I'm getting the following error when I try to install my extension.

Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory. 
The following modules are outdated:
Mymodule_Example data: current version - none, required version - 2.0.0

The database entry in setup_module looks like this:

enter image description here

This is my module.xml file:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Mymodule_Example" setup_version="2.0.0">
</module>
</config>

Is there something I'm missing to ensure the data version gets added to the DB? A result of this also means my setup scripts aren't running.

You already have right solution :)

Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory

In Magento1 data_version field was updated on each application call according to to it's value in config.xml.

In Magento2 you should do it manually. This on-demand approach helps to avoid such version checks during each application call.

This should work, you just need to execute following commands on terminal from magento root directory -

rm -rf pub/static/*
php bin/magento setup:static-content:deploy

After that set 777 permission to your magento root folder recursively.

You also need to delete setup row, to do that open setup_module table in your database and delete your module entry if exist.

Then run this command to register your module -

php bin/magento setup:upgrade --keep-generated

Your may clear cache if required.

Go and check "setup_module" table, the data_version is "null".

This is happens because of something wrong while running "bin/magento setup:upgrade"

So you have to fix the error then everything ok.

Temporary solution: Login to Mysql database => then update table setup_module of the "data_version" column same as "schema_version"

Just update your setup_module table with the required version, or delete in case of NULL required.

In your case, just put 2.0.0 on data column.

Create file registration.php in a your extension root directory. In example: app/code/Namespace/Modulename/registration.php

<?php
 \Magento\Framework\Component\ComponentRegistrar::register(
 \Magento\Framework\Component\ComponentRegistrar::MODULE,
 'Namespace_Modulename',
 __DIR__
 );

In case it might be helpful to anyone, aside from the above correct answers: I encountered this issue after manually deleting the module record in setup_module and then running setup:upgrade manually. It turned out that setup:upgrade failed, so a new record in setup_module was not created.

In case you're running a script like me that runs setup:upgrade in this case, make sure the action was successful, and the module actually appears in setup_module.
