Scrapy install: no acceptable C compiler found in $PATH

I am trying to install Scrapy on a a Mac OS X 10.6.2 machine... Wh开发者_如何转开发en I try to build one of the dependent modules ( libxml2 )

I am getting the following error:

configure: error: no acceptable C compiler found in $PATH

I assume I need the gcc compiler ... is that easy to install on 10.6? Is there some sort of package I should be installing, so as to not get hunged up like this installing modules in Python?

You need to install the Apple Xcode Development tools. There would be on Apple Developer Connection site or on your Mac OS X installation CDs/DVD. Ensure that the optional components for command line development are installed ("Unix Development" in the Xcode 3.x installer)

Might be of interest to know that upgrading from OS X 10.5 to 10.6 apparently unlinks the existing developer tools thus requiring a reinstall from the SL DVD for gcc to work as usual.

Most annoying when you thought you had everything set up.

You need to install XCode ('developer tools') from the Snow Leopard DVD - this includes gcc among much other stuff. You should also run software update after the install to freshen it
