FIX:

Install a newer version of pytimeparse from upstream:
sudo yum -y install https://kojipkgs.fedoraproject.org//packages/python-pytimeparse/1.1.5/1.fc22/noarch/python-pytimeparse-1.1.5-1.fc22.noarch.rpm

Alternately -
1.Get a requirements file from https://github.com/openstack/gnocchi/blob/master/requirements.txt
2. Check pip is installed:
    which pip
/usr/bin/which: no pip in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/heat-admin/.local/bin:/home/heat-admin/bin)
3. Install pip
    curl -O https://bootstrap.pypa.io/get-pip.py
    sudo python get-pip.py
4. Install requirements:
    sudo yum install postgresql-devel.x86_64
    sudo pip install -r requirements.txt
5. Try again:
    sudo gnocchi-dbsync
