Question

I have installed latest version of Megento 2, everything is working fine frontend, backend and functionality.

I have one issue with bin/magento setup:upgrade command, when I run this command in terminal I get below exception .

[InvalidArgumentException]
There are no commands defined in the "setup" namespace.

Magento other commans work or not ? – Lucio

Check composer.json and module.xml exist correctly under all your current modules. – Tensible

Answer 1

Please mention setup_version in your module.xml file. Your module.xml file looks like:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
  <module name="Vendor_Module" setup_version="1.0.0"/> 
</config>

You need to give full permission to both var and pub folders recursively.

sudo chmod -R 777 var pub

In my case I was missing the entire etc/module.xml file when I got that error. Adding the file allowed the command to run correctly. – Tompkins

Answer 2

Giving full control (read/write/execute) to var and pub directory should solve this issue.

sudo chmod -R 777 var pub

You may also try running the command using sudo.

sudo php bin/magento setup:upgrade

Kissable

sudo php bin/magento setup:upgrade is working fine for me. – Dniester

Answer 3

I wanted to add an answer because the others doens't cover all the problems that could generate this error :

There are no commands defined in the "setup" namespace.

in general.

This error could be caused by permission as said in others answer but we could have other scenario.

• The absense of : etc/module.xml
• An error in /etc/module.xml or in /etc/di.xml or others xml extensions under /etc
  

If you know other scenario please comment this answer.
Hope this help.

Between composer create-project and bin/magento setup:install there is only a restricted set of available commands. After install is done, all commands are in place. I don't know yet why this is happening (maybe because there is no database or config file for cache yet..), as all the modules in vendor (which imlements the commands) are present. For example there is no config:set (which i need to run before setup:install), also no cache namespace, no indexing, etc. – Typeset

Answer 4

Just remove all the directory of var and remove pub/static directory , it will work bin/magento setup:upgrade

Answer 5

I encounterd the same error while running commands related to magento. I was missing double_quotes(") in module.xml file of the custom module. So check module.xml file for any typos and setup_version.

Answer 6

I want to add one more hint check the 'MAGE_MODE' value in env.php it should be correctly set.

Answer 7

The reason for this error can be seen in the command output: php -f bin/magento.

This will work for most errors like There are no commands defined in the "..." namespace..

---

A fairly common cause is an error in the VendorName/ModuleName/etc/config.xml.

Dustproof

Answer 8

simple RUN php bin/magento this will show you details where it is broken
