ValueError: The 'rex' package was not installed in a way that PackageLoader understands.

Environment

OS: Ubuntu 21.04.4 LTS python3: 3.8.10

Problem Description

I cloned rex, ran python3 setup.py install --user, and manually installed the following dependencies:

• povsim (v9.2.1)
• cle (v9.2.1)
• claripy (v9.2.1)
• archer (v9.2.1)
• ailment (v9.2.1)
• angr/tracer (master 4fe840c).

I finally got rex to install.

Using /home/aesophor/.local/lib/python3.8/site-packages
Finished processing dependencies for rex==0.2

However, running rex triggers the following exceptions (jinja2?) I’m not sure what to do next to get rex to run. Here’s the error message I got:

Thanks in advance!
