无法在我的Mac上安装Scrapy

Question

我目前正在使用Mac OS X 10.11.1 El Capitan.我在我的mac上安装了python 2.7和3.5.我也安装了pip.但是,我总是无法在我的Mac上安装scrapy.

我用了

$sudo pip install scrapy

它总是发现错误.(像这样)

 1 error generated.
Compile failed: command 'cc' failed with exit status 1

*********************************************************************************
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
Perhaps try: xcode-select --install

error: command 'cc' failed with exit status 1

还有这个..

Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/private/tmp/pip-build-veAN2s/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-8tLCDw-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/tmp/pip-build-veAN2s/lxml

谁能告诉我问题和解决方案是什么？

Answer 1

xcode-select --install

自升级以来,您可能还没有更新代码命令行工具.
