Installing biopython

[m.nyine]

Dear all,

I have trouble getting biopython installed on my mac.

When I tried installing it via the terminal I got the following error:

"unable to execute llvm-gcc-4.2: No such file or directory
error: command 'llvm-gcc-4.2' failed with exit status 1"

I have python on my mac

"Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05)
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information"

In my understanding there is a C-compiler (GCC 4.2.1)

How come the error says command 'llvm-gcc-4.4' failed?

Thank you

Moses

What happens when you type 'gcc' to terminal (without the ' ')?

Have you installed Xcode from the App Store yet (free, just a large download)?

Have you installed the command line tools from within XCode yet? (again, free)

Once you've done that the Apple flavour compliers should all be available to Biopython and other command line tools you may in future wish to install.
