我正在尝试通过pip在OSX 10.11(El Capitan)中安装Scrapy Python框架.安装脚本会下载所需的模块,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
但是当机器重新启动时我仍然会遇到同样的错误.
来自我的StackExchangers同事的任何线索或想法？
如果有帮助,则完整脚本输出如下:
sudo -s pip install scrapy

Collecting lxml (from scrapy) …我正在开发一个Python程序来检测记录列表中的城市名称.我到目前为止开发的代码如下:
aCities = ['MELBOURNE', 'SYDNEY', 'PERTH', 'DUBAI', 'LONDON']
cxTrx = db.cursor()
cxTrx.execute( 'SELECT desc FROM AccountingRecords' )
for row in cxTrx.fetchall() :
if any( city in row[0] for city in aCities ) :
#print the name of the city that fired the any() function
else :
# no city name found in the accounting record
该代码可以很好地检测在会计记录中找到aCities列表中的城市,但是当any()函数返回True或False时我很难知道哪个城市(墨尔本,悉尼,珀斯,迪拜或伦敦) )触发退出.
我已经尝试过aCities.index和队列但到目前为止没有成功.
