How to solve this error?

Answer 1

Give write permission to the generated folder.

If in windows right click the generated folder and remove the read-only flag.

or if in linux.

Go the magento root folder and run this command.

sudo chmod -R 777 generated/

Hope this helps.

Answer 2

Set up one owner for default or developer mode

In default or developer mode, the following directories must be writable by the user:

• vendor
• app/etc
• pub/static
• var
• Any other static resources
• generated/code
• generated/metadata
• var/view_preprocessed

Set up one owner for production mode

When you’re ready to deploy your site to production, you should remove write access from files in the following directories for improved security:

• vendor
• app/etc
• pub/static
• var
• Any other static resources
• generated/code
• generated/metadata
• var/view_preprocessed

Make code files and directories read-only

• Enter the following command to change to production mode

---

php bin/magento deploy:mode:set production

• Enter the following command

---

find app/code var vendor pub/static app/etc generated/code generated/metadata var/view_preprocessed \( -type f -or -type d \) -exec chmod u-w {} + && chmod o-rwx app/etc/env.php && chmod u+x bin/magento

• Enter the following command as a user with root privileges

---

find app/code lib pub/static app/etc generated/code generated/metadata var/view_preprocessed \( -type d -or -type f \) -exec chmod g-w {} + && chmod o-rwx app/etc/env.php

Make code files and directories writable

find app/code lib var generated vendor pub/static pub/media app/etc \( -type d -or -type f \) -exec chmod g+w {} + && chmod o+rwx app/etc/env.php

ok, it seems clear the issue is permissions related.

Now, on windows, you may have some hurdles that could be simply resolved on linux.

I found the article https://mage2.pro/t/topic/4734/8 being close to your issue.

I would attempt to find the way to:

1. find the user for your webserver running
2. ensure the user you found is owner of the folder generated and apply this change recursively
3. restart your webserver
