Answer 1

You need a working drupal installation, meaning php can be executed the mysql server can be reached. Then you have to change into the root directory of your installation - in your case:

cd /opt/lampp/htdocs/projects/drupal_test/

and execute the command:

drush en modulename -y

For debugging use

drush rq

Answer 2

If you tried changing localhost to 127.0.0.1 in settings and it still doesn't work, please have a look at the solution I found here:

Drush: “Command pm-enable needs a higher bootstrap level to run

When running drush you can run into this error message. In my case, the mysql command line tool provided with Mamp Pro was not available. You can easily test this by typing the command ‘mysql’ in terminal. Your output might be -bash: mysql: command not found.

To solve this, do the following in terminal:

sudo vim ~/.bash_profile

Press i Move to the last line and append

export PATH=/Applications/MAMP/Library/bin/:$PATH

Hit escape Type in :wq (including the colon) to write the file and quit vim. Reload your profile by running source ~/.bash_profile.

The mysql command AND drush should now work!
