Pip Installation Error - Command python setup.py e

问题:

I have just installed Python 2.7.5 on a Windows 7 (32-bit) box.

When trying to install Scrapy module via the Windows console I get the below error:

Command python setup.py egg_info failed with error code 1 in c:\users\compaq\app
data\local\temp\pip_build_COMPAQ\pyOpenSSL
Storing debug log for failure in C:\Users\COMPAQ\pip\pip.log

I have read other threads on this, suggesting that setup tools be re-installed or updated. I have already attempted this (the latest setup tools exist) but the scrapy install error remains.

The below is the full install script and failure:

回答1:

pip tries to build packages from source. So you'll need development headers for libraries and VS2008 compiler, all of which is rather painful to set up.

It's easier to download prebuilt binaries for failed packages from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/

And then retry installing scrapy.
