I'm having an issue during the readiness check within the extension manager and is failing at the component dependency check. I've looked through all the forum posts to see if anything could put me in the right direction however it hasn't enabled me to get past this stage.
The error message that I'm getting is:
We found conflicting component dependencies.
It would be great if someone could help me out as I am very much an amateur!
Please check following Resolve component dependency readiness check issues it may help you.
As you mention - that you have conflicting issue on magento 2 extension manager wizard !
Magento devdocs already explain why this issue is occurs in extension manager here is the ref link - https://devdocs.magento.com/guides/v2.1/comp-mgr/trouble/cman/component-depend.html
another alternate option if you wanted to installed new extension in your magento 2 system
Download that extension and upload it in your magento 2 app/code directory with respective vendorname.
After that run php bin/magento setup:upgrade command
your extensions gets installed easily !
Hope it helps
