我想在OS X El Capitan上向/ usr/bin移动一些东西.我使用以下命令禁用了rootless:sudo nvram boot-args="rootless=0"; sudo reboot但是我一直收到同样的错误:

MacBook-Air:~ Mark$ sudo cp class-dump /usr/bin
Password:
cp: /usr/bin/class-dump: Operation not permitted
MacBook-Air:~ Mark$ sudo mv class-dump /usr/bin
mv: rename class-dump to /usr/bin/class-dump: Operation not permitted

我想导入wordnet字典但是当我导入字典表单时,wordnet我看到这个错误:

 for l in open(WNSEARCHDIR+'/lexnames').readlines():
IOError: [Errno 2] No such file or directory: 'C:\\Program Files\\WordNet\\2.0\\dict/lexnames'

我在这个目录中安装wordnet2.1但是我不能导入请帮我解决这个问题

import nltk
from nltk import *
from nltk.corpus import wordnet
from wordnet import Dictionary

print '-----------------------------------------'
print Dictionary.length
