How to install drush for Drupal 7

dstrum

Does anyone have experience installing Drush for Drupal 7 on Opalstack?

Thanks.

sean

Apologies for the late reply!

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

Create a shell user for your app if you've not done so already.
Create a MariaDB database and user and make a note of the DB name and credentials.
SSH to your server as your shell user.
Install Composer by following these instructions: Installing Composer

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

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.

sean

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

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!

featherbelly Thanks, post updated 🙂

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

sean

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

composer require drush/drush:8.4.8

Problem 1
- Root composer.json requires drush/drush 8.4.8 -> satisfiable by drush/drush[8.4.8].
- drush/drush 8.4.8 requires consolidation/annotated-command ².12.0 -> found consolidation/annotated-command[2.12.0, 2.12.1] but the package is fixed to 4.4.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Cheers,

sean

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.

kabal

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

kabal

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'

[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

kabal that error is a bug in the version of Drush that you're using: https://github.com/drush-ops/drush/issues/2065

Some possible workarounds from that page:

modify startup.inc in your drush installation.
unset module in your shell environment.

kabal

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

nick

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
