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

`
[kabal@opal4 rescueminute]$ composer require drush/drush:8.4.8
./composer.json has been updated
Running composer update drush/drush
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

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.

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

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).

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

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!
