The version is Python 3.4 with pip, along with Visual Studio 2010 in the Windows 7 OS. When I run pip install numpy in the cmd, it gives:

File "numpy\core\setup.py", line 682, in get_mathlib_info raise
RuntimeError("Broken toolchain: cannot link a simple C program")
RuntimeError: Broken toolchain: cannot link a simple C program

    @Huu Nguyen Thank you for the answer. I read the page. However, it is dedicaded to an issue in MacOS. Mine is in Win7, so the answer is not very much help for me. – John-Annual May 30 '14 at 02:41
  • The top answer of the linked question says: Run Sudo . That doesn't help on Windows. Therefore this question deserves reopening. – Christian Aug 24 '14 at 14:26

Try to use a binary installer. You can find it here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
