There are no commands in the setup namespace: Magento 2

Question

I installed the latest version of Megento 2 , everything works fine, interface and functionality.

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

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

Screenshot:

Is there something I missed during the installation, or do I need to install some kind of package for it to work?

Answer 1

Please specify setup_version in the module.xml file. Your module.xml file looks like this:

 <?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 provide full resolution for var and pub recursions.

 sudo chmod -R 777 var pub 

Answer 2

Providing full control (read / write / execute) to the var and pub directory should solve this problem.

 sudo chmod -R 777 var pub 

You can also try running the command using sudo .

 sudo php bin/magento setup:upgrade 

Answer 3

I wanted to add an answer because others do not cover all the problems that might cause this error:

There are no commands in the setup namespace.

generally.

This error may be caused by permission, as said in other answers, but we may have a different scenario.

• Missing: etc / module.xml
• Error in /etc/module.xml or in /etc/di.xml or other xml extensions under / etc
  

If you know another scenario, comment on this answer.
Hope this help.
