Hi,
I just got a new computer and am having trouble setting up ROOT but have no idea how to fix it. This is the error I am getting:

Hello,
Have you tried with the macOS binary packages: https://root.cern/install/#macos-package-managers
Cheers,
Jakob
If I’m not mistaken the binary packages are compiled with python 2, but I need to be using python 3? Let me know if that is incorrect
The latest binaries should be compiled with both python 2 and 3 support. But I’ll let @etejedor confirm.
I tried installing using homebrew but got this error upon trying to import ROOT in python:

During handling of the above exception, another exception occurred:

ImportError: Failed to import libcppyy3_7. Please check that ROOT has been built for Python 3.7
You can try with the pre-built binaries from the download page. If this does not work, perhaps @etejedor can help?
Hi,
The binary releases for MacOS are only distributed with Python2 compatibility, so you can’t use them if you want Python3, indeed.
The homebrew error is saying that ROOT was not built for Python3.7, which is the version you are trying to use. It might have been built for Python3.8, so you could try with that version.
Another alternative is to build from sources. For the VDT error, I would need @oshadura to comment.
for VDT, I will need the content of /Users/Trevor 1/Desktop/Research/root-6.22.00_builddir/VDT-prefix/src/VDT-stamp/VDT-configure-*.log
Thank you!
Oksana.
Here is the content you asked for

DIAG option is now off, building library only

CMake Generate step failed. Build files cannot be regenerated correctly.
Also, thanks so much to everyone trying to help!
hi @trevajrussell can you try to turn off vdt using -Dvdt=OFF?
@oshadura I still get the same error, but this time it occurs at 13% rather than 0. Also the log has the same content as before
I think you need to have clean build, can you try to turn to remove everything, again turn off vdt using -Dvdt=OFF -Dbuiltin_vdt=OFF ?
