在OSX 10.11（El Capitan）中安装Scrapy（系统完整性保护）

Question

我正在尝试通过pip在OSX 10.11（El Capitan）中安装Scrapy Python框架。安装脚本将下载所需的模块，并在某些时候返回以下错误：

OSError: [Errno 1] Operation not permitted: '/tmp/pip-nIfswi-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info'

我尝试使用以下命令停用OSX 10.11中的无根功能：

sudo nvram boot-args="rootless=0";sudo reboot

但是当机器重启时，我仍然收到相同的错误。

我的StackExchangers同事有什么线索或想法吗？

如果有帮助，则完整的脚本输出如下：

sudo -s pip install scrapy

Answer 1

我也认为绝对没有必要开始入侵OSX。我能够解决它brew install python看来，使用新版El Capitan随附的python / pip会有一些问题。

Answer 2

正如其他答案所说，这是由于新的系统完整性保护，但我认为其他答案过于复杂。如果您只想在当前用户中使用该软件包，则应该可以使用该--user标志安装它，而无需禁用SIP 。像这样：sudo pip install --user packagename
