Error in Pip install

[aalok-sathe]

When I try pip install ., I run into

'setuptools.build_meta' has no attribute '__legacy__'

Following some recommendations online, I also tried pip install . --no-use-pep517, however, to no avail, since that leads to ImportError: No module named 'skbuild'.

Full installation error output:

I run into a similar problem where I got ImportError: No module named 'setuptools.build_meta'. I'm running it in virtualenv and it got fixed by creating the virtualenv without -system-site-packages flag. It doesn't seem like you are running it in a virtual environment. If you haven't you can check out this thread for a more detailed discussion. I think there is someone having the same issue without using virtualenv.
