pm install?

Use --verbose for a start :-)

you have cvs command in your PATH? if not, disable the cvs handler and use the wget handler instead. hopefully you have wget or curl. if not, you have to get one of those.

You probably have drush cvs package manager installed. Goto admin/build/modules and check the enabled drush modules.

Enable 'drush Package Manager wget Support' and disable 'drush Package Manager CVS Support'

I had the same error concerning CVS: well, I decided to install CVS - and magically it works now :-D
Did you verify that CVS is installed?

mpaler I have this exact issue and it is driving me NUTS. have you found a solution????

Changing version to 6.x because it is not a version-specific issue.
Changing priority to critical because this has yet to be resolved for several months and it is preventing many users from using this kickass module.
Category stays as "support request" because this is a server config problem, not a bug.

> I'm the root admin on my VPS which is running Centos 5.

When I installed drush, I put it in: /var/www/vhosts/mydomain.com/httpdocs/sites/all/modules
(( the result is /var/www/vhosts/mydomain.com/httpdocs/sites/all/modules/drush ))

Then I turned on all the modules on the modules config page.

Now, option 3 in the README under "Installation" states:

3. (optional, but recommended:) To ease the use of drush,
- create a link to drush.php in a directory that is in your $PATH, e.g.:
$ ln /path/to/drush.php /usr/bin/drush
OR
- create an alias to drush.php:
$ alias drush='php modules/drush/drush.php'
(this goes into .profile or .bash_aliases in your home folder)

So I logged in as root in the drupal base directory
(( /var/www/vhosts/mydomain.com/httpdocs/ ))

And executed this command: $ ln sites/all/modules/drush/drush.php /usr/bin/drush

Then I loggged out of root. (I'm still in the drupal base directory)

I am able to execute every drush command successfully, except for "drush pm install ...". (This is the exact problem as #7).

-sh-3.2$ drush pm install simplemenu
PHP Notice:  Undefined index:  host in /usr/bin/drush on line 98
sh: /wget: No such file or directory
sh: /curl: No such file or directory
E: Unable to download simplemenu-6.x-1.x-dev.tar.gz to /var/www/vhosts/mydomain.com/httpdocs/sites/all/modules/ from http://ftp.drupal.org/files/projects/simplemenu-6.x-1.x-dev.tar.gz

The same issue happens when using the CVS method. (/cvs: No such file or directory).

So.... What is causing this?? I've been giving it my best shot for 3 days non-stop and I can't figure it out. I don't think it's the PHP Notice, based on other issues... (other people are still able to install modules even though they get similar PHP Notices)...

And yes, I am able to use wget by executing the following command: "$ wget http://ftp.drupal.org/files/projects/[drupal module]"
But drush is having trouble using wget... Hmmm.......

Please help me resolve this issue! I will try any and all suggestions. I fear this may scare a lot of people away from using drush, but I'm dedicated to finding the solution because a drupal command saves hours!!

THANKS!

I've made some progress....

these commands (as root) fixed my "sh: /wget: No such file or directory" and "sh: /curl: No such file or directory" errors:

ln /usr/bin/wget /wget
ln /usr/bin/curl /curl

then I was presented with similar errors, but for "gzip" and "tar".... so I executed:

ln /usr/bin/gzip /gzip
ln /bin/tar /tar           // **(because there was no "tar" in /usr/bin )**

Now, whe i run the update....

-sh-3.2$ drush -v pm update
PHP Notice:  Undefined index:  host in /usr/bin/drush on line 98

any ideas??

just bumping the issue. im still trying to figure this out. could someone wiser than I (and there are many of you out there) please chime in?? thx!!!

clearly I'm no wiser that pegleglax, because I've hit exactly the same problem:

I could also use some help.

I ran into this same problem and it turns out (at least in my case) that it was caused because safe_mode was turned 'On'. When cli php's in safe mode, only programs in the safe_mode_exec_dir can be executed. In my case, safe_mode was 'On' and 'safe_mode_exec_dir' was undefined, so no programs could be executed thru the exec() call. The work around is to turn safe mode 'Off':

cd sites/all/modules/drush
php <b>-d safe_mode=Off</b> drush.php pm update

HTH!
