush --with-all-dependencies
    Loading composer repositories with package information
    Updating dependencies
    Your requirements could not be resolved to an installable set of packages.

    Problem 1
    - composer/installers is locked to version v1.5.0 and an update of this package was not requested.
    - composer/installers v1.5.0 requires composer-plugin-api 1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.
    Problem 2
    - wikimedia/composer-merge-plugin is locked to version v1.4.1 and an update of this package was not requested.
    - wikimedia/composer-merge-plugin v1.4.1 requires composer-plugin-api 1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.

    You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

          josueValrob I think you've got some kind of version mismatch between some combination of PHP, Drupal, drush and/or composer.

              How would I install drush for an existing installation of Drupal 7 (like one that was ported over from webfaction).

              I have been singularly unsuccessful at installing the correct version of drush (one that is compatible with Drupal 7 (like 8.4.8).

              I've mucked something up, but I'm not sure exactly how. The version of drush that runs outside of the app directory is 8.4.8 and seems a little broken. The version of drush that runs inside my app directory is 10.6.1 (not compatible with Drupal 7.

              How do I fix this?

              I want to run drush 8.4.8 everywhere (it's compatible with most versions of Drupal I use).

              The installation instructions here are quite opaque.

              Thanks in advance,
              Dave

                kabal to install Drush 8.4.8, go into whichever app directory and run:

                composer require drush/drush:8.4.8

                    sean

                    `

Make sure you list it as an argument for the update command.

                    • sean replied to this.

                        kabal you could try a standalone installation like so:

                        mkdir ~/drush
cd ~/drush
composer require drush/drush:8.4.8
export PATH=$HOME/drush/vendor/bin:$PATH

                        This will give you a single drush installed in ~/drush that you can use with whatever Drupal 7 sites you have.

                            sean Installation above worked perfectly. Refuses to use the correct version.

                            [kabal@opal4 rescueminute]$ which drush
                            ~/drush/vendor/bin/drush
                            [kabal@opal4 rescueminute]$ drush status
                            PHP binary : /usr/bin/php
                            PHP config : /etc/php.ini
                            PHP OS : Linux
                            Drush script : /home/kabal/apps/rescueminute/vendor/drush/drush/drush
                            Drush version : 10.6.1
                            Drush temp : /tmp
                            Drush configs : /home/kabal/apps/rescueminute/vendor/drush/drush/drush.y
                            ml

                              OK SOMETHING is working. I deleted the vendor/drush directory.

                              Every drush command produces the following error, but seems to succeed:

                              [kabal@opal4 rescueminute]$ drush up
                              sh: module: line 1: syntax error: unexpected end of file
                              sh: error importing function definition for 'BASH_FUNC_module'

                              OR

                              [kabal@opal4 rescueminute]$ drush status
                              sh: module: line 1: syntax error: unexpected end of file
                              sh: error importing function definition for 'BASH_FUNC_module'

                              So.... progress.

                                sean Awesome, the second one worked (first one not so much).

                                  a year later

                                  kabal It looks like composer is either not installed or not included in your PATH. You might need to restart your SSH terminal session after installing composer, or just use the path in the command when running it, eg.
                                  ~/bin/composer require drush/drush:8.4.8

                                    a year later

                                    sean after reading this, I downgraded Drush from 10 to 9 on my Drupal 8 site with PHP 7.3, it worked perfectly. Thank you!
