admin area getting error 'require is not a function at editor.js:6' after upgrading magento 2 from 2.1.1 to 2.1.17

Question

After upgrading Magento from version 2.1.1 to 2.1.17, I am facing this error

Uncaught TypeError: require is not a function at editor.js:6

across admin area especially in edit pages

when I look at html -> head I see that js file

en_US/Magento_Backend/js/bootstrap/editor.js

is called first before requirejs file

Please help

Answer 1

Delete the existing require js from pub/static/_requirejs/frontend/Namespace/Theme/en_US requirejs-config.js path and refresh the page again so it will regenerate it and solve the error of js not found.

OR

Follow below steps . I think it's solve your problem

1. Remove Your Cache
2. Clean theme by command : grunt clean
3. Run CMD command prompt with administrator privilege
4. run command : grunt exec:yourthemename
5. run command : grunt less:yourthemename
6. run command : grunt watch

Basically working and the right solution, but with the limitations of #6367
