EF Tools throws "Unrecognized option '--build-base-path'" inside package manager console

See original GitHub issue

I have two projects in solution: asp.net core web and core class library that contains DataContext and migrations.

The issue

It’s not possible to generate migrations with v1.1.0. The website is building and running successfully.

Steps to reproduce:

Upgrade nuget packages from v1.0.1 to v1.1.0.
Use ‘add-migration’ to generate migrations or ‘update-database’ inside package manager console
Error: Unrecognized option '–build-base-path
