Depending on how you originally tried to install that package, you'll most likely need to install the Windows binary instead:

http://biopython.org/wiki/Download

There are some Python packages that need a C compiler like in Visual Studio, or MingW (especially if you install from a package installer - like pip or easy_install). These C compilers can be a pain to set up if you are new to them.

  • yes, I installed binary version but when I want to use alignment package(clustalw, muscle...), I get errors, so I dis-install it , and I try to install biopython from package. – user3216969 Feb 04 '14 at 19:15
  • You may need to give some more context on specifically how you are trying to install those packages. There might be more information in the [biopython installation PDF](http://biopython.org/DIST/docs/install/Installation.pdf) – marminto Feb 04 '14 at 19:28

Try to get the biopython package from this link: http://www.lfd.uci.edu/~gohlke/pythonlibs/#biopython
