Error with lxml==3.6.2 in setup.py

[McAwesomeville]

I have installed revision 0.5.3 to Win10 with Python 3.7.1.
Installing with pip lead to an error (and it was an old revision) (see Issue #9).
The following steps worked:

1. Install Shapely according the homepage https://pypi.org/project/Shapely/ using the wheels from http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely
2. Clone the repository
3. Change to the directory of the repository
4. Change the install requirements for lxml in setup.py from
   install_requires=["lxml==3.6.2", "Sphinx>=1.3.1","Jinja2>=2.7.3", "shapely>=1.5.13"], to install_requires=["lxml>=3.6.2", "Sphinx>=1.3.1","Jinja2>=2.7.3", "shapely>=1.5.13"], (lxml is installed in revision 4.2.5). Installing swoop with the following commands leads to the error messages listed at the end.
5. Build Swoop with the command python setup.py build in the command line
6. Install Swoop with the command python setup.py install --record file.txt in the command line

Error listing without changed setup.py in step 4:
