problems installing scrapy on osx 10.10.3 using pip

Question

I am unable to install Scrapy on osx 10.10.3. I ran pip install Scrapy and received the error message below indicating that twisted cannot be installed. I ran xcode-select --install to ensure that xcode tools are installed. I also tried running sudo pip install Scrapy. Any suggestions?

here is the error message I receive:

Answer 1

The hint is right there in the error message:

Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

However, I would recommend against running the actual installation as root. Just accepting the XCode license once by doing

sudo xcodebuild -license

and then re-running the installation should do the trick.
