Hi, Pierre.

Thank you very much for quickly reply.

Based on Pierre's advice,

I deleted the edk2 directory that I had been using and ran the git clone of edk2 again,

also used the master branch to specify the latest commit as of yesterday.

I also took Sami's advice and specified Python 3.7.

Under these conditions, the build finished successfully without any problems.

Thank you very much for your help.

Best regrads,
Shuuichrou.

Hi Shuuichrou,
I would have some suggestions/questions:
1. Is it only the ConfigurationManager module which doesn't build or is it also other modules ?
For information, '-m Platform/ARM/VExpressPkg/ConfigurationManager/ConfigurationManagerDxe/ConfigurationManagerDxe.inf' allows to build only this module and its dependencies, and '-n 1' allows you to run on one core to have logs following the build order. You can try building modules from other platforms.
2. Is the command working on the edk2's latest master branch ? Or on more recent tags (like edk2-stable202108)
3. Reset the configuration files
- Run 'git clean -x Conf/' in edk2/ (assuming you have nothing important there)
- Set your environment again to re-create them
- Re-build the FVP
4. Rebuild the BaseTools:
- cd edk2/BaseTools && make clean && make

Regards,
Pierre
