Question

I bought a new macbook and I am so new to mac os. However, I read a lot on internet about how to install scrap

I did everything, but i have a problem with installing lxml

I tried this on terminal

pip install lxml

and a lot of stuff started to be downloading and many text was written on the terminal, but i got this error message on red in the terminal

1 error generated.

error: command '/usr/bin/clang' failed with exit status 1

and now when I call scrapy spider that words with lxml, i got this error message

ImportError: No module named lxml.html

what should I do please?

Answer 1

I had that problem, and what I did is:

installed all xcode (2.8GB) from apple store.

to be sure that the installation is successfully finished: open terminal and typed

xcode-select -p

you should get something like this:

/Applications/Xcode.app/Contents/Developer

now you need to install command line tools. try to type gcc on the terminal, then there are two possibilities: either you get a window asking to install the tools and you have to click on install, or you will get an error message.

if you get an error message, then don't worry just try to install the tools using this command xcode-select --install

after that restart the mac and then re install lxml again like this :

pip install lxml

then try to run scrapy again

if you encounter any other error on any other library, easily just reinstall scrapy using easy_install and NOT using pip
