Unsupported operand types and other errors on installation

Never had a problem here. Perhaps it's related to your environment? PHP version? Can you install fine using Commerce Kickstart 1.x?

Ok, not sure where to look next then. Definitely sounds like you're not getting fields created on install that should be created, but 512M should be more than sufficient memory (I do all my development at 128M). Perhaps a memory problem with some other module? There was a patch for a while in Drupal core that caused runaway memory problems by duplicating the entire entity info array multiple times on page requests that was rolled back before Drupal 7.15 was released.

Lots of problems installing Commerce 7.x-1.3 here too.

Commerce Repair seems to help a bit, but enabling the last few modules (e.g. PayPal WPS) just kills everything dead, with the error @Recoverable fatal error: Argument 2 passed to entity_views_field_definition() must be an array, null given@

I'll see if I can debug some more.

OK, I get this too. Installation in the order recommended works fine for Commerce, Customer, Price, Line Item and their UIs.

But enabling commerce_order throws lots of errors. Can recover OK using drush @site pm-disable commerce_order.

I'm using a newer version of Views, but otherwise OK. A site I installed Commerce on some time ago is still working fine with the same modules.

Address Field 7.x-1.0-beta3
Ctools 7.x-1.2
Entity API 7.x-1.0-rc3
Rules 7.x-2.2
Views 7.x-3.5

Commerce 7.x-1.3

PHP 5.3 on a Fedora machine that runs lots of other Drupal sites, including one using Commerce 7.x-1.3 that I installed some months ago and then upgraded as needed :)

Yes!!! Progress. I can install commerce_order if I do this:

1) drush @sitename pm-enable commerce_order commerce_order_ui
2) Get error messages to do with entity views, site is dead. Nothing works, not even drush.
3) Edit system table in database, set "status" from 1 to 0.
4) drush @sitename pm-enable commerce_order commerce_order_ui

I am having the same problem. My configuration:

PHP Memory limit 512MB
PHP 5.3.3-7+squeeze14
Apache/2.2.16
Drupal 7.14

Modules:
ctools: 7.x-1.2+4-dev
Entity API 7.x-1.0-rc3
Rules 7.x-2.2
Views 7.x-3.5

Commerce 7.x-1.3

This is not a fresh install though. It is a complex site with around 150 modules.
I installed Commerce 1.3 following instructions here - http://drupal.org/node/1007434.
Everything goes fine till I install the order module. Drupal gives me these notices:

Notice: Undefined index: commerce_order_total en commerce_order_entity_property_info_alter() (line 133 in /home/zzzzzzzz/sites/all/modules/commerce/modules/order/commerce_order.info.inc).
Recoverable fatal error: Argument 2 passed to entity_views_field_definition() must be an array, null given, called in /home/zzzzzzzz/sites/all/modules/entity/views/entity.views.inc on line 152 and defined en entity_views_field_definition() (line 175 in /home/zzzzzzzz/sites/all/modules/entity/views/entity.views.inc).

From then on, nothing works. I go to the database, change the status of the module form 1 to 0 and then I run update.php which makes come back to normal.
Anyway I am not able to install the order module as I dont hav access to a shell to do it through drush.
Is there any more data I can give to help out?
Any ideas how I can manage to make commerce work in full?
This module is basic for my project and I cannot go further.

PS: by the same time I am having problems with commerce I am having an 500 Internal Server Error after running cron. It takes a long time to run and at the end it gives the Internal Server Error. On every cron run drupal has to index 100 nodes and look for RSS content from some 10 or 15 blogs, but I guess this is not a big deal for drupal, is it?

And a question to Fonant. Did you manage to work with commerce_order from then on?
Thanks

Can you look in your field list (under Reports) and see if the commerce_order_total price field is listed?

At the moment I dont have "order" installed and this field doesn't exist. Is there more info I can give you?
thanks

You must have the Order module installed if commerce_order_entity_property_info_alter() is being called. : ?

ok, that notice comes when I try to install order module.
I just did it and this was the message by drupal:

FieldException: There has been an attempt to create an instance of the field commerce_line_items in the package commerce_order that already has an instance of this field. in field_create_instance() (line 490 in /home/zzzzzzzzzzzz/modules/field/field.crud.inc).

well, this is a quick translation from spanish...

i hope it helps!

after that, I cleared the caches and this was the message:

Mensaje de error

Notice: Undefined index: commerce_order_total en commerce_order_entity_property_info_alter() (línea 133 de /home/zzzzzzz/sites/all/modules/commerce/modules/order/commerce_order.info.inc).

after that whenever I go to any page it gives this fatal error:

Fatal error: Unsupported operand types in /home/zzzzzzzz/sites/all/modules/entity/entity_token.tokens.inc on line 93

hope it helps!

Sounds like perhaps you had this module installed but the uninstalled or disabled it and now it's trying to create what it thinks is a duplicate field?

Well, I just did another try.

1. I installed order module
2. I got the first error message
3. I went to the database and put status 0 to order module
4. went to admin/modules/list where order module appeared disabled
5. Enabled order module again
6. now I have the commerce_order_total field in the field reports, it appears as a blocked field.
7. now everything looks to work fine.

I will install order UI module to see what happens...

1. I just installed order UI module... and everything looks to work fine!!

I am very happy at the moment!

I am going to try with the rest of the commerce modules and I will write down the results!

thank you very much!

Well, here comes the problem again, even though this one is different:

After success in installing order and order UI modules I went on with: checkout, payment, product following the order in http://drupal.org/node/1007434
everything ok so far.

The new problem comes with installing product_reference module. Once installed I got this notice:

Notice: Undefined index: commerce_total en commerce_line_item_entity_property_info_alter() (línea 101 de /home/zzzzzzzz/sites/all/modules/commerce/modules/line_item/commerce_line_item.info.inc).

after that, the following fatal error:

Fatal error: Unsupported operand types in /home/virtualmin/diagonalperiodico.net/public_html/nuevaweb/sites/all/modules/entity/entity_token.tokens.inc on line 93

So far I havent been able to recover the site (I made a backup though).

I tried disabling the module by hand and then running update.php
after running update.php I got this notice and error:

Notice: Undefined index: commerce_total en commerce_line_item_entity_property_info_alter() (línea 101 de /home/zzzzzzzzzzz/sites/all/modules/commerce/modules/line_item/commerce_line_item.info.inc).
Recoverable fatal error: Argument 2 passed to entity_views_field_definition() must be an array, null given, called in /home/zzzzzzzzzzz/sites/all/modules/entity/views/entity.views.inc on line 152 and defined en entity_views_field_definition() (línea 175 de /home/zzzzzzzzzzz/sites/all/modules/entity/views/entity.views.inc).

after this errors, everything went wrong:

Fatal error: Unsupported operand types in /home/virtualmin/diagonalperiodico.net/public_html/nuevaweb/sites/all/modules/entity/entity_token.tokens.inc on line 93

Any ideas on how can I install commerece modules properly? Am I doing something wrong?

Oh, I see what you're doing - yeah, you can't just disable a module like that in the system table. The disable / uninstall process for Drupal modules involves, among other things, cleaning up leftover data and configuration that is no longer necessary - such as defined fields. I think you may have just backed yourself into a corner because you've put your site in a broken state where Drupal is assuming a module was removed through the normal method when in fact it was not.

I'll look into it more when I have time, but there's not much we can do from a core Commerce standpoint to fix that sort of problem.

Thanks for the quick answer.
I know what I am doing is wrong in the way that I shouldn't disable modules by hand in the database.
The problem is that from the beginning I am doing things "in the right way" and nothing works, I am not even able to install the commerce modules...
Well, thanks anyway, if I finally get to a solution I'll try to write it down here just in case anyone finds the same problem.

I have a queue of issues to work through, but I won't forget this one. ; )

If you have the time / ability, where I'd begin looking for a fix is to see if we can accommodate these "zombie" field instances in our install process, reusing them instead of failing because they already exist.

I hope you have the time soon, rszrama. : )
For the moment I tried it again uninstalling and cleaning everything up with the help of shaisamuel at http://drupal.org/node/1480106 but it didn't work and I cannot figure out what it can be.
I executed the php script to clean up everything, and it gave me an error in the output that can be the problem, you can follow it at: http://drupal.org/node/1480106.
anyway I tried again the installation of the commerce suite and after enabling the order and order UI modules drupal gave me the following errors:

Notice: Undefined index: commerce_order_total in commerce_order_entity_property_info_alter() (line 133 in /homezzzzzzzzzzz/sites/all/modules/commerce/modules/order/commerce_order.info.inc).

    Recoverable fatal error: Argument 2 passed to entity_views_field_definition() must be an array, null given, called in /home/zzzzzzz/sites/all/modules/entity/views/entity.views.inc on line 152 and defined en entity_views_field_definition() (line 175 in /home/zzzzzzzzzzzz/sites/all/modules/entity/views/entity.views.inc).

After that everything broke again, gave me this fatal error:
Fatal error: Unsupported operand types in /home/zzzzzzz/sites/all/modules/entity/entity_token.tokens.inc on line 93

Well, I will keep trying tomorrow and if I find the way I will post it here.

Well, I finally got it!

finally what helped me to figure it out was taking into account what is said in this issue:
Recoverable fatal error: Argument 2 passed to entity_views_field_definition() must be an array

I've just done as Fonant suggested but I only disabled "Order" in the "system" table of the database and then re-enabled it via Drupal->modules.

After that I ran commerce_repair module, but taking into account that whenever I tried to run it as user/2 (not user 1 but with administration privileges) it didn't allow me to do it, but running it with user/1 commerce_repair was able to repair all fields necessary.
Well! I hope this helps to anyone that arrives to the same problem!
Finally I will be able to use the famous commerce module in my site!
thanks!

lol Sorry it was such a headache to get up and running in the first place, but glad you're in business now. ; )

All of symptoms described are fixed in the patch attached to #1509994: Missing entity property info results in notices / WSOD / fatal errors during installation.
Marking as fixed - re-open if the problem remains even with the patch.

Marking as duplicate; if that patch doesn't end up solving this, we can re-activate it.
