I recently compiled and installed MAGE by running the following command:
python3 setup build -p /usr/lib/memgraph/query_modules
I used the latest main branch for this (https://github.com/memgraph/mage). However, when I start up Memgraph, I receive numerous error messages indicating that the Python modules are missing dependencies.
This is the part of the error message:
[2023-09-18 07:53:41.139] [memgraph_log] [warning] Replication configuration will NOT be stored. When the server restarts, replication state will be forgotten.

It is called setup but that might be confusing. What the command does, is it installs all the C++ stuff and copies Python modules without installing all the dependencies. To install the dependencies, run python3 pip install -r python/requirements.txt.
