Errors when trying to install with Pip.

Hello everyone,

I'm having trouble installing from the PyPI, using pip in CMD.

I've found a package I'm interested in (orbit, https://pypi.python.org/pypi/orbit/0.2) start a VENV in CMD, punch in pip install orbit... it downloads and thinks for a while then throws back errors:

C:\Users\username\AppData\Local\Temp\easy_install-y6y867l_\lxml-3.5.0\temp\xmlXPathInit67jlgy6a.c(1): fatal error C1083: Cannot open include file: 'libxml/xpath.h': No such file or directory
*********************************************************************************
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
*********************************************************************************
error: Setup script exited with error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\cl.exe' failed with exit status 2

I've tried a couple of packages, and about half of them install and half of them throw back this error. I've also tired on my PC and my Mac and I'm getting the same result, which slightly different paths in the error message obviously

Anyone got any thoughts?

Thanks

Try the following:

python -m pip install orbit

Otherwise maybe you could try install libxm2, whatever that is...!
