# patch the project definitions in-place
# replace all lower bounds with exact bounds
# delete all lines referring to psycopg2 --- so no postgres support
# but make the pyopenssl 17.0, which can work against an
# OpenSSL 1.1 compiled cryptography (as older ones don't compile on Travis).

# There are almost certainly going to be dependency conflicts there, so I'm going to use plain pip to install rather than poetry.

# Can't pip install with -e. Error message:
# > A "pyproject.toml" file was found, but editable mode currently requires a setup.py based build.
# Needs PEP 660 support in poetry, sigh. See

# So instead, make a virtualenv and install in there.

# At the time of writing, this notes:
#  ERROR: ldap3 2.9.1 has requirement pyasn1>=0.4.6, but you'll have pyasn1 0.1.9 which is incompatible.
# Helpfully, pip doesn't indicate the error; it returns 0.
# TODO: bump pyasn to >=0.4.6?
