I am trying to install kivy but pip is giving me this error

Command "/usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-build-9rd60o0h/kivy/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-h2wevr4m-record/install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in /tmp/pip-build-9rd60o0h/kivy/

Error code 1 is "permission denied" - most likely, as you're on Ubuntu, I'd guess you're trying to install the module globally. Either
pip install --user kivy to install is into your user's local environment, or
sudo pip install kivy to install it globally, as root

Fail to install objccheckstyle using pip in Mac OS X

I'm trying to install objccheckstyle with this command:
sudo pip install objccheckstyle
But it fails after it says
Running setup.py install for lxml
and I get this error:
Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/private/tmp/pip-build-DsaKIL/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-CFc6EG-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/tmp/pip-build-DsaKIL/lxml
I also tried sudo pip install lxml, but it looks like it fails when tries to import libxml:
#include "libxml/xmlversion.h"
I don't find libxml with pip install. What could I be missing?
Thanks

Updating to the latest Xcode's command line tools solved the problem.
