Dlib installation python 2.7 - python-2.7

Question

Former marine grunt here! New to python and coding. Trying to install DLIB for python 2.7. I run the command pip install dlib and keep getting this error message:
Collecting dlib

The CMAKE_C_COMPILER:

To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

Any feedback or help would be great! Former jarhead so bear with me, thanks.

Answer 1

Try this:
conda install -c menpo dlib=18.18

Answer 2

First Install all the dependencies for dlib library :->
sudo apt-get install python-dev python-pip
sudo apt-get install build-essential cmake pkg-config
sudo apt-get install libx11-dev libatlas-base-dev
sudo apt-get install libgtk-3-dev libboost-python-dev

First you need to have pip installed. Then you can download the dlib python 2.7 version from "https://pypi.python.org/pypi/dlib/18.17.100" website where you will get wheel of dlib. And then use normal procedure like pip install 'path to dlib wheel'.
For ex. f you have saved .whl file to downloads folder then type pip install C:\Users\XYZ\Downloads\dlib-18.17.100-cp27-none-win32.whl.
This will surely work. When I tried I didn't get any error and dlib got successfully installed.
Cheers

The pip package might be broken or might not be updated. Anyway, download the dlib_master from :https://github.com/davisking/dlib.git
After that there is an easy guide for installation in python. Go to the folder containing setup.py and then open terminal or whatever and type
sudo python setup.py install.
