error: command 'cl.exe' failed: No such file or directory

问题

I am currently trying to install PYODBC via pip but am getting an error. at this point, I am at a loss on what to do.
Here is what it looks like:

 C:\Users\c.ginther>pip install pyodbc

As user590028 mentioned in the comments python requires a C compiler to install packages like pyodbc. On Windows the most common compiler is Visual Studio C++, so check the list below taken from Microsoft Visual C++ Compiler for Python 3.4

Visual Studio 2008 for Python 2.7.

Visual Studio 2010 for Python 3.4.

Newer versions of Visual Studio should work on Python 3.5.

If you install Visual Studio you should be able to build pyodbc without any errors.
