在Mac 10.9.6中安装pycrypto时出错

Question

I am trying to install 'fabric'. I tried using 'pip install fabric' and the installation is failing when it is trying to install the 'pycrypto'

I see it is fetching the 2.6.1 version. I tried installing lower versions and I am getting same error.

'sudo easy_install fabric' also throws same error.

I also have the gmplib installed. I have the lib file in these places /usr/lib/libgmp.dylib /usr/local/lib/libgmp.dylib

This is the error i get when i execute 'fab'

Traceback (most recent call last): File "/usr/local/bin/fab", line 5, in from pkg_resources import load_entry_point File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in working_set.require( requires ) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require needed = self.resolve(parse_requirements(requirements)) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve raise DistributionNotFound(req) # XXX put more info here pkg_resources.DistributionNotFound: pycrypto>=2.1,!=2.4

Answer 1

Got it working after installing xcode.

pycrypto was installed by default once xcode was installed and fabric is working now.

(I should have mentioned that I am new to MAC in the question)
