"An exception was thrown while activating λ:FluentMigrator.Runner.IVersionLoader." on Debian 11 "Bullseye"

-> https://github.com/nopSolutions/nopCommerce/issues/5946

has anyone found a solution here?

I'm having the same problem on windows 10. Would appreciate help with this.

I have resolved this problem for me now.
I have a machine which runs nopcommerce with no problem that I've set up some time ago. I've looked at my setup there - and I've noticed that I've used mysql 8.0.26 (and not the current version of 8.0.29). After switching the DB version, it now magically works. No idea what was going on, but maybe try that if no other solutions worked.

This problem is on Both Postgres / MySQL why this is happening is it about the version 4.5.2 ?
is struggling to install nopcommerce 2 months ago .
i hope anyone can help

Feedback:-
why there is no real helpdesk can solve
Windows server and shared windows hosting is very bad idea due the paid licenses that microsoft get
Support LINUX please i know this product is using Microsoft Technologies but microsoft itself now had its Own linux distro for Azure and they know that linux is better nowadays

I have the same problem ... mysql is 8.0.29 for win64 on x86_64 on windows 11

I keep getting the error An exception was thrown while activating λ:FluentMigrator.Runner.IVersionLoader.

Be it I add data or not, create the db or not ... I am at a loss here ...

Hello,
I had the same problem with th error message " An exception was thrown while activating λ:FluentMigrator.Runner.IVersionLoader" when installing on ubuntu,

my solution, follow steps in https://docs.nopcommerce.com/en/installation-and-upgrading/installing-nopcommerce/installing-on-linux.html#install-and-configure-software

except for mysql, skip it & install sql server from Microsoft at https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu?view=sql-server-ver16
I selected option3 i.e express edition, but it needs VPS of 2GB RAM min.

hope it helps.

Hope you like it!

For me on Debian 11, and MySql 8.0.29 the following worked:

edit Libraries\Nop.Data\Nop.Data.csproj

update
<PackageReference Include="MySql.Data" Version="8.0.27" />

to
<PackageReference Include="MySql.Data" Version="8.0.29" />

Recompile

Thanks :)  It's worked for me. I edited my package version to 8.0.31 (my MySQL version).
