• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

pyenv virtualenv 3.8.5
pdm version 0.10.3

After the installation is successful, I get an error when I use the pdm --help command

Actual behavior

The newest release of build introduced a breaking API change. As a workaround, you can downgrade build to <0.1.0. The bug fix will be landed with the next release.
