override product/price/msrp.phtml template

Question

In my module I created \view\frontend\layout\catalog_product_prices.xml

<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
    <referenceBlock name="render.product.prices">
        <arguments>
            <argument name="default" xsi:type="array">
                <item name="prices" xsi:type="array">
                    <item name="msrp_price" xsi:type="array">
                        <item name="render_class" xsi:type="string">Magento\Catalog\Pricing\Render\PriceBox</item>
                        <item name="render_template" xsi:type="string">MyVendor_MyModule::product/price/msrp.phtml</item>
                    </item>
                </item>
            </argument>
        </arguments>
    </referenceBlock>
</layout>

but my custom product/price/msrp.phtml template did not override core template. What am i doing wrong?

Let's assume that the name of your module is Yourvendor_Yourmodule.

1. Create app/code/Yourvendor/Yourmodule directory

2. Create file app/code/Yourvendor/Yourmodule/registration.php:

   \Magento\Framework\Component\ComponentRegistrar::register(
       \Magento\Framework\Component\ComponentRegistrar::MODULE,
       'Yourvendor_Yourmodule',
       __DIR__
   );
   

3. Create file app/code/Yourvendor/Yourmodule/etc/module.xml:

   <?xml version="1.0" ?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
   <module name="Yourvendor_Yourmodule" setup_version="1.0.0">
       <sequence>
           <module name="Magento_Catalog"/>
           <module name="Magento_Msrp"/>
       </sequence>
   </module>
   </config>
   

4. Create file app/code/Yourvendor/Yourmodule/view/base/layout/catalog_product_prices.xml:

   <?xml version="1.0"?>
   <layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
       <referenceBlock name="render.product.prices">
           <arguments>
               <argument name="default" xsi:type="array">
               <item name="prices" xsi:type="array">
                   <item name="msrp_price" xsi:type="array">
                       <item name="render_class" xsi:type="string">Magento\Catalog\Pricing\Render\PriceBox</item>
                       <item name="render_template" xsi:type="string">Yourvendor_Yourmodule::product/price/msrp.phtml</item>
                   </item>
               </item>
               </argument>
           </arguments>
       </referenceBlock>
   </layout>
   

5. Create file app/code/Yourvendor/Yourmodule/view/base/templates/product/price/msrp.phtml and put some content in order to be sure that it's used on frontend.

Perform following commands:

php bin/magento cache:clean
php bin/magento setup:upgrade

Depending on your environment setup and mode, you'll have to execute

php bin/magento setup:di:compile

Go to the page with msrp set, and check if it works.

If it still doesn't work

Check \Magento\Framework\Pricing\Render\RendererPool. If you have installed debug, you can observer findDataByPattern() function in order to see what renderer is getting assigned. If you don't have xdebug, then just put $renderers = $this->getData(); var_dump($renderers['default']['prices']); die(); somewhere in findDataPattern() and check what templates are used for rendering different type of prices.
