getting drush to work on a MAMP setup

Drush shouldn't need an alias if you've put it in /usr/bin - you need to read the installation instructions a bit more carefully!

Try typing this though - DON'T log out afterwards;

source /spencerHD/Users/spencer/.profile

Then try the drush command...

Pobster

what works for me is this (in .bash_profile, not in .profile):

alias drush='/Applications/MAMP/bin/php5/bin/php /usr/bin/drush/drush.php'
export COLUMNS

you have to tell drush to use the MAMP version of php as the system one is different.

I had big problems with a OS_X_10.6 + MAMP_1.9 + drush setup, but I solved the issues so I thought I'd post it here in case anyone else was bumping into similar issues. Though if anyone has ideas why some of these problems were popping up - sharing that info would be much appreciated.

If you are using MAMP and want to use drush, install drush as directed in the README but use the php located in /Applications/MAMP/bin/php5.2/bin

• back up your site files and database
• chage your .bash_profile alias for drush to use MAMP's php:
  

  alias drush='/Applications/MAMP/bin/php5.2/bin/php /path/to/drush/drush.php'
  export COLUMNS
  

• allow MAMP's php to be executable by drush chmod +x /Applications/MAMP/bin/php5.2/bin/php
  otherwise you will receive permission errors such as...

  $ drush
  -bash: /Applications/MAMP/bin/php5.2/bin/php: Permission denied

• you probably will want to increase the max memory allowed for any php script in memory_limit from 32M to 96M or 128M or greater here: /Applications/MAMP/conf/php5.2/php.ini
• restart your MAMP servers
• open a new terminal

Note that you can also use the php located in /Applications/MAMP/bin/php5.3/bin but I got a bunch of warnings/errors with drush when I did that due to various modules I was using that aren't 5.3 compatible (or haven't been upgraded to versions that are 5.3 compatible). Likewise MAMP can be set to use php 5.2 or 5.3 - with similar results regarding warnings/errors that will pop up inside drupal admin pages.

Regarding my experience with using Mac's default PHP...

I recently upgraded to Snow Leopard (10.6) and also upgraded my MAMP to 1.9 (released: 2010-04-16). At each stage I tested my local sites and they were working fine.

Reinstalled drush and the first round of warnings/errors began. I was just using the default Mac provided php and received various warnings...

$ drush dl backup_migrate
PDO::__construct(): [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock)     [warning]
environment.inc:955
SQLSTATE[HY000] [2002] No such file or directory                                                        [warning]
Project backup_migrate (6.x-2.2) downloaded to                                                          [success]
/Users/lclusr/wwwroot/example/sites/all/modules/backup_migrate.

and sometimes errors...

$ drush en backup_migrate
PDO::__construct(): [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) environment.inc:955    [warning]
SQLSTATE[HY000] [2002] No such file or directory                                                                           [warning]
Drush was not able to start (bootstrap) the Drupal database.                                                               [error]
Hint: This error often occurs when Drush is trying to bootstrap a site that has not been installed or does not have a
configured database.

Drush was attempting to connect to : 
  Drupal version    : 6.15
  Site URI          : http://default
  Database driver   : mysqli
  Database hostname : localhost
  Database username : example
  Database name     : example
  Default theme     : garland
  Administration theme: garland
  PHP configuration : 
  Drush version     : All-versions-3.0
  Drush configuration: 
  Drupal root       : /Users/lclusr/wwwroot/example
  Site path         : sites/default
  Modules path      : sites/all/modules
  Themes path       : sites/all/themes
  %paths            : Array

You can select another site with a working database setup by specifying the URI to use with the --uri parameter on the
command line or $options['uri'] in your drushrc.php file.

Command pm-enable needs a higher bootstrap level to run - you will need invoke drush from a more functional Drupal         [error]
environment to run this command.
The drush command 'en backup_migrate' could not be executed.                                                               [error]

Just for the record the site was already installed and had a working configured database.

Also I've installed a mysql server on my mac via fink previously, but I am not using it and it is not running. Still - not sure if some of these Mac default php problems I was experiencing are due to some settings my mysql installation created somewhere or something that's the usual experience for people using 10.6.

After all this I opted to try to use the php supplied in MAMP and after some trial and error arrived at the steps shown in the list above.

php executable is in a new location with this version of MAMP (PRO).

So in your ~/.bash_profile or ~/.bash_exports the correct PATH export for drush to work is:

export PATH="/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php/php5.2.17/bin:$PATH"

or .../php5.3.6/bin as appropriate to your set up.

I have had a lot for problems in the past to get drush to play nice with MAMP.

Here is my guide and it seem to work fine.

Note MAMP should be running

1. Download drush from http://drupal.org/project/drush
2. Move the downloaded file to the desktop
3. Decompress the downloaded file
4. Open terminal
5. Create a new folder for drush
Terminal command: sudo mkdir /usr/local
6. Move the drush to new folder
Terminal command: sudo mv ~/Desktop/drush /usr/local
7. Make drush folder writable so self update will work
Terminal command: sudo chmod 0777 /usr/local/drush/
8. Make drush executable
Terminal command: sudo chmod u+x /usr/local/drush/drush
9. Create symbolic link so MAMP php is the default php
Terminal command:
sudo ln -fs /Applications/MAMP/bin/php/php5.3.6/bin/php /usr/bin/php
10. Create symbolic link so MAMP mysql is default mysql
We need 2
Terminal command:
sudo ln -fs /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
sudo mkdir /var/mysql
sudo ln -fs /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql/mysql.sock
11. Create a .profile file. So you can execute drush from anywhere
Terminal command: sudo nano.profile
Then copy and past the below from start to end
#START
alias drush='/Applications/MAMP/bin/php/php5.3.6/bin/php /usr/local/drush/drush.php'

export PHP_VERSION="5.3.6"

# HOME folders
export MAMP_HOME="/Applications/MAMP"
export PHP_HOME="$MAMP_HOME/bin/php$PHP_VERSION"

# DRUSH
export DRUSH_PHP="$PHP_HOME/bin/php"

# PATH
export PATH="$MAMP_HOME/bin:$PATH"
export PATH="$MAMP_HOME/Library/bin:$PATH"
export PATH="$PHP_HOME/bin:$PATH"
#END

12. Then save the .profile file
Press: Control + x
Press: y
Press: return

13. Quit terminal to reload .profile file

14. Drush should now be working
Terminal command: drush
This should return a bunch drush related commands
Terminal command: mysql
This should give the a mysql prompt

Sorry guys, but you cannot use /usr/bin/ folder for drush. Because this folder for system bins only.
For custom bins we must use folder like /usr/local/bin/

But unfortunately OSX don't use this folder by default =)
For fix it we can add "PATH=$PATH:/usr/local/bin" to ~/.bash_profile

cat "PATH=$PATH:/usr/local/bin" >> ~/.bash_profile
source ~/.bash_profile

But drush is not just bin, it's folder with files.
Because of this we need to copy it to /opt/ folder and create symlink to /usr/local/bin

So, this is more "Linux way":

sudo git clone https://github.com/msonnabaum/drush.git /opt/drush
sudo chown -R www /opt/drush
ln -s /opt/drush/drush /usr/local/bin/drush

Be sure you've also got port 8889 (if you're using MAMP default) specified in your database area of settings.php (hat tip).
