Exceptions when installing lxml

On Mac OS 10.14.6, I'm trying to install lxml for Python 3.6 with:
> STATIC_DEPS=true easy_install-3.6 lxml
I get this exception:
Exception: Command "./configure --prefix=/private/var/folders/yd/szy02nx52b912gvn2qhh8nb40000gq/T/easy_install-_ctp1edv/lxml-4.5.1/build/tmp/libxml2" returned code 1
Here's the entire trace I get:

any help will appreciate!

Depending on your setup, you might install lxml with one of these commands:
$ apt-get install python-lxml
$ easy_install lxml
$ pip install lxml

From the looks of it you are missing Microsoft Visual Build Tools. Try installing it:
https://visualstudio.microsoft.com/visual-cpp-build-tools/
Then, restart your computer and update setup tools.
pip install --upgrade setuptools
Once that it done, try installing rpy2 again.
Hope this help!

you can download the binary file of rpy2 from https://www.lfd.uci.edu/~gohlke/pythonlibs/
by searching it in the web page and use pip install 'that binary file'
download binary file according to your python version

I don't get the issue, Can Anyone please help with this problem?

I solved the above problem by editting the path enviroments, because I figured out that I have two version of Mingw. Thus, I removed the old one.
However, I got another error while downloading Kares following the link [link]

Any suggestions ?

I can't pip install python sabyenc on raspbian linux

I can't pip install sabyenc and I need it for sabNZB to work. I googled a lot with no help at all.
Python version 2.7
pip version 1.5
Reaspbian Jessie

I had the exact same problem in Ubuntu. python-appdirs needs to be upgraded. If you have Ubunutu:
wget http://mirrors.kernel.org/ubuntu/pool/main/a/appdirs/python-appdirs_1.4.0-2_all.deb
sudo dpkg -i python-appdirs_1.4.0-2_all.deb
