Could not find a version that satisfies the requirement WebHelpers2 (from FormAlchemy>=1.3.8->pyramid-formalchemy>=0.4.2dev->fa.bootstrap==0.3.2) (from versions: 2.0b4, 2.0b5, 2.0b1, 2.0b2, 2.0b3, 2.0b4, 2.0b5)
Some externally hosted files were ignored (use --allow-external to allow).

Looks like this also happens if you just run pip install webhelpers2, suggesting it's a problem w/ WebHelpers2 and not with fa.bootstrap.

Explicitly doing a pip install webhelpers2==2.0rc2 before trying to install fa.bootstrap will work around the issue.
